Eyepieces for Helios Quantum 7.4 Binoculars

[mike.brightmore]

Can anyone recommend eyepieces suitable for Quantum 7.4 binoculars. Ideally some that would provide around 40x magnification with 70 degrees AFOV. These binos have 100 mm objective lenses and a focal length of 600 mm. so 15 mm EPs should give this magnification but presumably vignetting could be an issue.

A pair of 16mm Uwan's would be pretty awesome.

What about University Abbe Orthoscopics at 12.5 mm? They are cheap and will give you a better magnification. Have ever seen trough a UO?

Thanks Doc (as if I needed any help to spend, spend, spend). I love the idea of WO UWANS but they might just be too good for the binos optics. Would certainly double up in binoviewers for the main scope though. Hadn't heard of the Abbe University orthos Makron. Who is the UK supplier? Will certainly have a look at them. Had a quick look at Jupiter and the Moon tonight at 40x mag in between the clouds. The EPs didn't match properly - an Antares 15 mm and a borrowed Ascension 15 mm SWA but the views were truly amazing.

Unfortunately they have sales by Internet.

Thanks for that Makron. The University 70 and 80 FOV look very similar in appearance to the Ascension EPs. Baader Hyperions have also been strongly recommended. In the write-ups it states that these are particularly suitable for binocular and bino-viewer observing. You do have to be careful because some EPs are too 'fat' to squeeze together to get the correct inter-pupillary distance.
