What is it?

The challenge involves crosshairs in the optical device pictured in the challenge. The circled area is a feature that enables crosshairs to be used at night. What is the term that refers to crosshairs that are visible in darkness?

Night sight or night vision?

It's not night vision,it was made almost 100 years ago. The monocular is not a specialized night sight,but could be used at night but crosshairs are not visible in darkness unless•••?

Have no idea unless it's LCD?
Can't take time out to do some googling at the moment so must leave it a mystery. Sorry!

I can't stay to monitor the challenge,so I'll give you the answer.The answer I was looking for was illuminated reticle. The circled area in my second photo is the glass illumination port for the reticle. An accessory light was shone in this port,illuminating the crosshairs and making them visible in darkness.
The Admiral correctly answered the first question in the challenge so if he wants to post,he can do stherwise the challenge is open to any IPF member who wishes to post a challenge.

That's interesting and surprising. A light shone at night could reveal your position to the enemy. And yet the monocular had to be used in the open to be effective. Was it a red blackout light that was used?

The illumination device clamped closely on to the reticle illumination port on the monocular,allowing no stray light to escape. The only way to know the light was switched on would be to look through the eyepiece. Looking through the objective lens would reveal no trace of the light so nothing would alert the enemy.

Do you have an image of the light that's used?

Sorry,I don't. I've never even seen a picture of the illuminating device.

Well it sounds very high tech for something conceived of almost a century ago. I've only got half a foot-in at the moment. I'll try to post a new challenge shortly. If anyone else is at the ready, please jump in.

Ok, I can't stand it anymore. I'll just have to find something to present a challenge after the fact.

This is a CD collection of the Outer Limits science fiction (and other weirdness) series.

I recognized the series immediately, though I didn't realize it was a CD collection until the last pic.

It is The Outer Limits. It's a DVD collection. And physical proof that well written television is timeless.
Over to you for the next challenge tp.
