Cheers 5ash - I said I'd have a go at it. Could have done a little better with the framing in the end but I'm still very happy with it. I got the other little galaxy in there too (NGC 4976).
Regarding the GSO coma corrector - I think it's really good at F/5. Unfortunately the t-adapter is set up for Canon (as can be expected) and since I use a Nikon I still get a little coma in my images. If I'm prepared to crop a little then you don't see much. One day when I win Lotto I'll get a 6D and it'll work perfectly, lol. I presume at the correct spacing it holds up well at F/4 as well. That's what it's marketed as handling.
Cheers,
