Re: DSO 遺照集 -- M33

文章 LT » 週四 28 12月, 2023 00:22

168. M33
A combination of L data taken at the beginning of this month this year and RGB data taken in 2018

L data:
35x300s with flat, dark and bias calibrated in PI, Bortle 7-8
Vixen SD115S apo refractor + HD flattener + 1600MM @PTC @908mm F7.9
Autoguided with SXD2 mount

RGB data:
R=B=G=8x300s captured in 2 different nights in 2018, with flat, dark and bias calibrated in PI, Bortle 7
Vixen SD103S apo refractor + HD flattener + 1600MM @PTC @814mm F7.9
Autoguided with AXJ mount

All were processed in PI and final touch in PS

Very unfortunately, a serious tragedy happened on the EWF mini with my trip to PTC in December. The G filter was dettached from the housing position and dropped to the top of the L filter by covering about 1/5 area. I didn't note it until I took the flat in other days. I just found why the mater light appeared so weired after applying STF
