Jeez I wish I had a better mount!!!
Just looked at leon's and tornado33's RHO region pics before posting this - very smooth!
Just the facts ma'am...
Canon 40D (M) ........M for modded!
Canon EF 70-200mm f4L Lens @ f5.6/70mm FL
iso 1600
20x10mins exposures
Skywatcher Synscan EQ5 Mount
Autoguided with PHD
Stacked in IP, Processed in PS!
Thought I would be a smarty pants and tried to take around 40 darks in the cold dark shed after 3hrs worth of imaging lights. But, should've done darks throughout the whole imaging process or done ICNR!
This worked out badly - lots of little black pox-marks all over the stacked image.
Decided to just stack the 20 subs alone.
Cheers
Doug
