Thanks guys .
The 10" " Astrograph " is actualy a Meade SN10 and apo flatener , corrector , reducer that gives about 13 micron stars accross the field ( up the typical DSLR ).
I have just put in a Moonlite motorfocuser which works really well and move the Moonlite CR2 on to the 24".
Because of the the fast optics collimation is a bit of a pain but I've got it sorted now.
Be good to see what Scott can do with the image ( and others ) I'm at the bottom of the learning curve
