Very nice image, not one I have seen done before, guess you need that longer F/L to stand any chance of seeing things like this.

I imaged this before Alan with a shorter FL as part of Markarian’s chain they looked interesting so I had a go with my 11” scope FL of 1764 mm with focal reducer in line I had to crop this image to use some Luminance from last year as the cameras were not well orientated I liked my image better from this year but it Was noisier with only having 15 x300 of Luminance.
