Hi all
for those of you who have followed the long thread in the Equipment forum will know that I have been in pursuit of a widefield solution for sometime.
With your help, I managed to get satisfactory results out of the Canon 50mm f1.2 L lens when paired with an SBIG ST8300.
So, having worked through that, I took my first HaRGB image tonight - nice and quick i.e 60:10:10:10 minutes centred on Eta Carinae.

The RGB 60 second subs were unguided and each set of integrations was manually focussed (havent sorted that out yet).
Its a bit noisy I think, but I am fairly happy I have the widefield solution I was looking for with this now, so thanks to you all who contributed to that.
cheers
Martin
