I was setup by 3pm yesterday ready for some unguided imaging of M42. Kids and wife we're all asleep by 11pm, had the mount reasonably well aligned for 2min exposures with stars landing bang in the middle of a 9mm plossl....
....Put on the Bahtinov mask and attach the Canon to the ED80, only to find that the extension tube is too long and I couldn't reach foucs and then remember that my lower profile adaptor is on the 8" Newt at a mate's place 60km away!!!!

I was sooooooooo looking forward to actually collecting some data last night, only to be pipped at the post by our mate Murphy.
As a consolation, M42 was brilliant in a 20mm, and 47 Tuc was stunning.
I'll get this imaging thing sorted one day......
