Photograph thru binocular?

Has anyone been successful with this? I tried (the moon) but could not achieve focus with my 7 x 50's

Am I the only one to even try this?

Never tried binoculars, but I did try holding it up to the viewfinder of my telescope once with ok results.

I have tried to take photos with binoculars, but found it really difficult. I would need four hands, besides it is hard enough to hold the binoculars steady enough for long without having a camera to hold as well.

Yes, decades ago. It's hard to hold the two steady. Best to mount them firmly on a board. As to focusing, first set your camera at "infinity", then use the binocular focus knob for fine adjustment. You will get some vignetting in your field of view, less if you have a fairly long lens on the camera.

Magnification. With a pair of 7x50s you will get 7X the focal length of your camera lens, eg: 7x 100mm = 700mm. Your effective aperture will be this figure divided by the aperture of your binocular lens, viz: 700/50, or f/14.

The whole method is referred to as "afocal". Your results will depend on steadiness of the rig and how good the resulting optics are. It can be done. Post an image if you can.

I had the binoculars mounted on my tripod, and was able to position the camera to the eye pupil (hand held). The bin was focused, and the camera I tried at infinity, and a little shy of infinity, but every image was OOF.

I don't have a DSLR with a long telephoto so I tried to improvise, I have successfully taken shots thru a 1.25" telescope eye piece, just thought I'd give the bin a try.

It looks like a combination of unfocused image and a bit of motion blur. More of the latter, I'd say. You should be looking into the camera viewfinder/live view as you focus the binoculars. The exposure's OK.

Good point, I focused the binocular on the moon, assuming then that the camera would see a focused image, this image was taken at 1/160 sec.
