Hi Henry! I was out at the same time observing Jupiter. Seeing was reasonably good. I was able to use the el cheapo GSO 6mm eyepiece to get up close. Also took a tour around Sagittarius and Scorpio (including Bug Nebula).
I have tried afocal a couple of times but only with the moon. Results are no more than reasonable. Haven't been game to try Joops!!. Iceman has a good article on astrophotography with a DOB.
