Baader Hyperion eyepeices

[erg121]

I own a range of Baader Hyperion eyepieces which are both 1.25' & 2' compatible now here's the daft question.

If I use the eyepiece's as 2' do I leave the 1.25' fittings on or do they have to be removed for it to be a true 2' eyepiece?

If it does have to be removed does that change what the eyepiece is for example a 13mm 1.25' eyepiece with the 1.25' fitting removed does that change to say a 10mm?

Thanks in advance

Don't know about Baader but I have some 2" TV eyepieces with 1.25 nose pieces that must not be removed.

It depends. The regular Hyperions don't need anything removed. The longer focal length Hyperion Aspherical EPs (31 mm and 36 mm) have a removable 1.25" nose piece which allows use in 1.25" focusers, at the expense of a lot of vignetting. In 2" focusers, these should be removed.

Not exactly the answer to your question. But this may help in using Hyperions.....
