well i knew you were experienced so i spose 7.75 is possible.
the engineering in Dave's Dodgy Dobs means that sometimes the guiding will stick and a small shudder can run thru the optics.
i am trying to track that crud down. i have triied cleaning the televue (scary) and a few goes at cleaning the ccd. I will rotate the powermate tonight and see if the spot has rotated with it?
Wow John, that's an amazing result.
David you've done very well with this avi.
I wish you two were able to come to Lostock.
We would've had a blast........and scare off all the wild life, in the process.
No not yet, although I'm so snowed under at the moment processing all the Lostock images.
I'll have some more to post soon.
Looking forward to getting your avi's David.
