IR vision will obviously not work, and good night vision technology which amplifies natural light tend to be very expensive.

From what I recall from my military service such equipment is remarkably good at allowing you superb night vision in the "darkest" place (some light needed obviously), but the characteristics of the view through these completely and utterly unsuitable for viewing the night sky.

Maybe technology has moved forward since then and there now is such a thing. If so it would be interesting to know how they perform.

That's odd; we had a thread on that very recently: here.

.....these items seem to perform well enough....these kind of images would be fine...just finding out where to get them and what they are really...something i can add on to my telescope or maybe preferably binoculars...but the photo thing is way to expensive...an image intensifier is about 60.00 in places...

Missed that thread.

My experience is similar to some posts in that thread. Spectacular night vision - but personally I did not find them enjoyable to view the night sky with due to the overall "corruption" of colour.

I fail to see how active IR will improve the viewing of stars. Surely, any star gazing improvement must be due to the binos being designed for optimal performance during dark conditions? Or have I missed something?

The most 'economical' way to do this while using TWO eyes is to get a PVS-7 unit with a Gen 3 image intensifier and a c-mount adapter. You can vary the magnification by connecting different focal length c-mount lenses (TV lenses). For example, a 25mm FL lens yields 1X mag. A 50mm FL lens gives 2X, 75mm lens gives 3X, etc.
The PVS-7 requires only a single image tube (MX10130 type) AND you get to use BOTH of your eyes which makes for very pleasing views.
OR, you can get a c-mount to 1.25 inch telescope adaptor and connect the PVS-7 directly to your telescope. This combination works very well.

Hi,
How are you connecting the c-mount adapter to the PVS-7 (as shown in the picture)? Does it replace the entire objective lens assembly? Where do you get the adapter shown? Thanks.
