1.1.4 Remaining Storage

For your convenience, this is displayed similarly to the battery level, showing "remaining space".


1.1.5 Host/Node

The first device connected to DWARF 3 is the Host, and the second is the Node. The Host can observe and control DWARF 3, while the Node can only observe. (Suitable for family gatherings or friends' get-togethers scenarios.)

*Currently, DWARF 3 can simultaneously connect to one host and two nodes.

*You can open the Host lock function and get control of it all along. On Host lock closed the Node might seize the control authority and become the new host if the host backgrounds the app and loses connection to it.


*So if you don't want to lose control of your DWARF 3, always keep the Host Lock on. Instead, if you want to change the controlling device, you must first turn off the host lock on the host current device and then disconnect. After, connect with another device, and this device will become the new host. (If the new device has already connected as Node, a re-connect is needed to make it the new Host.Restarting the telescope can also reset the current host memory.

10. Firmware Version: The firmware version of DWARF 3. What is Firmware you might ask, Firmware is the built-in system of the DWARF Telescope, requiring regular updates like your app, adding new features.

11. Firmware Upgrade: Access the firmware upgrade process here. Follow the prompts to complete the upgrade. When connected to the internet, a red dot will indicate if an update is needed. See the help center for detailed upgrade instructions.

*Notes: If you are having problems upgrading the firmware, kindly contact our team via [email protected]

12. Reboot: Restart DWARF 3, and you'll find it shows "No available device" in "My Device" after a reboot.

13. Shut Down: Allows you to remotely shut down/reboot DWARF 3 when it is not at hand.

1.4.2 Connection Settings 

1. Active Wi-Fi at Startup: For direct connection, the phone connects to the DWARF 3 hotspot and controls via this Wi-Fi signal. When DWARF 3 is powered on, it automatically sends a Bluetooth signal for password pairing and commands to activate its Wi-Fi hotspot. Enabling this option bypasses the Bluetooth step, allowing the DWARF 3 to start its hotspot signal upon powering on. 

*Note: This feature must be set while connecting to DWARF II and requires a restart to take effect.

2. STA Mode: Besides the direct connection, STA mode uses your home router as a relay for signal transmission and control, providing internet access for your phone while operating DWARF 3. 

Don't forget to hit connect from the homepage after configuring your home Wi-Fi for DWARF 3. 

*Notes: 

  • In this mode, both DWARF 3 and your phone will connect to your home Wi-Fi, so DWARF 3's Wi-Fi won't activate. For those who frequently use STA mode, it's advisable not to enable Active Wi-Fi at Startup and vice versa. If you feeling messed up with all the signal explanations, just remember this one line.
  • For networks that have been previously configured, DWARF 3 will remember the password, so you won't need to re-enter it. Also, remember to turn off STA mode if you take DWARF 3 to a new place.
  • Remember to use this mode occasionally, as DWARF 3 will only in this mode get a connection to the Internet. If there are any updates, you'll receive a red dot notification for updates in the 'Firmware Update' and 'About' sections.
  • STA mode allows for a longer control distance, approximately 10 meters.
  • If you're using a LAN-Node setup over a large spatial range, you can still use DWARF 3. 

    First, initiate the STA connection process, and ensure that both DWARF 3 and your mobile device connect to the same SSID that covers DWARF 3's sitting location (if using a mesh network, connect to the same node). Then, when moving to a different SSID's coverage area, manually switch your mobile device's network in the phone settings to another preferred SSID. 

    *The system will prompt you to switch back to the previous network; simply ignore this prompt. 

    Remember, as long as DWARF 3 and your mobile device are connected to the same LAN network, you can use them normally.

3. Enable 2.4 GHz: Normally, DWARF 3 defaults to send out a 5GHz hotspot signal. This setting allows DWARF 3 to emit a 2.4 GHz signal, supporting connections with not very up to date devices (struggling to find a neutral word 😣 ). Note that 2.4GHz transmission will cause certain lag.

4. Wi-Fi Compatible Mode: In regions where Bluetooth can't activate DWARF 3's hotspot, this mode can be a solution, try it out, no harm.

5. Region: To comply with network communication standards, please select your current locating country/region.


1.4.3 Location

1. Set Location Automatically

Automatically retrieves your geographical location. Ensure your phone’s GPS is on and DWARF 3 has permission to access your location.

2. Set Location Manually

In areas without GPS signal, like deep mountains, turn off automatic location and enter coordinates manually.

