This is first light on my new SharpStar 150mm f/2.8 reflector. Here's about 20 minutes of processing. I did crop some because I have a gradient on one side I can't seem to eliminate, most likely from people coming up the road with their brights on, and with this being fairly low it hurt. I do need to find a place where I can get some 1 or 2mm M48 spacers because I think I was a few mm off from the 55mm backspacing this scope requires. There were also some high wispy clouds, but I wanted to get first light after having ti for a month.
