Skywatcher 10mm MA

[Naemeth]

Does anyone know the eye relief of the Skywatcher 10mm MA?

I was observing last night with it, and I can estimate that I saw about 90% of the FOV with glasses on at a comfortable distance, and all of the view when I pushed into the eyepiece, so what is the eye relief?

[NGC 1502]

It's hard to tell the eyerelief from what you are saying, depends on how thick the lenses are on your glasses, how deep your eyes are within the sockets etc, etc.

A fair estimate of the eyerelief can be judged by looking into the eyepiece without glasses, get your eye as far from the eyelens as you can while you can see the field stop, and ask someone else to guess or measure the distance between your eye and the eyelens.

I think the lenses are about 3mm thick, and I think when my glasses are pressed in there is about 1cm (10mm) between my eye and the front of the lens. So, I would guess the eye relief is about 10mm.. about right?

Funnily enough I posted the same question a week or so ago. The best answer back was c. 12mm. I'm sure the thread can be found by a search if more detail wanted I'll try.
