It's nice to have a few sunspots to image these days after the recent lull. Today's images, processed with Autostakkert, include both "non-conv" files and "70% conv" files which were minimally treated with unsharp masking in ImPPG resulting in a softer image preferred by some. I still maintain there is a place for the "conv" approach.
