Pentax telescope?

I'm sure there's a way to adapt this to a DSLR, right?

Yes, you can use your DSLR with the appropriate adapters and/or eyepiece tube.

You might need guidance from an Astronomy forum, unless we have any astonomers in the house?

You would need one of these, plus a T ring for your DSLR.
