As for the stars it seems as though coma is evident as you say around the edges but it appears as though the stars around the middle areas may be ever so slightly elongated too which points to tracking not being 100%. It's always hard if you're not guiding and 60sec subs will definitely show up any drift.
What scope are you using and I'd be interested also in the coma corrector you have. I'm getting mine today and I'm ready for the usual issues I hear about spacing etc to get it right. I'm using a DSLR so setup will be different to yours.
Have you followed the prescribed offsets for your camera?

Hey anth, I've got a GSO corrector (same as the bintel one I believe) which from memory requires a 80mm spacing....however I'm at around the 76mm mark due to not having the appropriate spacers. It made a noticeable difference to the pics overall. I don't think you'll be disappointed with putting one in. I guess my only advice is try and use as few spacers as possible to make up the required distance......less spacers = less opportunity for those minor errors that cause us issues.
Scope - this is from a GSO 200mm F4....not bad for something I picked up cheap off here.
As for this pic of mine....I didn't go through the 90 odd subs as it was a very quick stack before work this morning. Maybe I do have a dodgy sub or two in there. However....I was guiding last night and have been getting less than 1 pixel variation on PHD....I actually did a few 10 minute subs the other nighty on another target with minimal issue. I'll have another look through them tonight and see if I can track down the issue/s.
You and Mickoid should make some plans to come up......I can now set you up inside the obs rather than on those slabs outside....saves wind deflection!
