Description

Note 2. July-2019:

This image sequence is still categorized as "Lacking data", one of 20 pics, which I don't understand?

What is missing?

M31 shown "inversed" as a study in grey tones.

I took this M31 color submission, http://astrob.in/312071/0/

and made a BW version.

Merged these parts "inversed" into the Picture.

M31 center part,

NGC221 part,

All subs from these 3 close-up pictures were taken in the past with my 16" SCT setup.

Picture size shown is 50% of the full sized image and further enhancements done with PS CS6.

Kind regards Niels
