Nice image! 那些暗雲的層次感就是我要拍的目標，不過12月的台灣之旅告吹了，要麼二月份在西藏再來，要麼三月份到台灣拍。

很久沒有正式用雙晶片系列的ST系相機拍了，但Ben能否用內置導星晶片找到導星? 按理就算用上顏色濾鏡也不太難? 下面是我模擬的圖像，顯示星等才10等而已

另外我最近做一個實驗，不用L，只用RGB延長曝光間去拍.....

I didn't use the onbroad guiding chip as my GPD cannot support the autoguide by ST2000XM. The DD1 control does not have relay.

I think it is possible to find a guide star for 1-2 s exposure.

no, I used Vixen GP mount in 90's.

Even a similar old style hand control (non-goto version) from Sky Watcher can be modified to accept ST4 signal - just connect the ground and 4 directions.

I like the color. The detal is higher than that of taken by DSLR.

I agree with you, Even though the CCD is ST-2000!
