How to Deal With Calibration Failure

This guide provides a step-by-step checklist to resolve calibration failures on DWARF II. Follow these tips to ensure successful calibration.

1. Common Causes of Calibration Failure

1. Using Filters:

   • Do not use any filters during calibration or when performing GoTo. Attach the UHC filter only before pressing the shoot button.

2. Lack of Well-Focused Stars:

   • Ensure there are well-focused stars visible in the sky.
   • Refer to: "DWARF 2 User Manual" for focus tips.

3. Obstructions in the Environment:

   • Perform calibration in an open space without obstacles like buildings, trees, or clouds.
   • A clear sky is essential for capturing stars.

4. Mount Position Limits:

   • If DWARF II reaches its movement limit during calibration, manually rotate the mount, recalibrate, and try GoTo again.

5. SD Card Storage:

   • Ensure there is enough free space on the SD card, as full storage can disrupt calibration.

2. Calibration Process Overview

• During calibration:

  1. The scope moves to its start position (lens tilts slightly upward).
  2. It returns to the position where the calibration command was initiated.
  3. The bottom axis rotates 5 degrees left, then 5 degrees right.
  4. If it doesn’t capture stars after 3 rotations, it rotates 20 degrees to search for stars.

• Space Requirements:

  • Tilt the scope 45-80 degrees vertically.
  • Ensure at least 10 degrees of horizontal clearance on both sides.

3. GPS Issues

• If GPS Fails to Obtain Location:

  1. Verify GPS permissions are enabled for the DWARFLAB app:
     • Search "Location" or "GPS" in your device settings and allow DWARFLAB to access location.
  2. If GPS still fails (e.g., in remote areas with no Internet):
     • Manually input longitude and latitude in the DWARFLAB app:
       • Go to Settings > Location in the app.

• Refer to: "DWARF 2 User Manual-DWARFLAB helpcenter" for more details.

4. Additional Notes

• Clear Sky Requirement:

  • Calibration requires a clear view of the sky. If the calibration fails repeatedly, ensure there are no obstructions or clouds.

• Restart Calibration:

  • If the above steps don’t work, restart DWARF II, adjust its position, and try again.
• Contact support@dwarflab.com if you can't figure out the problem.
