The 27mm Pan might be the next best option if the 35mm is no good.

Mike the 27 panoptic is a winner in a 10" f5 dob. I used to own one until I got the 31nag and 24 pan to replace it. I miss the 27 !
The exit pupil on the 35mm will be 7mm, which will result in a milky white sky background in anything than very dark skies. The 5.4mm exit pupil gives a darker sky background which is a lot more pleasant.
