Low Power Eyepiece to match Hyperions

[AndyWB]

Right, I've been using my Equinox 80 as my grab and go lately, but I'm getting really annoyed with the difference between between the 10 and 5mm Hyperions I'm using, and the 28mm Maxvision. They're massively different focus - like other ends of the focusser travel. And I keep forgetting to transfer the 28mm Maxvision to the right case...

Anyway, does anyone have any thoughts of a reasonably parfocal 2" eyepiece for low power - preferably somewhere in the 30-32mm range? (And not absurdly expensive.)

No Idea although you could try using parfocal rings!

[AndyWB]

I've not come across those before - interesting idea - though kinda pricey for what they are!

365astro do a decent deal on them, in the barrel extenders where needed that ramp it up. All for the greater good though

Hi Andy, thinking of ep's, the Baader Hyperion Aspheric would seem the obvious choice given your current configuration, though I don't know how parfocal it would be with its siblings, perhaps this is something you could check with FLO.  Failing that I favour the SW Panaview 32mm, a stunning ep for its relatively low cost, a no-nonsense alternative in my view, but parfocaliality(?!) unknown. It would not perform so well in your 250px as it is best at f/6 or over though on-axis it would be good.

That's a good idea - I didn't think of asking them.

And I'm not too bothered about compatibility with the 10" - it really is more for the Equinox 80, so a bit slower.
