The first item in the Messier collection is a supernova remnant in Taurus. This image was processed in Affinity Photo (v1) from an observation bundle comprising (I think) 9 one shot observations for a total of 24 300s subs in each of Ha/OIII/SII. I was happy with the colour balance (which I have been struggling with on other targets) and detail which came out without too much of a struggle.
