The binocular you posted has no chance to work there.
In space all the plastic would join together because of a phenomena named "vacuum cementing", a kind of "cold welding" which happens in hard vacuum. https://en.wikipedia.org/wiki/Vacuum_cementing
Until your binocular is not made of a very special material , it would be at least impossible to operate like we do on our planet. Maybe you should consider magnetic lenses, which have a lesser need of little parts moving while touching each others.
Of course, your superhuman should be able to see electrons instead of photons, but since heavy particles and high energy particles are quite common in space, it maybe not that hard for your superhuman. ;)
Another alternative you have is to use a mirror-based telescope, which doesn't needs so many moving parts as the model you posted.
