Are these nitrogen purged? Is there only one adjustment in the middle or is there one for each eyepiece?

These are nitrogen purged as are most quality binoculars. Some manufactures now offer argon purge but genrally considered higher cost with minimal additional benefits. There is a single adjustment in middle for both tubes. The right eyepiece has the fine focus so that you can adjust for vision differences between you eyes.

There is an adjustment on one of the eye pieces. I don't know about the nitrogen issue.They are lightweight and very fine optically.

I think they are nitrogen purged. There is the standard single adjustment in middle, and then the right eyepiece has the fine focus so that you can adjust the binos for varying vision in both eyes. I am a birder for work, and I love these binos.
245
I feel sure that they are nitrogen purged. There is a central adjustment where you close the right eye and focus, then you close the left eye and focus by the eyepiece adjustment on the right eyepiece. I like the binoculars.

Once you have the right eyepiece set for your vision there is the standard single adjustment in the middle.

Yes, they are nitrogen purged, according to page 7 (english section) of the Monarch 5 Instruction manual which covers the 8x42, 10x42 and 12x42DCF models, it states, "Nitrogen-filled design makes them resistant to condensation and mold." Your second question has already been answered, but yes, there is a central adjustment that affect both eyepieces simultaneously while the right eyepiece has a secondary adjustment. This allows you to, if necessary to adjust both eyepieces to different foci. Additionally, both eyecups rotate and ratchet outwards which guides your eyes into the right distance from the eyepiece that allows easy full field view. These binocs are excellent and I love them...

Yes they are. Plus O ring sealed to be 100% fogproof and waterproof. I have purchased a pair and can tell you that I'm very happy that I did. These will perform as well as much more expensive models.

I don't think it's either. There are just just rubber rings around the eyepieces. They extend about ¼ inch beyond the eyepiece.

Hello, First issue is the use of a reducer/corrector with a barlow multiplier. The two lenses are working against each other to no effect. Use the eyepiece alone or use it with the reducer corrector for lower power (wider fields of view) or use the eyepiece with the barlow for much higher power (smaller fields of view). If you have the Celestron Edge telescope I do not believe the reducer/corrector will work correctly. Hope this helps.

I was able to fit in my smaller eyepieces in the adapter. There is a knurled screw that will hold the eyepiece in place. I've also found that it isn't designed to be used as a primary focus adapter unless you have a low profile focuser. Has anyone been able to find any larger eyepieces that will fit in the adapter?

The aperture or the focal length of a scope have no bearing on the eyepiece used.They will work just fine on yours.

Hello Patty, Honestly I dont know. It might have to do with the total focal lenght, I ran into a problem with attaching a reducer then the diagonal then the bifocal then the eyepiece, and i could not focus properly. You best bet is to call Celestron on Monday, sorry I could not help more, Jim

Yes, the eyepieces have 2 positions; they snap in for glasses use, snap out for naked eye use.

I bought the moon filter at 1.25 but it is too small. The eyepiece is 1 5/8". When I put the moon filter into the eyepiece, unless I am doing it incorrectly, it does not sit in the center of the eyepiece (eyepiece too big for the 1.25 filter).

There are no threads to secure filters on the front. To protect the lenses I use (2) "Vortex Optics Flip Cap Optic Cover, Size 7". They fit great!

The lense are auto adjusting. But only set at 10. The helment is adjustable from the distance to your face. I havent tried the respirator yet.

Laser has two set screws - up/down and right/left. Spring loaded screws very easy to adjust. I bought a 2nd one after I tried out the 1st. Don't know about the nitrogen. Bill

No it does not, however when using eyepiece projection you can attach the filter to the eyepiece.

Each eyepiece is independently adjustable and once set, only need minor adjustment for a sharp view depending on distance.

I don't know for sure if there are. I haven't seen any. I used to get a soft chamois eye cover for my old Arriflex 16mm eyepiece but they would be too small to cover or replace this eyepiece.

You will need to purchase a adaptation set. I previously had one for other lenses/filters, so it wasn't a problem, but I can see where this might be frustrating if you did not have these.

No they are not, but they do show the number of turns up or out from the stop with lines parallel to the body of the scope. For the price, there aren't too many zero stop scopes out there.

I have found there is really no proper way in how to focus the eyepieces. You just have to keep adjusting them, mess around with it until they are adjusted to your satisfaction. I wish I could help your more, but thats really all I can say.
