I guess I sohuld have known better - badly impacted by light pollution and an unmodded Canon 20d - but I had a go. This has come out blue/green due to the light pollution and lack of Ha sensitivity and I had to clip to get rid of the worst of the orange glow. I really want to do this again from a dark site.
It is 30 3mins, iso 800, ICNR on, Canon 20d and a WO66SD with a WOFlat2, overall fl 312mm on a G11.
Calibrated and stacked in IP then levels in PS Elements...