*Note: Correct coordinates are crucial for accurate star observation calibration and locating.

1.4.4 General

1. Language: Currently offers English and Chinese, more languages are to be added.

2. Appearance: Choose between Dark/Light mode or follow system settings.


1.4.5 Support

In this part, you can upload the log for DWARF 3 if there is any problem.

Log Upload: DWARFLAB app automatically records DWARF 3 logs while you are using it. Repeat the process causing the error or identify the time it occurred and upload the relevant log.

2. Shooting Interface Introduction

2.1 Exit

Click to exit the shooting interface and return to the homepage.

2.2 Dual Lenses Switch

❗️The dual-lens system helps in quickly locating targets. Please read the following tutorial with devotion❗️

Open/Close Dual View: Click to open/close the dual views.

Switch View: Click to switch between views.

View Indication: The telephoto view shows the content within the green frame in the wide-angle view.

Double-clicking on the telephoto view enables auto-focus.

*Note: The wide-angle lens cannot focus and can only be used in taking photos in photo mode.

Dual Lenses Locating: Switch to and double-click the wide-angle view moves the green frame indicator (telephoto view). This feature allows you to locate and quickly focus on objects in the wide-angle lens, like birds in the backyard, pedestrians on the street, or celestial bodies in deep space.

*Notes: 

  • The dual-lens system may occasionally be out of sync when switching targets at different distances. Performing auto-focus restores it.
  • In the dual-lens system, the wide-angle lens can only take photos in Photo/ Burst/Time Lapse mode and acts as a wide view indicator in other modes.
  • You cannot proceed with auto focus by this method when in Astro Mode.

2.3 Guide

Guide, helping you quickly understand the shooting process. We have prepared corresponding tutorials for different modes. Any time you forget what to do next, click here to get some hint.

2.4 Joystick & Speed Control

1. Move the joystick to navigate your lenses, and use the speed wheel to adjust its movement speed.

2. Click to switch to the arrow panel for more precise control.

Tips: You can quickly and precisely locate your target by combining the following three methods:

  • Manually rotate the lenses to roughly align with the target.
  • Use dual-lenses locating to align the target.
  • Adjust the lens position finely with the joystick/arrow panel.


2.5 Temperature

Display the temperature of the sensor. This data assists in assessing whether the temperature of your existing dark frames matches the current conditions. If there's a significant discrepancy(>8 ℃), retaking dark frames may improve your results.


2.6 Battery and Storage

Displays the remaining battery and memory. 

*Note: It's important to maintain sufficient battery power. Firmware updates cannot be performed below 20% battery, and astronomical shooting automatically stops below 8%.


2.7 Status Indicator

Helps you tell whether you have control and are in good connection with DWARF 3. 


2.8 Album

Click to enter the album.


2.9 Select Mode

Click here to choose different shooting modes. Tutorials for each mode are in the next section.


2.10 Shoot

The shooting button, click to start shooting.


2.11 Focus

Click 'Auto' for auto-focus, or use the  +/- to manually focus. In case you don't know, you can long press +/- and get a proper focus quicker. DWARF II is suitable for focusing on targets at a distance of 3 meters or more. Focusing on targets less than this away may result in autofocus failure.*Note: The Auto button turns green during focusing and reverts to white once focus is achieved.


2.12 Function

Includes Feature (Box Symbol)and Parameter Setting(Adjuster Symbol).


2.12.1 Feature

Each shooting mode has unique features to choose from, like in Photo mode, there are object tracking, sun tracking, and moon tracking.


2.12.2 Parameter Settings

Tele and Wide angle lenses parameter adjustment.

Exposure/Shutter: Adjust shutter time. Automatic shutter setting is always recommended for daytime. More to be introduced for astrophotography exposure in the next section tutorial.
Gain: Adjust the gain setting. Keep between 0-30 for daytime normally. More to be introduced for astrophotography gain in the next section tutorial.

Preset: Support quick apply of preset parameter sets, allowing you to apply commonly used settings (exposure, gain, resolution) in one tap.Current constraints:
  1. Due to the need for dark frames with the same parameters in taking astrophotography, the current preset feature only includes parameter sets for which dark frames have already been captured.

  2. The preset feature for telephoto can only be accessed when tracking a target in astro mode. The wide-angle preset parameters, however, are not restricted and can be accessed freely.

  3. We will continue optimizing the parameter adjustment workflow to provide a more user-friendly interface for you.

Filters:

DWARF 3 has 3 built-in filters.

