Great Image, with a very natural look!
May I ask the procedure you follow to get such a clean starless landscape? I employ a newtonian telescope that, specially in narrowband, generates several star halos and spikes. As a consequence, when I apply starnet, I get a starless image that is affected by optical "crater-like" remnants, that I currently clean out manually, by selecting with Multilevel Median Transform the relevant layers, and cleaning carefully the noise with Clonestamp.
Many thanks in advance for your advice, and have a nice weekend!

thanks for the nice note! on this one i used starxterminator. the ota is a refractor so no spikes. SXT did leave some small spots around which i should have tried to smooth out. but aside from SXT there was no other star removal technique.

Thanks for your swift answer! I thought you used a refractor, and hoped that you used Pixinsight to get your advice. :-)
Congratulations again for the refined technique and good taste in processing the image!

i do use PI and your technique sounds right to me. SN was trained on refractor images which probably explains your artifacts. SXT seems to do a little better with diffraction spikes.

Hey Rob, see this uses either PI or PS. Assume you bought the PI version? But looks like it may require using layers... when are they going to use layers in PI!

i think the license is universal… doesn’t need layers in PI, it works pretty much the same as StarNet.
