My astrophotography efforts starting back in 2003 with fairly primitive equipment up to the present.

Adjust your monitor's constrast and brightness so that you can see all 17 shades.

M13 Globular Cluster

June 27 08_AP140 F7.5 3x2.5min 10 darks Canon 350mod (Poor autoguiding reduced image quality)

Separation of SAO 65508 (at 12 o'clock) and SAO 65481 (at 7 o'clock) is 30'23",
so the 350 thru the AP140 gives about 48' x 72' of coverage, or 64' x 96' with the .75 telecompressor.

M92 globular cluster

Aug 19, 2016 C9.25 Canon Rebel SL1 best 13 of 104, 1min ISO1600
This cluster contains roughly 50,000 to 100,000 stars. These stars formed together and are gravitationally bound.
Stars orbit the center of the cluster, and the cluster orbits the center of our Galaxy.
About 160 globular clusters are known to exist in a roughly spherical halo around the galactic center.
