This man has converted the vesta camera into a deepsky CCD camera !
For me he is a genius, and every one who build this MOD should carefully respect his wishes, see the website for details.
Steve you are the man who did it !
All details to complete the "mod" are given on his website http://home.clara.net/smunch/wvest1.htm
I wanted to give a very little contribution to this camera, in the simple form on some advices:
With your vesta MOD1 .. your certainly do a better picture than this firstlight.
The image is not so good
because of a major default of the 45° miror, i used a 70/350
refractor for tests.
But the camera works very fine !
If you have bad tracking on your scope, meade DS, ETX ... just put the cam on telephoto lens, i use to track for 30/40 seconds at 135 mm focal lenght piggypacked on a meade DS telescope.
This focal is enough to catch lot of objects M31,M42,M8, ...
