Now I'm geting a little confused....

I'm not sure how exit pupil affects what is actually seen through the eyepiece. On my f6 dob, the following would apply.....

1. 24mm Panoptic - exit pupil 4mm
2. 17mm Nagler T4 - exit pupil 2.8mm
3. 10mm Pentax - exit pupil 1.7mm

So, if the TFOV between the 24mm and the 17mm are very similar, what is the effect of the different exit pupil sizes? Does a smaller exit pupil mean less detail, like looking at a smaller vs larger computer monitor?
