Binocular telescope
Very similar to your ordinary hand held binoculars.
Usually built on a large scale a binocular telescope are sized around 22inches.
Why would anyone want this? Wouldn’t a bino viewer on a telescope do the same thing?Dr Henry Paul experimented with them in the early 1940’s. Dr Robert Sudding maxed the aperture in the 1980’s with twenty inch class binoculars. I will start off with the problems. It is a royal pain to adjust these binoculars. Being so large you always want to find the object your looking for first with something much smaller. Just like a telescopes finder scope. Adjusting the optics (collimation) is very difficult because you have to match one to each eye.
Although difficult to set up they are extremely enjoyable to look through. Of course the field of view is very large. For me that is the selling point. Its like watching a movie at the theater or renting a video and watching it on your 19inch tv.
