some very deep Hydrogen Alpha images

I got out the 6 inch Meade "Cometracker" schmidt Newtonian and did some Ha imaging seeing the moon was present. I went quite deep, going 20 mins each exposure.
first one is RCW75, just east of Crux, 3x 20 mins (1 hour total time)
2nd is ngc 6537 2x 20 mins
3rd one is the Lagoon, only round 700 seconds before high cloud forced me to cut short the exposure.
4th (actually taken before the Lagoon shot) is NGC 6188 in Norma

All shots with baader 7 Nm Ha filter, and MPCC coma corrector, with modded 350D camera
