I am looking forward to beginning imaging again with construction on my new observatory starting very soon.

Technology and processing has moved one significantly... Cmos has really improved imaging...the shear volume of frames means less influence through seeing...easy to reject the odd really bad frame and the modern stacking algorithms with their very powerful rejection methods basically bringing out of range pixel values back into range based on the average...
I have a (very clever) friend doing some measurements at the moment based on our systems in Spain....so far the signal to noise is favouring the shorter subs....He still hasn't finished his findings but on the one pier we have assigned there are early indications that just less than 1hr of 30s subs gives the same as 3hrs of 180s subs....its actually incredible....the big down side is that the time it takes to dither and the storage of huge numbers of frames, not to mention the processing power needed....there still lots to do with it including variable signal strengths etc.... cant wait to see the whole findings
