Billy why do you need a 2" diagonal for astrophotgraphy...???????

Put the DSLR straight in the back of the ED80...if you cant get focus buy a 2" extension for about $40...thats what I use.

I'm sick of kneeling on the ground to view the back of the camera. With a refractor it'll be worse and I'll be near lying on the ground. I want the convenience of the diagonal to pop in and pop out eypieces, video camera and dslr when experimenting. When I go for quality shots I'll just use a straight-through extender.

Does anyone know of a good brand/type of diagonal for this purpose ?

I bought a right angled view finder for the camera, but if you insist get a Williams Optics 2" diagonal or try the bintel one.

If you have got a laptop, whynot get DSLRFocus, never get on my knees with my Tak and it's a lot longer than an ED80. Would you get enough "in focus" with a 2" diagonal?
