Markarian's Chain and M87
Always found this area very challenging to process - so, being impatient I thought I would have a go with a partial data set, not the best logic!!
On previous attempts, I have found the background is quite difficult to 'make nice'. So here I used the Lum element of the RGB frames and applied back to a processed lum frame background. Results are quite pleasing - A four pane mosaic will follow of the extended area out to M89 and the two panes below as soon as I can find the time.
