Description

M 92 as seen in a hot summer night. Maybe i could have collect more lights, but i was so tired i decided to stop at about 1 o'clock and go to bed.

I uploaded two different versions. Original with a masked stretch and B) with a manual stretch. All other processing steps are similar.

There is a more advanced process described by Pat Rodgers ( https://www.astrobin.com/297509/D/?image_list_page=2&nc ) to stretch globular clusters even better. When i have the time i will try this process.

Also this is the first time i used 0 gain. I am surprised how bright the cluster is with this low gain setting. But the stars are not burned out, so i think this setting might be the right choice for brighter objects.
