I finally managed to get all the data needed to process this image in spite of the incessant poor weather
; it's probably my deepest galaxy image to date and there are quite a few background galaxies in the field.
Note in particular what appears to be a background ring galaxy seen through the outer spiral arms at about 5 o'clock, and also another one at the same angle but 80% further out from the centre of the frame.
Lum-13x12m, R-9x12m, G-9x12m, B-9x12m
