自製步進馬達對焦系統

文章 Kenric Ma » 週六 15 2月, 2014 17:33

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.

Happy to have you back on this forum. A very nice DIY work. Any masterpieces with this Tokina 300mm cannon?

You should have very excellent night sky for astronomy from now on I think, and hope to visit you again soon.

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 Kenric,

With your professional knowledge in electronics, I think that is an very easy job to you.

Do you still have leisure time for astronomy?

Will let you know once I have the plan confirmed, but not in this year.

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

Kenric

Hi Kenric,

I know who he is but never talked with each other, though he was one of the HKAS committees some years ago.

Will you go with him to Lake Tekapo?

Hi LT,

Not this time as he comes with his own group.

If you plan to come to NZ again next year or so, end Feb is a good choice as weather is good and not too cold in South Island.

Cheers

Hi bingsze,

Yes, XR250 came last year and took some really nice photos of star field and Aurora.

Cheers
