M27 - The Dumbell Nebula

This is really just a combination of oIII and Ha subs. I used a cls filter for the background stars since at the time I didn't know how to create a synthetic green channel.

Date: 3rd June.

Scope: Nexstar 8" with fastar lens on a Celestron HD wedge.

30x60 secs Ha and OIII and 20x30 secs CLS.

Captured and individual channels combined in ImagesPlus. Combined and final processing in Photoshop.
