M31 Reprocess

Hi Everyone, this is another one that was taken on the 27 & 28 Oct, while chasing clouds around my imaging targets. You can tell it's starting to get warm up, up this way, the colour noise in the background is unavoidable at this time of year. Won't be long and the wet will be here and then I'll do a cooling mod. Next year should be a ripper.

Image details:
26x300sec @ ISO1600 with the gear in my signature.

Edit: Ok folks, after Al's reprocess and guidance with the tutorials he posted, I had another go at processing this one. I have attached it to this post. Although I do have photoshop, these days I tend to process all my images totally with pixinsight. PI doesn't have rope selection tools or the like because when you use these tools, you are manipulating the data it an unnatural way, meaning doing something to a certain structure rather than to all pixels at a particular brightness etc. (I am not criticizing anyone for using these tools, as to highlight some structures you need them). I still prefer Al's repro because he managed to bring the pinks out in the nebula's by using such tools. However I am trying my hand at staying true to the data bla bla bla, so decided not to use them. The attached reprocess is the closest I can come to Al's with my current knowledge using PI. I am sure that with more practice I will be able to get there, but for now this is it. I may have a go using PS later down the track.

Thanks for looking.
