Remote Telescope Observatory - High Resolution Sky Camera

[Raymond TSE]

I have added a high resolution 6M cooled and therefore very low noise Sky Camera inside the Observatory.

看到Raymond的本土遙控天文台日益完善，恭喜!

我經常說建立遙控天文台，結果即拍攝出來的作品固然帶來很大的滿足感，但從夢想到規劃實現，到過程中解決問題並日益完善天文台運作，亦帶來完全不能取代的另一番滿足感。那是購買網上天文望遠鏡服務所不能提供。

用上了冷凍相機做All Sky Cam，夠厲害了

這鏡頭好像不是180度的?

[Raymond TSE]

The lens is full frame Canon EF 8-15mm F4 circular/rectanlinear Fisheye.
The camera is QHY8, as ahown in Nebulosity2.
Thus, the lens is capable of 180 degree cirular fisheye image on APS-C Cmos.

The whole setup is put on top of tripod and placed slightly below the telescope so that I can monitor where the scope is pointing.

If the lens is put higher up for wider FOV, the whole sky could be covered but I could not check the position of the various telescopes.
For now, the scopes' accesssible FOV limited by the roof opening will be enough for present imaging.

There will be another Fujinon fisheye zoom 1.4m-3.1mm F1.4 with automatic iris, to be attached to low resolution uncooled ICX429 chip for outside observatory monitor
of the sky condition. To be erected soon. This video camera GStar2 has senseup but is quite noisy due to some white pixels. Not sure if I could remove these
hot pixels for night time viewing.

你的魚眼鏡相機及鏡頭都很高級

之前有人建議我不如用5D Mark II配你那枝鏡頭做西藏全天魚眼鏡，我倒不捨得的....

開玩笑，若你那枝鏡1月底至2月初香港初春濃霧之際沒發揮，我很樂意幫你帶到阿拉斯加拍極光

在站內監察，我在西藏是用一個IP Cam的，當然那個在圓頂外的魚眼鏡，也能能幫手看看圓頂的運作，又或者有沒有積雪等其他問題。
