But Jase, OK .90 arcsecs/pixel doesnt make full use of the available res, but given the huge leap to an astrocam, its not a big disadvantage, surley. Better that than too far the otherway;-).

Im not sure about this, but wont a barlow give massive vignetting with a DSLR?.

Mike, the ED80 DSLR is a nifty combo, seems to me you could get some increadible images 1st before you move to a longer FL. A longer FL especially over 2000mm is fraught with pain to get the image quality I suspect you will eventually hope for, youd really need to spend big for a good mount 1st methinks.
