hello first post , first telescope , first of many questions .

well i picked up a celestron 102mm refractor #52270
any way the optics look very clear to me with the 20mm supplied lens i have more on the way off eBay set of 5 ,

so on to the questions ,

i have a t-mount and adaptor for my camera from a c90 F-11 lens ,
in looking at it,, it is different than the telescope adaptor needed for the scope , and mind you i have no idea on what I'm talking about yet ,
i have a Nikon d40x i want to hook up to this scope , i can screw the camera adaptor directly to the focus'er and I see that it gives me the normal 500mm out of this lens , i have a sigma 50-500 with a 2x for it , but i need more lens
my first intended use is for long range wildlife photos .
2nd is the moon and stuff , if the sky would ever clear

so what do i really need to hook this all up to use with the eye pieces

all suggestions appreciated ( keeping budget in mind )
