Re: DSO 遺照集 -- M72 with planetary cam

92. M72

Taken with DIY 30cm F4 Newtonian + 462C @YL last night @1200mm F4
69x10s, unguided with Vixen AXJ mount (31 frames rejected to stack up by DSS)
Stacked in DSS with darks calibrated only
Processed in PI and PS

When it was taken, it was very low above west horizon, no more than 30 degrees. Moreover, very very poor seeing condition. So, no quality, just a record I had taken it in HK.

Re: DSO 遺照集 -- NGC253 with planetary cam

93. NGC253

Taken with DIY 6"F5 Newtonian + 462C @YL at 20201116 @750mm F5
100x20s, unguided with Vixen AXJ mount
Stacked in DSS with darks calibrated only
Processed in PI and PS

When it was taken, it was very low above west horizon, no more than 30 degrees. Moreover, very poor seeing condition, low transparency and much LED light pollution at my site. So, no quality, just a record I had taken it in HK.
