Thanks, gbeal, and ving for your response.
I think i might have guided you up the wrong path, (so to speak)
I do have adaptors and that sort of stuff, and have been imaging with film and my Pentax Istd for some time now.
Basically what i was asking was, which model Canon Camera would be the one to get.
I was looking at three models.
No 1 Canon Rebel XT (350D) spectrum enhanced camera with built-in astronomical UV/IR blocking filter (type1a) and accessori US1300.00
No 2 Canon 30DH spectrum enhanced camera with built-in astronomical UV/IR blocking filter (type1a) and accessories US1850.00
No 3 Canon 5DH spectrum enhanced camera with built-in astronomical UV/IR blocking filter (type1) and accessories US3,500.00
Out of these three i presume that 5DH is the best but also the most pricy, would any of the other two do the same jod, do you think
any other bits and pieces can come in time, i just want the camera for now.
thanks Leon
