First Light Images for a new Astro-Tech AT60ED telescope. Nice 360mm F/6 doublet with FPL-53 synthetic fluorite and Lanthanum lenses. I bought the 0.8x Reducer/Flattener that goes with it, too. It gives you a 288mm F.L. at F/4.8 with that combo. Resolution is still good at 1.72 arc sec/pixel with my camera.
These objects are the Eagle Nebula, Trifid and North America Nebulae. All were taken with a QHY183C camera at gain 20, -15C cooling and a cheap no-name UHC filter from a metro area, Bortle 7-8 zone.
Not too bad for a session from the metro LP zone! Only 96 minutes, but it was enough with these settings to show quite a bit of nebulousity. I used the unity gain setting (11) and that made a big difference in hot pixels and noise. My other shots at a gain of 20 were plagued by hot pixels that SharpCap 3.2 doesn’t seem to be able to deal with very well. I like this much better and there is just as much data buried in there as in the higher gain shots.
