I am interested to start digiscoping. I now use a Nikon D90 DSLR. I plan to buy and attach the DSLR to a Celestron C90 Mak (new 2010 model) spotting scope. What are advantages and disadvantages of such a setup?
Using scope's lens, the I know I will have to focus manually (or use aperture-priority settings, if possible (?)). Question: what max aperture will be available to me, i.e., in 35mm camera terms?
I read through the C90's manual and it says I have to remove eyepiece, use available scope's T-adapter thread and use T-adapter to attach the D90. Question: what's the focal length of the spotter scope in 35mm camera terms? I read from some threads in this forum that you can directly attach a DSLR without removing eyepiece. Is this also possible with this setup? How do I go about it? What equipment will I need to buy?
I already have a lot of questions. I appreciate answers. Your responses will be of great help as I will use the proposed setup on my work on biodiversity conservation, including birds.
Best regards to all.
