Hi Guys,
At last I have some kinda of result to post - cool and clear weather here in perth finally!
M104 using a canon 50D, 6 x 10min shots at ISO 800, Processed in DSS and tweaked in Photoshop CS4.
This image has had 5-10% cropped off due to my bad framing after doing a focus check at the 30 min mark

Need to get some kind of field flattener into the mix with the DSLR though.
Cheers,
Grahame.
