Thanks all for the feedback,
Humayun im not overly stuck on the Nikon dslr's, actually in the back of my mind im still looking at the 450d or higher. Its just with the advancements Nikon seem to be making lately across there range they were worth a look, just doing some research how these newer models have been fairing, especially in the area of AP.
Software seems to be a bit of a problem with a trend toward supporting canon. Another big thing is that the Nikon's still seem to do this post processing altering the RAW files but can't confirm this. And the apparent bad transmission of H-alpha through the IR Filter, something Canon can boast about. Still a few unknown's
Luka you said you read somewhere that D90 has excellent response for H-alpha, so maybe things are changing a bit
. Problem is there wouldn't be to many newer Nikon's being used for AP to report back on. Its like in the old days, Beta was always better but we ended up with VHS ( Im not that old by the way but I do remember it ). Maybe the playing field is leveling out a bit.
Cheers and thanks for the feedback, its much appreciated
Scott
