自製步進馬達對焦系統
自製步進馬達對焦系統
為自家天文台進行遙控化時, 在網上發掘了一個很值得製作的電動對焦系統叫Sharpsky Focuser.
這系統的特點是ASCOM兼容, 可精確控制對焦位置, 具備溫度補償, 可予設不同濾鏡的焦點位置, 可手動控制等等...
有興趣可到 http://www.dt-space.co.uk/SharpSky/ 下蛓線路圖及相關firmware.
溫度補償部份可到http://www.dt-space.co.uk/SharpSky_TC/ 下蛓
ASCOM Client 軟件可到http://dt-space.co.uk/SharpSkyClient/ 下蛓.
這系統本來有套件出售, 可惜已經賣完, 只能按照線路製作.
設計者現正出售一個商業版, 另可同時控制四組除露發熱線. 有興趣可到http://www.sharpsky.net/ 查看.

Hi LT,
This lens has been put aside for a long time and now I want to make better use of it. It is a very good lens but requires very accurate focusing especially at F2.8. That's why I have to build a high precision focusing system for it. Temperature compensation is also a must due to the tight focusing tolerance. I don't want to spend thousands of $US to buy a TCF and luckily I came across this project.
BTW, you are always welcome. Next time when you come, we shall go imaging together.
Cheers
Kenric

Hi LT,
The designer did a very good job in documenting the project plus lots of YouTube illustrations so it makes the job much easier.
I can arrange my schedule to go with you for a few days if you let me in advance.
Btw, Huey Pang of Astrolink is coming this Sunday to visit me then go to Lake Tekapo. Do you know him?
Cheers
