Description

NGC 7822 - Molecular clouds, ionized Hydrogen and Oxygen are shaped by intensely bright and young stars including one of the hottest known stars, BD+66 1673, an O5V with a temperature of 45,000 K and a luminosity 100,000 times that of the Sun. NGC 7822 - Wikipedia.  The region is approximately 3,000 light years from Earth.

A couple firsts for me on this project:
1. New imaging location.  The new location is a Bortle 4.5 light pollution rated area with much lower regional light pollution than my typical Bortle 7.  Bortle scale - Wikipedia. Most of my image integration sessions will originate from this location, moving forward, because it's simply easier and faster to collect data on deep sky objects from a darker location.  Another bonus is the new location has less atmospheric turbulence as it's farther away from mountains and the airflow crosses a major body of water before travelling overhead so the seeing should be better and more consistent, again making for easier imaging sessions.
2. ZWO AM3 mount - New mount thats super light and pairs nicely with my Askar FRA300 60mm telescope.  I can easily pickup the entire telescope, mount, tripod and carry it outside and be up and running in minutes.  Polar alignment is a little tricky with the tiny knobs, but certainly manageable in a reasonable amount of time.  I'm seeing sub .5" guiding on a consistent basis, which is awesome.
