The first target of my renewed interest in using a DSLR. The 3/4 moon was out with clear skies (rare in Michigan during the winter), So I wanted to see how the acquisition workflow would work with a DSLR, SGP, ONAG, Focuslock. Quick summary: it works really well and now need to get the rig out to a dark site around new moon. Also I was working on a new DSLR PixInsight processing workflow and the I am pretty happy with the results considering the short amount of total integration.
