Nick, what scope sre you intending to use the EP in?
Hyperions are made for use in SCTs & Maks. They do very poorly in Newt's, except for the 5mm.
Pentax are also problematic in different scopes - not all focal lengths do well in all scopes. Some do better in Newt's, others in SCTs.
I don't give blanket "thumbs up" just because of a brand. It's not that easy. Wavy, you know better than that...
Best thing to do, read as many reviews on the eyepieces you are interested in, being critical of the scope the EP is being used in so it is the same as yours. I for one DO NOT like my Pentax 10mm XW. Yes it is fine in my Newts, but it is crap in my C8. I've also owned 5 different Hyperions, thinking that they are good in Newts. What I didn't read carefully enough was all the positive reviews were from SCTs. The only one that is good in Newts like I said earlier is the 5mm, & it is also excellent in my C8, & is the only Hyperion that remains in my kit.
So take your pick - blanket thumbs up, or a bit more reading...
