為何200mm AstroTrac都拉線?

[LT]

600mm 盲跟很考追星儀的能力！可能7cm F6的望遠鏡拍出來的影像質素比這支zoom tele會好一些呢！

為何200mm AstroTrac都拉線?

我還未查明原因

再加上 Optolong external UHC filter, 看看能不能見到 Sh2-240, 曝光加到 7 分鍾，都係比較困難，因雲來了曝光不夠，還是一定看不到? 下次都係要找個 Ha filter 試試
Canon 600D mod
Canon 100mm@F3.2
iso1600, 7min x 7, dark, flat, bias
filter: IDAS LPS-D1 + Optolong external UHC filter

換了波頭，曝光穩定了

廣域星野內有星雲, 別有一番滋味。好圖
