I've recently acquired an STL-11000M (class 2 chip was not much more than half the price of a class 1 camera) and this is my first attempt at tri-colour imaging. The STL is intended for a larger telescope I am building, but in the meantime I have tried to use it on my 200mm scope with just a 2" Moonlite focuser and Paracorr. Unfortunately, the 2" focuser isn't really up to the weight and flexes a bit (esp near the meridian). To compensate for the weight I have rigged up an high tech adjustable anti-gravity device (see attached image) which helps keep the flexure in check.
Anyway this is a 6hr:50m (L+Ha)(R+Ha)GB image (yep - dived in boots and all). I gave substantial weight to the Ha which has given a fairly red interpretation. I'm not totally happy with the stars as I found it quite challenging to remove the halos. Anyway, got some good tips from Marcus (marc4darkskies) to get me going in photoshop, but really still a bit of a novice. The focus was a little soft as I found the Paracorr did not yield a flat field, due I think to the Paracorr / CCD distance (it seems to be more critical than the specs say). I will be doing some tests later to determine the optimal spacing.
