An experiment that pays off...sorta

This is a bit of a test that I've had ongoing for a few nights now.
Last night I finally got a chance to try it out.

Nothing new, I simply put my old SLR (film) 80-200mm lens
on to my QHY8 with an adaptor I made on the lathe.
Marc (multiweb) inspired me to try this, he consistently gets
lovely pinpoint stars at these FOVs , albeit with a QHY9 mono, similar
lenses and Ha Filter....but I was mainly after the FOV.

The stars are nice enough shapes 2 stops down from wide open.
The homemade GEM and worm tracked beautifully, all I needed was
for Mr Lovejoy's comet to climb high enough over my roof.....and
the clewds to co-operate.

This is 1hr and 10 mins exposure of part of the tail, stretching almost
to Alpha Cent.
