Cresent Nebula I decided to try out my OIII clip in filter for my Canon 40D this is a total of 10 hrs 5 hrs OIII and 5hrs HA both Astronomik 13nm filters after alot of time combining and playing around I decided the OIII needs alot more time maybe 10 hrs on its own so I combined HA for Red and OIII for Green and Blue processed in Registar and CS2
Thanks Les
