Description

Hi everyone,

I took a really long time finishing this image. I put it aside multiple times because I just was not happy with the results at first. Now with an extended weekend coming up I went at it again and this time I managed to get a satisfactory result. As with all my galaxy images I think that it is worth looking at it in full resolution and pan around finding galaxies.

The seeing was horrendous but deconvolution helped me salvage the image in the end :)

Thanks for looking!
