Re: M81-82 with AP CCDT67

Robert, there is a prominent double right at the edge of M81 and it is well resolved in your image. Maybe that threw you off? I really think you did a great job on this one.

Thanks Roland. I saw a few slight football shapes in the image but looking back I am wondering if those are actually double stars stacked on top of each other.

That's a very good image. I don't see where the stars are messed up at all.

I just started using an 8 inch RC and tried the CCDT67 on it.  I spaced it for 67% bringing the f/8 1620mm scope to F/5.3 1075mm.  I really like it and it ends up acting as a flattener to some degree.  My guiding wasn’t great so all stars are a little messed up but I think I am going to keep the CCDT67 in most of the time.  I like shooting at f/5.3 more than f/8.  My other scope is an FSQ-106 so I like using around f/5.
