There seems to be a lot of people trying to go down this path with DSLR's and imaging the planets.

He is a little slow to respond, but I know he has them. You will need to use an adapter too and he has them too. Total cost something like 250 dollars. You just need a laptop to complete the basics. A good quality barlow and you can be like the rest of us waiting for that night of perfect seeing.
