T ring adapter for Pentax K10d

I have a six inch newtonian reflector telescope with the standard 1.25" eyepiece. I need to get a T ring adapter for my Pentax K10d but not sure if the size is the same as the *isd as mentioned in the scopetronics website.

Anyone help me out here? I would then also have to get an adapter to mount onto the eyepiece itself and I assume that would be the standard Stt125.

The Pentax DSLRs all have the Pentax K mount, so your answer is that there is no problem. It is on the list of adapters.

That's really useful info. Thanks!
