Re: DSO 遺照集 -- M17 taken with VC and 5Da
46. M17
Taken with VC200L + reducer + LPS + 5Da @PTC in 2015 in 2 nights @1280mm F6.4
4x240s @iso800 + 8x360s @iso500, autoguided with Vixen SX2 mount
Calibrated with darks only in DSS
Maybe that is the best image from PTC taken with DSLRs by me up to now.

Re: DSO 遺照集 -- M20 taken with VC and 5Da
47. M20
That should be my best image from PTC ever taken with DSLRs up to now.
Taken with Vixen VC200L + reducer + LPS + 5Da @PTC in 2015 @1280mm F6.4
14x240s @iso800, autoguided with Vixen SX2 mount
Calibrated with darks only in DSS
This DSO had posted on this forum before. But this time it was re-processed again by stacking the subs in DSS instead of PI and no PCC applied in PI as well.

Re: DSO 遺照集 -- M8 from PTC with DED108SS
48. M8
Taken with Vixen film astrograph DED108SS + LPS + 40Da @PTC in 2011 @540mm F5
18x210s @iso800, autoguided with SXD mount
Calibrated with darks only in DSS
A little bit out of focus, autoguiding not so good........
Moreover, this old astrograph worked quite good to films, expecially for 67 format. However, failed to digital sensors, especially for small pixel sensors.
