I'm still thinking about photometry and a can do it with the ST402 ( still haven't bought it ) and my C9.25 but now I'm considering something else.
I have done in the past photometry with my DSLR especially on Eps Aur ( for Jeff Hopkins). Actually I like to do measurements of variables which are currently in the picture. For now the SN in Lac, R CrB, Z UMi etc...
Instead of always doing timings ( which I have done in the past ) I think that I better concentrate on the previous mentioned stars. I think there is no need to buy a CCD en V-filter because I have a Canon 40D and it's perfect for V-measurements via the green channel.
I also going to sell my C9.25 and buy a 8 or 10" f/4 photonewton. With the DSLR and a shorter focal length there is no need for a laptop and guiding.
Any thoughts on this?

Since you have already participated in the Eps Aur campaign and have explored DSLR photometry you already know the potential for this sort of photometery better than I do. Having read a bit about it and having seen AAVSO interest growing in DSLR photometic potential, I think you should "go for it."
Re scopes: No advice from me either way.
Good photon collecting!

Only after defocusing the image during capture did my result fall within expected limits.
