Hey i was looking to take some shots through my telescope with my Nikon D50. and i was a lil confused of exactly what i need. i need a t-ring, i know that i found them on ebay for like $15. but do i also need another piece? one sight said an adapter or somthing, then another site said adapters were just for P&S cameras.. another said something else.. and im confused, the T-ring dosent look like it will allow me to attatch it to the scope.. so im pretty sure i need the other piece but im not 100% on what the piece i need is called. so lil help? i wanted to get some nice moon pics. my telescope.
