DSO 遺照集 -- NGC7000
Re: DSO 遺照集 -- NGC281 with 6"F4 newtonian from PTC
37. NGC281
Taken with 6" F4 Newtonian + MPCC3 + LPS + 100Da @PTC in 2016 @600mm F4
31x240s @iso800, autoguided with Vixen SX2 mount
By comparing to the one taken with 6" F5 + 300Da, seemed there was not much improvement on the detail captured, though longer exposure had been attempted.

Re: DSO 遺照集 -- M45 with 100Da
40. M42 taken with 6" F5 newtonian and 100Da
Taken with 6"F5 Newtonian + MPCC (for film) + LPS + 100Da @PTC in 2013 @750mm F5
9x240s @iso800, autoguided with Vixen SXD mount
By comparing with the one taken with 300Da, maybe you can see something different in resolution.

Re: DSO 遺照集 -- M57
41. M57
Taken with VC200L + reducer + LPS + 100Da @ PTC in 2015 @1280mm F6.4
3x240s @iso400, autoguided with Vixen SX2 mount
Calibrated with bias only in DSS
The OTA will be modified soon so as to improve the star image and diffraction issue happening on those bright stars.

42. M45 from PTC with 6" F4 Newtonian
Taken with DIY 6" F4 Newtonian + MPCC3 + LPS + 100Da @PTC in 2016 @600mm F4
13x240s @iso800, autoguided with Vixen SX2 mount
Maybe the best M45 image from PTC ever I have taken with DSLRs up to now.
