Yes i could only imagin something like a meter wide mirror. Perth obs in biction has some good gear, though im especially fond of the old 1900's one they have there. im not sure what size the mirror is but it isn't small and i can remember omega cent as bright as a normal star and clearly seperated stars.
I guess the reason why i am running with photography for now is that i cant see those faint fuzzies without having to have a mirror that size. Dont get me wrong im all for looking at them in real time, theres nothing that beats your own photographic rendering of a image in your head!
One day i will more than likely get a massive dob, but i just don't have the carrying capacity with a little coupe and its not that easy to lug a big mirror around by yourself.
So last night when the minister of war and finance approved the purchase of the eq6 i was stoked because all i need now is a guide scope and camera to run in it and a cannon 350d,400d,450d and im away! Plus she can look in and see what im doing.
