M13
I've imaged M13 in Hercules before. This Globular Cluster is bright enough that it is one of the few Messier objects I was able to track down visually through a small telescope from my suburban yard. This makes it a fat target for astro-imaging. This is "first light" for a new field flattener that enables me to get pretty, round stars all across the image field. Click into the image to confirm that it's working nicely. When you do, take note of the small smudge above and to the left of the cluster -- that's galaxy NGC 6207, 30 millon light years away (compared with M13 just across the street at 22,000 ly).
Tech Stuff: Borg 71FL/Borg 1.08X MultiFlattener/ZWO ASI1600MC cam/IDAS LPS-D2 filter/iOptron CubePro 8200 mount unguided/56 minutes total exposure time using 8 second exposures captured with SharpCap Pro/processed with PixInsight, GIMP and ACDSee. SQM-L reading about 18.7. From my yard 10 miles north of New York City March 27, 2019.
