    Description

    Due to consistently bad weather over the last two months I've re-processed the data from last year. I wanted to see whether the current processing workflow produces a better result. I definitely hope so!

    Color calibration has been done using AutoColor script in PixInsight.

    The revision A has been rotated in order to view the Needle galaxy from the top. It looks as if a small NGC4562 chases the UFO (NGC4565) through the stars :)

    Revision B has been annotated using SIMBAD catalog. It turned out that there are a few quasars in the field.

    Here is the old image:

    Thanks for looking!
