Description

The famous two galaxies in Leo.
Original picture from 2021. New processing with BlurXterminator and NoiseXterminator. Otherwise based on my actual knowledge.

Version B is a comparison between the old and the new picture. Main difference in processing is the use of BlurXterminator and NoiseXterminator. Processing is much easier on one hand, but the handling of the two programs has to be done with care. Takes some trials to get a proper picture.

The former picture can be found there - some progress is visible!
