Wow sorry Gav, I missed this thread.
Welcome to IIS.
Awesome Canon gear you have there.
I agree with Jerry, the mount is what will play a huge roll in the quality of your work.
There's a lot of people using the
Losmandy G11 mount and it's got great payload capabilities.
I'd be leaning towards Celestron for a SCT, generally the quality is better from what I hear although the Meade LX200R is yielding some excellent results for one of our members,
Tony (Striker).
You'll also be able to do some fantastic widefields using your Canon lenses.
These fast lenses are perfect for astro work.
Do you have any other longer FL lenses?
If you're in the Sydney area, we meet up at Kulnura every new moon.
Perhaps you could come up if it's not too far for you.
BTW if you are looking at a Meade Fork mount setup, you'll also need to get a wedge for an equatorial set-up since the fork mount is alt-az and not suitable for long exposures.
