Baader Hyperion Zoom

[Charon]

Hi,

Can anyone tell me what fov you get with the Baader Hyperion Zoom.

Thanks.

I believe the field of view ranges from 50º to 68º with eye relief between 12-15mm.

When at 8mm it is the same fov as the regular Hyperions and at 24mm it's roughly the same as a Super Plossls.

This is the description on a popular supplier website:

"This Baader Hyperion 8-24mm Zoom eyepiece has a continuously variable focal length with click-stops at 8, 12, 16, 20, and 24mm and remains parfocal across the zoom range. Field of view varies from 50 degrees at 24mm to a generous 68 degrees at 8mm. As with all zoom eyepieces, eye relief varies with magnification, from 12mm to a comfortable 15mm"

Pibbles is bang on the money

Thank you both very much.
