DSO 遺照集 -- NGC7000
Re: DSO 遺照集 -- A tiny galaxy adjacent to M3
Besides very heavy light pollution, transparency was poor too . So it is really a big suprise to me that the tiny galaxy could be captured at my observing place with so short exposure.

Re: DSO 遺照集 -- M27 stack of 2 sets of data from 2 nights
60. M27 (stack of 2 sets of data from 2 nights)
Both sets of data were taken with Vixen AX103S astrograph + LPS + 40Da @824mm F8
13x180s @iso1600 from PTC in 2013
28x180s @iso1600 from YL in 2013
Stacked in DSS and processed in PS
That should be one of my best M27 images taken with a 4" scope in Hong Kong.
