The result was a HUGE image mosaic of stars smearing across my computer screen. I cropped the file down to the least smeared patch and ran it through Astrometry.net, which helped me identify 6 Messier objects all in the same image. The large image is below, sliced into smaller pieces as identified by the white boxes.
|6 Com region of the sky, 4 min 22 sec total exposure time, stack of 197 subs, 71 dark, 53 bias|
300mm, ISO 6400, f/5.6, 1.3 sec each
|M86 and M84|
|M88 and M100|
|M99 the Pin-Wheel Nebula, and M98 (just barely).|
This haul brings my Messier total to 62 out of 110!
