2" Camera adapter for my Nikon D40

[TenBears]

Hello.  I have a Zhummel Z12 Dobsonian - with a 2" focuser. 

I want to be able to stick my Nikon D40 in it and snap a few pictures, mostly of the moon, and experiment with maybe Jupiter.... (I know I can't do long exposure DSO images.).

Would these two items do the trick for me - and would be all I need?

HOTECH 2 Inch SCA Telescope T-Adapter

 Zhumell T-Ring for Nikon Cameras

I don't see the point in getting a 1.25" t-adapter, and then have to use another adapter on that....

Thanks for your advice!

I'm going to guess, yes?  lol
