The Tele Vue 24mm Panoptic is nice but only 1.25". If you want to maximise your widefield vistas you need to go 2" which your 'scope will handle. For maximum true field at 68 deg. apparent field the 41mm Panoptic performs very well under dark skies giving you 4.3 deg. The 7mm exit pupil is not an issue with a refractor and will give bright images but off course a smaller exit pupil will give a darker sky background in the city.

For slightly less true field but wider apparent field of 82 deg. the 31mm Nagler would be my preference for this telescope however it is larger and heavier than the 22mm Nagler. You could also choose from 35mm Panoptic or 27mm Panoptic both of which are 2" than their respective Nagler counterparts but you will be giving up true field.