  1. The VIS filter is designed to block ultraviolet and infrared light while allowing visible light to pass through. It is particularly effective within the visible light range of approximately 430-650nm, enabling the capture of most visible light while reducing the impact of ultraviolet and infrared wavelengths. This makes it suitable for general photography applications.

  2. The Astro filter, on the other hand, is designed to allow infrared light to pass while blocking ultraviolet light and a portion of visible light. It is effective within the combined visible and infrared range of about 430-690nm, making it ideal for infrared photography as it enables the capture of infrared light above 650nm while minimizing the effects of ultraviolet and shorter visible wavelengths.

  3. The Dual-band filter is specifically designed to pass two particular wavelengths of light: Hα (656.3nm) and OIII (500.7nm), which are highly beneficial for observing emission nebulae. The bandwidth (FWHM) for Hα is approximately 15±3nm, and for OIII, it is around 30±3nm. This filter enhances the visibility of emission nebulae by selectively transmitting Hα and OIII light while blocking other wavelengths.
In astrophotography, the Astro filter is often used for calibration to ensure accurate capture of infrared light. The DWARF 3 lens is capable of focusing light within the 430-700nm range effectively, which helps prevent issues such as star bloat and other issues.

White Balance: Usually set to automatic; adjust to warmer temp. when you feel like getting a yellow or orange sun/moon.Other Settings: Feel free to experiment with different parameter adjustments.
 *Very Important Notes About Parameter (stop being mad at brightness changes and learn about the rules): 

  • In Astro Mode, when you click 'auto-focus', 'calibration', or 'Go Live' after a shooting session, the settings will automatically adjust to a shutter speed of 1s and a gain of 120. This helps DWARF 3 maintain the proper brightness for calculating the position of celestial bodies, also known as 'plate solving' .
  • The scope automatically detects the sun/moon and adjusts the appropriate shutter and gain values on hitting auto-focus.
  • Due to those auto acts above, it's advised to adjust settings right before pressing shoot button to avoid having to re-adjust after automatic changes.


3. Tutorial For Different Modes

3.1 Photo Mode

3.1.1 Wide-Angle Photography

Adjust settings to take normal photos with the wide-angle lens, which cannot focus.


3.1.2 Telephoto Photography

Target Locating: Move the joystick or use dual-lenses locating to move the target to the center of the wide-angle view. 

Focus, adjust settings, and shoot.


3.1.3 Object Tracking

Move the joystick or use dual-lenses locating to move the target to the center of the wide angle view. 

Switch to the telephoto lens and focus (auto/manual).

Activate 'Function-Feature-Object Tracking' and track the target by dragging a box over it.

Click 'Stop' to end tracking and Exit to leave the mode.

*Note: 

Object Tracking, where you tap and select to track a moving object, is different from Sun/Moon Tracking, which will set DWARF 3 to track the trails of the Sun/Moon(Moving very slowly to the extent you don't even notice).


3.1.4 Sun Tracking & Shooting

Position DWARF 3 as level as possible.

Wear the ND filters now to protect the sensor from blinding by sunlight. Do not look directly at the sun for we will not take any responsibility for any harm this may cause.

Face the lenses approximately towards the sun, then use dual-lens locating or the joystick to center the sun in the tele photo view.

Switch to the telephoto lens and click auto-focus. DWARF 3 will automatically detect the sun and apply the best settings.

Activate 'Function-Feature-Sun Track'. The camera will calibrate (move itself once, don't panic) and then track the sun.
In tracking mode, the sun remains centered, allowing continuous observation or shooting videos/time-lapses.

During auto-focus, the camera auto-adjusts parameters, if you may know, typically at 1/250s-1/200s exposure, gain at 0, and VIS filter. Do adjust hue and WB as preferred.

Press 'shoot' to take your first sun photo! Refer to this tutorial for Sun Shooting.

*Please note due to the absence of calibration in this process, it is very important to keep the lens cylinder face to the front side(DWARFLAB MARK) while tracking the sun and moon.


3.1.5 Moon Tracking & Shooting

Moon photography is similar to that of the sun except for the need of ND filters, and is best done at night, when it is more visible apparently. 

Level DWARF 3 and aim the lenses approximately at the moon. Use dual-lens locating or the joystick to center the moon in the wide-angle view.
Switch to telephoto lens, click auto-focus, and Dwarf 3 will automatically detect and adjust for the moon.
Activate 'Function-Feature-Moon Track' for continuous moon tracking.

