Please let me know if you have any requests. It works as described. ### 2/5 — No way to calibrate *2024-09-06* I’d like to be able to reduce the error in the direction to less than 3 degrees. I see no way to calibrate. I really like the idea of the simple arrow and ability to point in a specific direction, but 19 degrees of error is huge, with no way to correct it. **Developer response:** Thank you for your review. Please let me know if you have any requests. Calibrate it yourself. ### 5/5 — Astrology use *2023-11-04* Easy true North for telescope alignment. **Developer response:** Thank you for your review.
