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