Veil - OIII only, test shot

Still learning how best to use the EQ6. Test shot of Veil nebula with Canon 600D (unmodified) and 70-300L lens at 300mm f/5.6. Astronomik OIII 12nm filter. 7x 8m subs.

    Hi GlassWalker,

    Looks like the new mount is going to be a success. Was this just "lights" or have you already had a chance to grab some 8m darks? My own experience with banding (induced by the CCD's RBI flood infra-red LEDs) is that with enough (15 in my case) high quality darks the processing can go deeper. Difficult to achieve with a sensor that isn't temperature controlled, of course!

    Good to see you putting that OIII filter to work. The window between sunset and moonrise is still too narrow for me to do any deep sky imaging. :(
