I really enjoy using 2 pvs-14 as a binocular as per this thread

https://www.cloudyni...ion-binoculars/

You can definitely see more nebulosity with two eyes.

 

However, this was only at 1x, I wanted to see if it worked well

if more magnification was used with a binocular.

 

I was also keen to be able to use my 55mm plossl afocally to increase the effective speed but didn’t find anything that I thought would work well.
Then a few weeks ago I saw that Williams Optics has launched a 103mm binoscope with capacity for 2 inch eyepieces.

I immediately put in an order and it arrived today.

And we had clear skies so I was able to get out immediately and test it.

In summary, I’m very impressed. Two eyes at around 12 x is great. I was observing in my london back garden so not ideal but the views of the horsehead rivalled those of my 16 inch dob in the same garden with a clear black outline. The rosette was the best I’ve seen in London, really well defined and detailed. The binoscope has plenty of in focus so I was even able to use my 0.75x reducer with the plossl to increase the effective speed of the system to around 2.5.

 

It clouded over pretty soon but I can’t wait to try it again. A big thumbs up. I definitely like two eyed night vision observing.

I enjoy my Lunt 100mm APO ED binoculars but I will restrict my night vision to mono. I don't see dropping another $4K for a 2nd unit. 

 

I am sure you will enjoy your views.

Binocular summation is powerful stuff. It increases the brightness by about .3x and reduces the perceived SN but perhaps a similar amount.

 

Congrats on your image intensified binocular scope!  Very fun for you!

Now THAT'S Exotic! ...I know you will enjoy them.  waytogo.gif  Congratulations Gavster.  I wonder what you'll see from the Isle of Wight with those beauties?

Ray, thanks. I was thinking exactly the same when I was looking through them last night - can’t wait to get them to the Isle of Wight for some dark sky action. I don’t often observe with both eyes - it’s an interesting experience, there’s something ‘extra’ about it that I can’t describe - a bit of depth perception (which is of course nonsense on stellar objects), and more comfortable due to not squinting. I think it helps that my eyes are very similar. Certainly finer detail was apparent to me last night.
