IC 1396 wide field from the backyard (Las Vegas Bortle 9). This is 45 hours and 15 minutes of exposure, my new record!
This was fun, the framing was really tight but just right with the Meade 70mm APO.

My OIII data looked terrible so I really wish I grabbed that from the desert, but I don't have the will to work on this again so maybe in a couple of years.
