Thanks Paul,
My subframes were 900 seconds. Sub frame length is depedant on a few things. My good friend John Smith and done some interesting work about it. Good reading here...

What was your sub lengths Ken? I am trying to get my head around this for galaxy work with the RC8 and the QSI. I did some Ha subs on M83 over the weekend at 15 minutes and thought it was ok but I could have devoted longer sub lengths. Any thoughts on sub length with 1600mm plus focal length?
