Just tried out my new 1100D at prime focus thru my 4SE’s optical port in alt-az mode. I captured 90 frames (each 20s x ISO6400) using Canon EOS Utilities and then used AstroKam to filter them down to 56 good frames. DeepSkyStacker did its stacking magic and then Star Tools brought out the detail and colors.
Click on the image to see the original or click this link to see a zoomable version.
Update: I actually captured in 3 batches to give a total of 114 good light frames. Below is the new result and it looks like the extra frames give more detail in the fainter regions.
Again, here is a zoomable version.