During auto-focus, parameters are automatically set, if you may know, typically at 1/400s-1/250s exposure, gain 0, and VIS filter

Adjust Hue and WB as preferred.

 Press shoot to take your first moon photo! Also, check this tutorial for Moon shooting.


*Please note due to the absence of calibration in this process, it is very important to keep the lens cylinder face to the front side(DWARFLAB MARK) while tracking the sun and moon.


3.2 Video Mode

Video mode functions are exactly the same as those of Photo Mode but for shooting videos.

Follow the steps: target the object, set parameters, select features (if any), and shoot.

*Note: The wide-angle lens can only shoot photos, not videos. When you switch the app to the background or disconnect, the shooting process will still continue.


3.3 Burst Mode

Burst mode in 'Function-Feature' includes a 'Settings' option.Set the time interval (from 1s to 60s) and the number taken of this set of pictures. Note that there's a brief delay in saving photos after hitting stop on taking the burst. So it might take some time for the photos to show up in the album.

*Note: The change of Interval settings during a shooting session will take effect to make sure you get a better record of a whole imaging process saying a totality.

When you switch the app to the background or disconnect, the shooting process will still continue.


3.4 Time lapse Mode

Time lapse in 'Function-Feature' includes a 'Settings' option. 

Settings include "Interval" (time between each shot, ranging from 1s to 60s) and "Duration" (total shooting time, default is unlimited, until your battery runs out).

You can also shoot a time-lapse video using the wide-angle lens, switch to that view and get a record!

An example calculation: a 10-second interval with a 30-minute shooting duration results in 180 frames (1800 seconds / 10 seconds), creating a 6-second video at 30 fps (frames per second). Ignore it if you hate math.

When you switch the app to the background or disconnect, the shooting process will still continue.

Note that there's a brief delay in saving photos after hitting stop on taking the time-lapse video. So it might take some time for the photos to show up in the album.


*Recommended settings for different scenarios:

  • Clouds: 2-5 second intervals for capturing dynamic cloud movements, aiming for a 20-30 minute duration.
  • City Traffic: 1-3 second intervals to capture the hustle of city life, ideally for about an hour during peak times.
  • Blooming Flowers: Longer intervals, like 1 minute, for slower processes such as flowers blooming, extending over several hours or days.


3.5 Panorama Mode

Follow these steps to capture a professional gigapixel panorama!


3.5.1 Locating the Target

Just as above, locate your target in the wide-angle view, then switch to the telephoto view to focus.

*Note: This telephoto view will serve as the center of the final entire panorama.


3.5.2 Selecting the Shooting Range

In the panorama-Function area, you'll find a 'Range' feature. Clicking on it allows you to select the number of shots you want per row or column. The range for rows is 3-30 and for columns is 3-60, meaning you can capture panoramas consisting of 9-1800 photos.*Note: The size of a green frame is taken as one unit. We will add a range preview in future updates. For now, the best is to estimate visually.

3.5.3 Adjusting the Parameter

Both in the day-time and night-time, automatic exposure is suggested, but you can adjust it manually according to your preferences.

3.5.4 Shooting the Panorama

Click on the shoot button to start capturing your panorama arts!*Notes for Panorama photography:

  • During the panoramic shooting, after clicking the shoot button, DWARF 3 will perform a reset operation (AKA, rotate to its limit position) to reset the motor, then rotate back to the first photo in the top left corner of the entire panorama, shooting from left to right, row by row.
  • After clicking the shoot button, there is an approximate 3s waiting time for you, in case you want to attach any filters. 
  • After shooting is complete, the telephoto view indicator (green box) will return to the center of the panorama,as saying, the initial position.
  • In 'Album', the panorama will be displayed as the first shot thumbnail and cannot be downloaded. This means you cannot preview the full panorama on your phone. In the next updates, we will soon add automatic panorama stitching and a preview feature, stay tuned! As for now, you can check this Article: Creating Panoramic Images on a Computer


3.6 Auto Capture Mode

Follow these steps to use DWARF 3 to automatically detect, track, and record birds around you.

3.6.1 Locate the Target

Use the dual-lens system to quickly find and center your target in the telephoto view first.

                                     


3.6.2 Click and Record

Click the capture button, and DWARF will automatically search for birds in its telephoto field of view, recognize their features, and automatically start video taking. It's that simple!
Of course, you can adjust parameters in the Function menu anytime.

