ahhh... in that case I would strongly advise putting automapper to the side and working on plate solves - just getting used to what works and what doesn't, etc. Then put automapper back in the equation.
I've got a 6.3 reducer on my scope which takes it down to F/7.5 in reality, focal length of 2180mm .. and it's hard at that focal length. I expect you'll end up buying a focal reducer, but then I guess you have such a large chip you might need to stay at F/10 to get full coverage? Hmm, tricky maybe?
I can't remember the database names of ones I have off the top of my head now, been a little while... if I have it at home I might be able to send you it on a CD.
People kept telling me I should be able to plate solve with my setup 100% the time if I have the right database. Wrong. Fact is, with my FOV (and perhaps yours) there are often only 3-10 stars brighter than mag 18ish ... it's not reasonable to expect that to plate solve. Of course some times there's 60 stars, but all depends on where you're looking in the sky.
There's a few settings hidden away in CCDSoft and TheSky6 that might need tweaking too, to ensure that all the stars you do have in your databases are being made available for plate solves. I can't remember them right now but might be able to find them for you if you continue to have problems.
