Hi all:
Here is M27 taken with a TEC APO 140, Starlight Express SXV-H9, G-11 mount and Astrodon filters. The nebula itself is Ha (R) and OIII (GB). The background stars are regular LRGB. I merged the images using Photoshop's layers functionality. It seemed to work pretty well.
2.5 hours each of Ha and OIII, (30 minute subs) About 1.5 hours total for LRGB.
I hope you like it! Jim
