Hi,As well as lunar imaging with colour and mono webcams, I also use my Canon EOS 500D on my 20cm f/20 Mak-Cass ‘scope.Likewise, I use mirror lock and the self-timer delay. The mount is driven at lunar rate, I carefully align and focus on an area of interest using Live View, then I take up to 30 shots with the self-timer option, pausing a few seconds between each shot, to allow vibrations to die down.BMPs are then stacked and processed via Registax.An example is given on page 15 of the 2011 May Lunar Section Circular. (This is just a small crop from the original.)It’s nice to work with large images instead of 640×480 pixels from some webcams. I occasionally add my Apo Barlow lens (with T-mount) to increase the magnification.Clear skies, Alex.
