Tele Vue 35mm PanopticThe 35mm has a large true field with plenty of eye relief for eyeglass wearers. When combined with a Paracorr to correct the coma of an f 4. 5 Newtonian, performance is spectacular across the 68 degree field. Imagine, sharp star clusters at the extreme edge of the field along with a 6. 8mm exit pupil!
