Since I had this screen open for the last message thought I would share my latest image courtesy of my 1100. 

This is SH2-308, the Dolphin Nebula, at 540mm with an ASI6200, about 35 hours combined of Oiii and Ha (it has little Sii), as R=Ha, G=(2*Ha+Oiii)/3, B=Oiii, with a lot of stars removed and de-emphasized. 

Any not-round stars are from optics, not the mount.  :)  

Criticism and suggestions welcomed.
