This has been my summer project. It is comprised of 19 hours of exposure time. 8 hours of Ha and 3.6666 hours in each colour. It probably needs a lot of luminence data to make it really pop. That said I am really happy with the image.
Great image Paul. The extra luminance data can only further enhance what is otherwise a really successful photo. Are you going to continue with the HA for the extra luminance or use a clear filter ??
Very slick! Good to see you really pushing out the exposure times.. 19hrs is nothing to sneeze at.. Do you find images much easier to process when you have plenty of data? I almost always find the results much easier to attain when going > 8hrs data on a target.
Jeff, I think I am gonna use a clear filter for Luminence. I just want to deal with a noise issue I have at present.
Alex, more data means less noise overall but it takes longer to do everything because of the volume of subs.
Stuart, you may remember that I have one of the early RC models from GSO. In fact I think I was either the second person or third person to buy one in Australia. The scope had a bad baffle design (much worse effects than what you have shown me); so I pulled the baffle out and flocked it with flocking felt. That completely removed the problem. You might want to consider doing that yourself.
I have horrid reflections off Sirius. See the image below. How did you rid yourself of these?
Cheers
Stuart
Try a long dew shade...of at least equal length to the OTA. Also try changing the framing a little. A fraction of a degree can make a world of difference to stray reflections.
Niice image Paul... 
certainly well worth the effort - great detail and the colours are super
