DSO 遺照集 -- NGC7000
Re: DSO 遺照集 -- M42 with 6" F4 newtonian
101. M42 again
Taken with DIY 6" F4 Newtonian + Vixen corrector PH + LPS + 100Da @YL at 20210203 @570mm F3.8
27x120s @iso400, autoguided with Vixen AXJ mount
Stacked in DSS with darks and a bad flat calibrated
Processed in PI and PS
Also attach one light frame for your reference. Just a test to see the star quality corrected by Vixen corrector PH and for back focus adjustment with 1600MM imaging gears.

Re: DSO 遺照集 -- IC410 in Ha channel
102. IC410
Taken with Vixen R200SS + corrector PH + 1600MM @YL in 2018 @760mm F3.8
Ha = 8x360s, autoguided
Stacked in DSS with dark calibrated only
Processed in PI and PS

Re: DSO 遺照集 -- Monkey in Ha channel
103. Monkey nebula in Ha channel of 7nm vs 35nm
Once took this object with Vixen R200SS in Ha channel @7nm some years ago in YL. Last night, imaged it again with a DIY 6" F4 Newtonian in Ha channel but @35nm bandwidth. Unfair to compare them, but maybe there is still something worthy for taking a look.

104. M42 in Ha channel
Taken with DIY 6" F4 Newtonian + Vixen corrector PH + 1600MM @YL at 20210215 @570mm F3.8
Total integration time = 3x600s, 5x120s and 5x60s in Ha @7nm
Stacked in DSS with darks calibrated only
Pre-processed in PI and combined in PS using layers for HDR effect
A test to see if my DIY adapter for coupling 1600MM onto Vixen corrector PH works flawlessly. Luckily I made it this time.

Re: DSO 遺照集 -- M35 taken in YL
105. M35
Taken with DIY 6" F4 Newtonian + Vixen corrector PH + LPS + 100Da @YL on last Wednesday @570mm F3.8
30x90s @iso400, autoguided
Stacked in DSS with dark and flat calibrated
Processed in PI
A test to see the star qualtiy on an APS-C sensor.

Re: DSO 遺照集 -- M42 cropped
106. M42 cropped
That is a crop from a FF image taken with 5Da, and aybe one of the deepest image of M42 taken by me ever in Hong Kong with DSLRs.
Taken with Vixen VSD100F3.8 astrograph + reducer + LPS + 5Da in Lantau Island in 2015 @300mm F3
23x180s @iso800, autoguided with Vixen GP2 photoguider in RA direction only
By the end of this year, I will re-visit M42 with my DIY 6" F4 Newtonian in Hong Kong and have confidence that I can have better result than this one with cooled CMOS camera.
Single light frame for reference
