Yes, some of us have been lucky enough to get it all to work by getting the 2" adaptor cut down, but its a close thing. You probably will want to buy an MPCC at some stage Stu - very reasonably priced option to kill off coma - but you can't just screw the MPCC in. Sorting out coma more important than focusers in early days I would suggest. There's a thread here somewhere - options are broadly:

1. Unscrew the piece Mario told you about
2. Cut down 2" adaptor
3. Move the mirror up (longer screws)
4. Cut down the end of the OTA (so mirror is closer)
5. Replace focuser

IMHO its worth persevering, because its a damn hard to get better bang for your buck when your starting out. You will find balance, guiding, wind, focusing a challenge, but its all very do-able with a bit of patience, and you can certainly learn all the important basics of AP to see whether its "for you" before really investing in mounts etc. Options 2-4 would let you use an MPCC.

Let us know how you go Stu
