vixen 30mm plossl

[sunshine185]

Has anybody used something around 30mm in a binoviewer? Was looking at the vixen plossls but I don't want to waste my money if they will vignette badly. I've heard of people using televue 32mm plossls with great success so I'm hoping that 30mm plossls will be ok.

The field stop of the 30mm NPL measures 24.6mm, which is somewhat less than the 27mm of both the 24mm Panoptic and 32mm Tele Vue Plossl.

Thanks for the info. IIRC the aperture of the bv is about 23mm so hopefully there will be hardly any vignetting with the vixen plossls. Should give me a nice wide fov in the binos.

I use a pair of NPLs in my bino, though the 25mm version, so can't help on the vignetting.

However,I can vouch for their quality, I have found the NPL's to be excellent eyepieces very sharp with good contrast.

I do know that a memeber over on CN is happily using a pair of NPL30s so I doubt you will be able to detect and vignetting.
