Hi gang,
I need some remedial education here. I really want a super wide field eyepiece for the 9.25. The docs say:
FOV: standard eyepiece=0.8deg

WTF does standard eyepiece mean? The 23mm that came with it, I assume?

If I order up a 41mm Panoptic (68deg AFOV & 1.1deg TrueFOV), will I be able to see the whole field, or will it be vignetted? Have been reading for three days, but if anything am more confused.

Thanks in advance,
p

Doesn't Televue have 100deg EPs now?!

Rephrase the question in English, please. I doubt I will have an answer then, either.

As I understand it, in an SCT there is a point where the Field of View (FOV) will expand to encompass the baffle tube, thus rendering any wider FOV superfluous because vignetting will occur at the outside of the FOV.

So my question is whether this eyepiece is pushing that limit in a 9.25 and I can't find the answer, or at least one I can understand, anywhere.

In addition, the manual that came with C9.25 gives some of the specs in relation only to the supplied 23mm eyepiece, which kinda sucks. I am not sure if the AFOV specs are for the scope, or for the scope+eyepiece combination.
