Haven't posted much for a while, had some issues with my refractor last year and last night I took it out for its first test run since repairs. Apart from the fact that I didn't focus it for 5 hours (so about four hours of out of focus subs), I'm really happy with the result.
Recently bought a second hand Nikon D810 so I thought I'd give it its first light. For some reason Windows 10 on my MacBook Pro doesn't talk to my D7200 or D810 (need to do some more fiddling) so I dusted off my old ASUS laptop and used it for mount/camera control.
Forgot how short the USB cable for the D810 was so I could point the telescope south with the laptop sitting right under the camera... And that's about it. Wanted to photograph something so I just picked any nebula that would transit meridian at 4am (when I was going to start packing up) and that just happened to be NGC 3199. Not one I've really heard of nor seen before, not too far away from NGC 3372.

58x300s at ISO800 but not dithered, for whatever reason the laptop kept crashing when a dither command was sent from MaximDL so I just turned dithering off.
Sleep was more important so I focused at 10:50 and that was it! I know I SHOULD refocus every hour with this scope but I was snoozin.
Was reasonably windy for the first few hours but I have no idea if that affected anything, early subs didn't seem wind affected, later ones were just out of focus :P
No noise reduction, no deconvolution, just stretched and played with some curves before saturating the hell out of it :P
