How would you compare it to the 35Pan in an f10 SCT?

Good review, David.
How would you compare it to the 35Pan in an f10 SCT?
In the SCT, it is a tough choice, but the 35 Pan has slightly better astigmatism correction and more eye relief. Cost wise, the 36 Hyperion has the advantage. Clear skies to you.

Occasionally, I need a little external validation. Nice to know that you don't think I made an awful mistake.
If you need some external validation yourself, David, let me know. I've always appreciated the generosity of some of the knowledgeable, thoughtful members of our community who go to the trouble of sharing their experience and judgment. You certainly fit that bill to a "T."

Although a little different focal length, did you ever look thru a 40 Paragon or 40 Titan-II ED? Curious overall if you would put the percentage of clean FOV of the Hyperion in the same class, a little worse, a little better in the faster scopes?

Very nice review! Thank you.
I find the Hyperion 36 works just fine in an f/10 C8. It provides very good views without the high price of Naglers or a Panoptic 35.

I 100% agree with your review, you validated pretty much everything I said. I will say that the 31MM is a better eyepiece in faster scopes, I would like to read a review of the 31MM.

I have used the 40mm Paragon in my 9.25 inch f/10 SCT, and it performed well, but not a lot better than my old University Optics 40mm Mk-70 Konig. It is tough to say whether the 40 Paragon would be better than the 36 Hyperion since they differ enough in focal length. Both are pretty good eyepieces. Clear skies to you.

With regards to the 1.25" adapter, I know it seems redundant to those who have 2" focusers, but for a long time that's all I had in my 10" f5.6. In THAT scope, I enjoyed comparing the view with my 32mm TV Plossl, and found that with the adapter installed, the AFOV was appx. 60 degrees, and edge quality was significantly better compared to the Plossl.

Do you have any idea how either the 31 mm or the 36 mm would fare on a C8 f/10 with an f/6.3 focal reducer?
Thanks.
