Nice work Steven, there is certainly a galaxy in that image so your budget Where's Wally approach to finding it and framing it looks to have been successful
.
Did you use accurate flats on this image? I ask only because the apparent glow of the galaxy also looks decidedly like vignetting so it would be nice to confirm that you are indeed picking up the actual glow from the galaxy, all images I could find, including very deep amplified UK Schmidt shots, show no uniform circular glow like that in your image...?
Very interesting image mate, thanks for shooting something a bit different
Mike
