Description

The Antenna galaxy
This is actually a mix of some older and unused data, I selected the best subs that were between 0.7" and 1.2" for the luminance.
The rgb data was not that good, more around 1.5" to 1.8"
I used BXT on the luminance and on the rgb seperately, for rgb I only used sharpen stars to get them to match.
What I did was upsample the image to 200 percent before applying BXT, it seems to give me the best results doing it that way.
Sure is the better the initial fwhm is and the better the results are.
The image is a LRGB 120 60 60 60 min.
Hope you like it
Wolfgang
