In case anyone missed it, there is a new NV optical accessory on the horizon from Televue. It easily modifies a 55mm TV plossl into a 67mm exclusively for NV use. This both increases the field of view and reduces the image size projected on a NV objective. If my calcs are correct it is optimal for something around f/3.3 which results in about a 20mm exit pupil for the NV objective. Of course it'll work for other f/ratios too.
Mike Lockwood has the info from Televue released to date. Go to the very end of his article (However if your into NV I recommend reading the whole article):
I understand a prototype was tested at WSP. Maybe we'll get some feedback.
Thank you uncle Al (and Mike)!
