A classic interacting galaxy pair, which you've captured nicely. A little focusing issue but a great job nonetheless. You're a brave man to publish your deep sky images this size!

Hi Peter,

I usually re-size my images to about 500-600 pixels x 400-500 pixels at 250 dpi resolution. This gets the image to about 150-200kiB, which sees to work about right on the web site.
All best,
David
