My problem is the interpupillary distance and eye placement needs to be exact or I get blackout. I am thinking of 24mm Hyperions, but would like imput. Do the Hyperions pinch your nose due to the diameter of the eyepiece? I realize this will vary from person to person, but would like some feed back. I also would like feed back on vignetting, as the Denk. has 26mm clear aperture and the Hyperion has 29mm.

Also, for some reason, the smaller lens of the 24 makes it easier to view (eye placement) than my 17mm Hyperions. I really haven't seen any noticeable vignetting.

Broke my nose in highschool so I've a ridge that gets in the way PLUS a narrow IPD and the 32MM's were tight. Removing the rubber eye cups does help. Also, there will be a bit of light loss at the edge of the field. However, they do give you just about the max TFOV possible with the 1.25" format eyepiece and they are sharp. The 24mm Hyperions should be ok. If I may suggest, the good old RKE 28MM or the Edmund 28MM Plossl version are excellent low power choices.