  • Note:
    1. When the SD card memory is less than 1GB, recording will automatically stop and save.
    2. When the battery is below 7%, shooting will automatically stop and save.
    3. To achieve the best detection results, you cannot switch shooting modes or manually select tracking objects during the target detection phase. However, you can use the joystick to control the device’s movement or manually focus.
    4. To achieve the best tracking results, you cannot perform operations such as moving the device, focusing, or zooming during automatic tracking and recording.


3.7 Astro Mode

3.7.1 Taking Astro Darks

*Note: Remember, shooting Astro Dark helps prepare for Astrophotography Adventure and ensures better quality images. 

Turn off the lights in Home Page.

Enter shooting interface. Select 'Astro' mode and click "Take Dark Frames Now".

To more accurately reduce noise, the DWARF 3 supports taking personalized dark frames. You can choose to capture dark frames using either wide-angle or telephoto lenses for different use.  

*For optimal results, the dark frame's exposure, gain, binning and shooting temperature should match your actual shooting parameters. If the temperature difference exceeds 8°C, we will prompt you to recapture the dark frame.

How to take dark frames:
  1. Choose whether you need to take Darks for the telephoto or the wide-angle, then switch to that particular view.

  2. At Darks, navigate to Function, then set the Shutter, Gain, and Binning(if you are taking tele darks) of your dark frames to the same settings as your Astro shooting session. The default number of dark frames is set to 10, with support for customization. 

  3. Attach ND filters to the device, and retract the lens into the body facing downwards to prevent light from entering the lens.
  4. Click the shooting button on the right to start capturing the dark frames.
Tap 'Tele Darks/Wide Darks' to see the dark frames you have already taken. DWARF 3 comes with some set of darks which are considered to be highly used.

*Notes:
You can find the parameter sets associated with the dark frames you’ve captured under 'Astro Mode - Parameter Settings - Preset'. Simply click on your preferred parameter set to quickly apply the corresponding settings. Dark frames captured for wide-angle and long-focus lenses will be visible under their respective menus.

3.7.2 One Click GoTo

Open the Atlas, select your target, and click the little camera.Then follow the prompts, DWARF will automatically locate and track the target. For detailed information on the sky atlas, see Section 1.2 of this user manual.

In Auto Model the One Click GoTo will take you right to the target.

3.7.3 Configuring Shooting Settings

After successful tracking, adjust the shutter speed to 15 seconds and above during the parameter setting and wait for the image to update while observing if there is any trailing of the stars. If there is no trailing, you can start taking pictures. If there is trailing, wait for a minute or two until it disappears. Once the star tracking is stable, adjust the gain to ensure that the background is not overexposed.

Select the appropriate filter. For filter details, refer to Section 2.11.2 Parameter Settings in this tutorial.*Notes:
  1. In Astro Mode, after each autofocus or calibration, or when you tap 'end session' after a shooting, the parameters will automatically change to Expo 1s and Gain 120 to obtain a proper brightness for DWARF’s star calculation. Therefore, once locating a celestial object, you will need to manually adjust the parameters.  

  2. The maximum shutter time for both telephoto and wide-angle is 60 seconds.  

  3. Clicking on preset allows you to quickly apply recommended parameter sets. For more details, refer to Section 2.11.2 Parameter Settings and Section 3.7.1 Taking Dark Frames in this tutorial.

*In "Function", switch to the parameter setting tab and set the "Shutter" to 15 seconds and above.

*Adjust the gain to the appropriate value and choose a filter in the same way.

Once the parameters are set, go to the feature section and choose the preferred number of shots based on personal preference. With the AI Enhance feature on, the celestial will show up against a clearer night sky. The remaining options can be left in default settings.

*AI Enhance uses artificial intelligence to detect noise and provide customized algorithm processing for image stretching and noise reduction. 

AI Enhance will not add any synthetic data or AI-generated content to your images.


3.7.4 Shooting & Waiting for Completion

Afterwards, simply click the shooting button to begin taking photos. Once two photos have been taken, the real-time stacked image will begin to appear.
During shooting, you can adjust "Curve" to enhance the colors of the RGB channels and overall brightness of deep space celestial objects. Click the 'Reset' button to return to previous channels.


3.7.5 Manual Astrophotography

If the shooting process fails, click "manual" to proceed with astrophotography manually.
The step is as follows.

We recommend using the manual shooting mode in the following situations:
1. The automatic shooting process fails
2. You want to keep the focus fixed. Manual mode will not perform auto-focusing, allowing the telescope's focus to remain in the same position unless you manually change it.

