ZEq25開光 [蔥寶恭喜樣]

沒有autoguide 150mm 一分鐘追蹤似乎沒有問題。

色可以再調調

但這不是茶壺蓋, 是茶壼柄的其中三顆星。圖中除了超小型(1.6角分)的M54球狀星團外, 沒有什麼深空天體(人馬座矮星系很難拍得到)。圖中的; Pelag = Nunki = sigma Sgr; Astsella = Ascella = Askela = zeta Sgr

ZEq25有Goto, 應選茶壺頂星Kaus Borealis(lambda Sgr), 或茶壺蓋底的Phi Sgr或delta Sgr。但那裡也沒有什麼深空... M8(礁湖星雲)在茶壺蓋頂約五度半。

用PixInsight內的annotate image做。

出多幅位置參考:

But can't find or do the image annotate!
Any suggestions? Thanks.

After this, go to SCRIPT -- Render -- AnnotateImage.
