Looks really nice Scott. In the early days I used to use the dark patch with three stars to see if I was in focus (see pic below). Is there any facility for image enhancement in Iris such as Richardson Lucy? The picture below was run through IP RL enhancement and even though its a jpg improved markedly. this is also a good way to show up any noise that is present..
Every time the Moon starts interfering I think I should get a H Alpha filter.
Is the filter(s) in square to the optic axis or is the Canon T-mount I araldited to the retaining ring not quite square as there seems to be a slight what looks like astigmatism but is not as it is in one direction over the entire field. This is symtomatic of a slight misalignment some where. Easy enough to test just take two pictures with the camera rotated at 0 and 180 degrees. Like most things it is only just apparent if you zoom right in. In the industry it is called pixel peeping I believe and I am guilty of it.
Again very nice picture. I am still amazed you still manage such quality while guiding manually.
