I dont think there will be many amongst us that will ever own an AP 6" in our lifetime??? how much are they again? I think I may have heard the price tag of $50 000 US once??? I could be way off, but i know they are not cheap and readily available (isnt there a 100 year waiting list for there stuff? hehe - your sons and daughters may get it

LOL - i am exagerating of course )
I agree with Chris there - maybe if all those dslr's you mentioned had been modified for the ha like the 20Da they would do the same job?.
Davo, Chris got that awesome shot with a $700 ota ( I think) - I cant imagine anyone could get a better result than Chris's M42 with the same set up as he used.
Tony - youd better start saving

only joking