Select the target from the Atlas, on hitting the camera button, the app will bring you to a page where you need to perform focus and calibration first on your own.

3.7.5.1 Focusing on the Stars

There are two scenarios for focusing - the first time after a firmware update, and subsequent times.

Scenario 1: First time focusing after the update, please use Autofocus. If the image is not sharp, try Autofocus multiple times until a sharp image is obtained.

Click on "Focus" in Astro mode, then select "AUTO" from the pop-up menu of options.At this time AUTO should be highlighted, and the status bar at the bottom will display "Autofocusing in progress", which takes about 1 minute.

Scenario 2: For subsequent focusing, simply tap Infinity Icon to complete focus.


3.7.5.2 Implementing Calibration

Place the DWARF 3 on an open area with the rotation axis in its original position. Point the altitude axis at 45-80 degrees towards the starry sky, avoiding any obstructions to DWARF II's view.
In Astro mode, execute the calibration function. Under normal conditions without clouds or other obstructions, wait a moment and calibration success will be indicated.*Click the "Feature" tab in the "Function" section, then find the "Calibration" function and click "Confirm".

*Please wait for the calibration process to be completed.


3.7.5.3 Start GoTo

Click the Start GoTo button. DWARF 3 will automatically navigate to the target you chose just now in Atlas.

The DWARF 3 will automatically begin calculating the position, pointing to and tracking the star. If you get an image like the one below, congratulations! The tracking was successful! If not, please try repeating this step.

If you want to switch targets, select the next target in the Atlas, click the small camera icon and confirm. Without manually moving the telescope, you can directly click "Start GoTo" without needing to manually refocus or recalibrate.

*Notes for Astrophotography:

  • Ensure DWARF 3's viewing area is unobstructed, with visible stars (no clouds or buildings blocking stars), as these factors may cause Calibration and GoTo failures.
  • Avoid using a filter and adaptor during calibration, as it may cause failure.
  • If acquiring location information fails during calibration, try several more times and check if location permissions are allowed.
  • Pay attention to rotation axis limits during GoTo. Hitting the limit will prevent GoTo from reaching the target. Rotate the DWARF 3 base by a certain angle and recalibrate/GoTo.
  • If you move the DWARF's position after having used the Sky Atlas One Click GoTo Feature (whether successful or not), you should manually calibrate again to refresh the calibration result via hitting Function-Calibration before starting the next session.
  • If the stacked number does not increase when capturing long expo photos:

a. Check if the preview background is too bright at the current gain, try lowering the gain and reshooting.

b. At Expo 1s, Gain 120, check if stars are in focus and minimized. Refocus if needed before reshooting.

c. If the above are correct but stacking still fails, ensure the environment is stable - solid tripod, no/low wind, etc. Then reshoot.

3.7.6 Wide-Angle Astrophotography

Wide-angle astrophotography currently supports manual mode only and requires the telephoto system for tracking. The wide-angle lens, like the telephoto, supports a maximum exposure time of 60 seconds and is equipped with a dark frame capture function (See Section 2.11.2 Parameter Settings and Section 3.7.1 Taking Dark Frame in this tutorial for details).

The following will guide you through how to capture stacked images of the Milky Way using a wide-angle lens. Other features are under continuous development.

How to capture the Milky Way:

  1. Set EQ Mode: We recommend using an exposure time of over 15 seconds, so the first step is to set the device to EQ mode. For details, refer to Section 3.7.2 EQ Mode in this tutorial.

  2. Prepare dark frames: Before starting the capture, click 'Function' - 'Parameter', switch to 'Wide-Angle', and check the dark frame parameter sets to ensure you have the corresponding dark frames. If not, please capture one. See Section 3.7.1 Taking Dark Frame in this tutorial for more details on taking them. 

  3. Select target and track: You may find the proper tracking target with the assistance of Sky Atlas.

Open the following mode in the Sky Atlas (See section 1.2 Sky Atlas in this tutorial), point your phone to the area of the Milky Way you wish to capture and find a target that is approximately in the center.Use the one-click goto function to select the star and begin tracking. 

  1. Switch view: Change the wide-angle view to main perspective.

  2. Configure settings: Adjust the shooting parameters and the number of frames for stacking (or you can take a single shot as well). 

*Notes: Wide-angle only supports 2K resolution photography. 

  1. Start shooting : Press the shooting button to start. 

Below is a demo image for capturing the Milky Way with the parameters: (Shutter 60s * 60 frames, Gain 10).
