Glad to hear it and good on you! The numbers on paper can tell you one thing but in reality the concerns about large exit pupils are overstated. You're using your 'scope as a low power finder/sweeper and it really doesn't matter if you're effectively not seeing the full area of your primary because your exit pupil is larger than your entrance pupil. Enjoy the views!

I use a 41mm Panoptic on a 10.1" f6.4 and 6" f5.5 Newtonian, (sometimes with a Paracorr but usually not) and my sky background is reasonably dark and I really don't care if I 'me not getting the full mirror as it is the wide field I care for more.
