Hello everyone, I plan to build an electric focuser using a NEMA 17 stepper motor from https://www.skysmotor.co.uk. I have some questions during the selection process and would like to ask for your advice:
1. What is a suitable holding torque for a focuser? Is around 40 N·cm sufficient, or is a higher recommended?
2. Is it necessary to choose a NEMA 17 with a gearbox, or can microstepping drive meet the accuracy requirements?
3. Is there a significant difference in focusing accuracy between a step angle of 1.8° and 0.9°?
4. How can I reduce the impact of vibration and resonance on image quality when operating at low speeds?
5. Are there any special recommendations regarding motor current and heat dissipation in astrophotography environments (low temperature, long-term operation)?
I welcome experienced builders to share their model selections and troubleshooting experiences. Thank you very much! ;other.css('display', ''};fn();setTimeout(fn, 0);">less - Translate

바이낸스 가입 . wrote a new blog entry:39 minutes ago
모바일 환경에서 바이낸스 가입이 인기인 이유
최근에는 PC보다 스마트폰을 이용해 암호화폐 거래를 시작하는 사용자가 크게 증가했습니다. 특히 바이낸스 가입 과정은 모바일 앱에서도 매우 간단하게 진행할 수 있어 초보자에게도 부담이 없습니다. 언제 어디서든 계정을 만들고 거래를 시작할 수 있다는 점이 가장 큰 장점입니다.
