Description

This is an attempt at trying out my new L-Enhance filter. I apparently have some dust that my flats were not able to correct.

This was shot from my backyard which is now totally surrounded by street lights, so basically Bortle 8. So I am thankful for the L-Enhance filter. It does a good job.

I was only able to get a little less than an hour because of trees.

New version, playing with color channels.

For this version I used the WeightedBatchPreprocessing script in PI followed by a Drizzle Integration. I also used some of the Color Calibration tools. Then, I ran the image through StarNet and finished with some work in UnsharpMask. The resulting image is less red and more yellow. I wonder if this means that my CFA settings were wrong?

I added one more night's worth of light frames, re-shot all of my flats using a light box, and then re-processed everything in PI using the WBPP script. This version skips StarNet and I think the results are cleaner.

283 x 120 seconds @ iso 6400. WBPP and drizzle integration in PI. I think less processing produces a better image.

Description: Same image source as before, but this time I tried out the Photometric Color Calibration tool which gave very nice results.
