So, Josh Lake, who I met over on Reddit's Astronomy Sub-Reddit kindly offered to have a go at re-processing my M31 data from the 15th Jan using PixInsight. I have to say that I have been pretty blow away with the results.

The additional detail in the dust lanes, better colour and higher contrast just brings the image alive. I almost feel unworthy of posting this image as really Josh needs most of the credit.

Anyway, here it is...

PixInsight is certainly something that I am going to have a very good look at. The good news is that you can get a free 45 day trial period over on their website. I would love to hear from any other users.
