Andromeda mosaic

[alan4908]

I decided to have an attempt at generating my first mosaic and picked M31 since it would require only 4 panels to achieve a reasonable framing.  Having learnt how automate the image acquisition, six weeks later I had quite a few images....... I then had to figure out how to assemble the mosaic.  After a little research, I  decided on a combination of RegiStar and PS and ended up with about 13 hours per panel with a LRGB + H blend.  The result is below, which I quite like.  Comments and constructive criticism are welcome.

That is incredible! I love it and the cropped image is brilliant as well.

Superb mosaic image, can't see the joins. An impressive 51 hrs data!

Thanks Peter  - I think I'll go for a non-mosaic image for my next target.  Even with my automated image acquisition set up, acquiring this amount of data under UK weather conditions challenges even my patience levels

Great image....like you, after finishing a lowly 2 panel mosaic, I decided I may NEVER want to do another mosaic (not really), but certainly not for a while.  Yours is brilliant though and adding a few panels to get a deep space setting for this jewel would be awesome.

Thanks for the comment Rodd. It was quite satisfying to finish the 4 panel mosaic after the long wait. So, at the moment, my enthusiasm for adding additional panels is approximately zero - but who knows, maybe this will change in the future....

A wonderful image, was going to show my latest M31 but after yours mine would be shamed.

With your permission, I'd like to use the zoomed in version as my desktop wallpaper this week please?

Phenomenal effort and marvellous image.

Thanks for the kind comments.   I'm hoping that my next target (M33) will be acquired somewhat more rapidly than this attempt
