Great! It's interesting to see the integration before deconvolution. I have a similar integration with a 200/750mm and an IMX571, and I don't have nearly as much detail/sharpness.

I didn't use any paid plugins, by the way. Deconvolution was done using MLT in PixInsight, so without deconvolution, the overall volume would remain the same—just a slight drop in sharpness at the edges, that's all. I didn't process the stars at all, just a histogram stretch after separation.
