Description

M51 aka Whirlpool Galaxy. This was imaged late last year, but I had a bad light leak from a light in the house via the gap around the primary mirror (took a while to work that one out!!). I'd previously been unable to get anything good out of them, but recently bought Pixinsight which is really quite amazing at recovering images using Background Extraction and Neutralisation.
