The innovation I would like to see is more along this line of thinking - what we need is a CCD eyepiece, not monochrome NV devices.
Look how small "smartphone" computers have become, with batteries, cameras, and monitors built-in. Look at virtual-reality goggles in gaming. Let's take advantage of miniaturization of technology.
How about an ocular the size and weight of a 31mm Nagler that has a CCD chip and LCD monitor built-in. You put the eyepiece into the focuser, look into it, and see a real-time, color image of the target. You plug it into your USB charger to charge the battery up before each session.
When I do outreach events I already have people holding their Iphones up to my eyepiece and taking pictures of Jupiter. The next step seems obvious!
I believe that is much more the future. With night photography capabilities improving on smartphones, its in the near future they will be capable of showing more than the visual potential of any telescope. New phone contract due soon, I am looking into that as a major feature to sell me a model....
What is most appealing to me is that if eye relief is too short in an eyepiece wearing glasses, the whole FOV can be seen (& in more colour) afocally with an OLED display. Brightness, contrast, colour, touch screen zooming-in all benefits, and loads of other benefits.
Using a DSLR or mirrorless camera afocally, or not, inline with the OTA, flip screen up instead of a diagonal, gives RACI views & their display & photography settings offer more options than a cel phone currently.
Afocal needs large exit pupils, so longer focal length eyepieces, and longer eye relief I imagine. TV 35 Panoptic & 55 Plossl are fine, but not the 41 Panoptic with its current eye end design, an adaptor or re-design needs making. Do any NV users employ the 41 Pan?
