Oops, we've kinda derailed this thread, sorry Barry
Definitely worth pursuing.
The subs were 10mins with a little 70mm achro at f6.
The Carina neb is ofcourse very bright, but I reckon with the 102 f5 you have you'll be laughing.
I recently did some test shots with a 6" newt at f2.8 (~f3 light grasp when accounting for central obstruction) and Carina's core would be overexposed at anything over 5 min subs!
Same result with M8, overexposed core when over 5 mins.
The newt still needs some fine tuning before I can get serious with it tho.
