15 panels of the planned 20 panel mosaic down, shot with an ASI183mm and Samyang 135mm lens on a Sky Watcher AZ-GTi mount, ZWO EAF used for autofocus, Each panel is 20x3' subs at gain 111 and offset 11. I have about 3.5 more panels to finish for the h-alpha portion to be complete, then I'll start the Oiii, hope that Oiii done by the end of the October (fingers crossed for more clear nights!). I need to go back and redo some of the panels background extraction/stretch, but it's coming together quite nicely so far. Seeing was awful last night so a few of the panels have poor stars, but at such high resolution it's not immediately noticeable.
I've been working on this one for a while, shot with a ASI183mm and WO GT81 on a belt modified Sirius EQ-G from our home in Bortle 5/6 skies near Salt Lake City. This is a LRGB combination: 40 x 1 minute at Gain 53 for each RGB 140 x 1 minute at Gain 53 for Luminance Learning that RGB and LRGB combination with a monochrome camera is still a very difficult thing to get right, this target is about at the limit of my setup's resolving power in terms of decent detail, still a fun and challenging one to try out!
Definitely the hardest object I've ever attempted to image, this is a reflection nebula buried in dust. From my bortle 5/6 location it takes a huge amount of integration to pull detail out from the background. This is a beautiful blue target, reminds me of the Pleiades in terms of colors, with dark dusty clouds that obscure stars in the background. Shot with an ASI183mm on a William Optics GT81 with a Sirius EQ-G mount, using ZWO LRGB filters. All subs done at gain 53 and offset 11: 211 x 120" for L 125 x 120" for each RGB.
