How do you find stars without a finder scope?

Hello. Want to move up to a RASA for imaging. What would I need to use my Nikon D750 with this scope?
We do not recommend using the Nikon D750 DSLR camera with the RASA 8 as the camera body will obstruct part of the corrector plate. Sincerely, Celestron
