Centaurus A - again!
This one is a 3.4 hour RGB grab taken Monday night. The original image was cropped from 52' square to 22' x 20'. Processed in Pixinsight, finished in PS.
At the next opportunity, I will shoot a few hours of L, which I hope will drag out a bit more detail.
Monday night was fairly clean: seeing 1.8" - 2"; best SQM ~21.2. Almost no surface wind.
