While our primary use for NV might be astronomy, I am enjoying NV a great deal for other use as well. I am always geeking around with NV and I hardly ever go anywhere at night without my Micro.
Here are a couple of fun things that you might consider for your NV to make it more useful. Now these are not all that essential, but hey, they are cheap, and for general NV use, especially for night hikes, both can be quite handy to have, and since they are inexpensive, why not!
The first is an IR Beam Focuser. This little device press fits over the IR stub on the front of the PVS-7, the Mod 3 power supply (I do not know if this works on the PVS-14). Again, it just press fits on (kind of screw it on, but it is not threaded.)
What this does is adjusts the pattern of the light emitted by the built in IR illuminator. The illuminator by default is set as more of a mid-flood. With the above device, by twisting it, you go to a narrower but intense beam that can illuminate maybe a meter wide circle at 25 meters. The idea is that if the illumination level is very low, this can give you a little better definition at the center of the field by providing a little extra light. Turn it the other was for more of a flood. The Mod 3 built in illuminator is very bright and it is exceptional for things like map reading, but you can get of a bit extra throw using the focuser:
The next one will work for the Milspec objectives PVS-7, PVS-14, and ENVIS. This is a compass. It simply clips over the splines on the objective. On the base of the compass, there is a little button, and when you press and hold the button, you see the magnetic heading displayed in the eyepiece FOV. This is what it looks like. Forgive out of focus center of field. I must have moved from where I had the objective focused but while the scene is not all in focus, you can see that the compass card is in focus.
This one has Make Offer, and I bet you can get it for $25 shipped.
Next are IR Glow Sticks. These are like the regular green glow sticks in operation, but rather than glow in green or yellow, they glow in IR. Now where this is particularly useful is for tagging your dog or your friends if you are out and about at night. Tie one on Rover's collar and you can see him from 150 yards away. Also, if you want others to see you and you think they will be using NV (perhaps in a search) cracking a stick might be a good thing to do. Once again, these are inexpensive, and while you may not really think you need them, they are inexpensive.
IR Torch. Some of these are not much more than red laser, and this means people can see it without NV if they look at the source. The big benefit of using a torch rather than a simply flash light (and make no mistake, there is nothing like a good flashlight) is that no one can see it, and better than that, it does not affect your dark adapted vision. If you are helmet mounted with a monocular and want to reach out into a very dark night, the torch will let you do so without suffering loss of scotopic vision in you other eye.
Helmet and helmet mount. Works with pretty much anything. A helmet lets you free both hands and can be more comfortable than the skull crusher that is commonly included with PVS-7s. Recommended if you are going to be moving around a lot in the dark and need hands free. A good mount will let you flip the NVD out of the way. The pricing for these can be all over the place, but get a good one if you really really think you are camping and want to move around in the dark with hands free.
Again, I know that most people on CN may only think about NV as an astronomy tool, but NV is cool and powerful tech, and extending that tech can be inexpensive and useful.
Hope someone finds something useful here.
