How Does the Hyperion 10mm Rate?

[andrew63]

Thinking of getting a hyperion 10mm.

Was wondering how owners rate it? It would be for use in a 4" F7. Not owned any before but from what I can gather people either love or hate them!

thanks, andrew

Love mine. They worked fine in my ETX80.

I think the Hyperions work well at F/7. I've tried most of them. I don't know if anybody actually hates them but, like many low to mid price wide angle eyepieces, they do show astigmatism in the outer parts of the field of view in faster focal ratio scopes. I found them very comfortable to use.

Most of my kit is Hyperion eyepieces and the 10 mm is my workhorse both with my 8" f/5 newt and my 102 mm f/11 achromat. When the seeing doesn't permit use of the Hyp 5 mm I go back to the 10 mm and add one, or the other tuning ring. I've had the 10 mm now for about a year, during which I've observed with it at least 50 hours. I'm very pleased with it.
