What range do the eyepieces have for width adjustment (eg 35--55 mm)?

It comes with two eyepiece sets. I don't see a mm setting. One eyepiece says WF 20x . The other eyepiece says WF 10x/18. I did a little research online, and apparently /18 means 18mm. I'm not sure what the 20x eyepiece is. Until my son because interested a couple years ago, I hadn't used a scope since my college biology GM course; and now I'm learning along with him. I suspect life science majors, grad students, and professionals will need to buy better eyepieces. But these have been great to show my son prepared slides and teach him to be aware of a microscopic view of our cosmos. Hopefully our interests will lead us someday to considering better eyepieces in a year or two. But, if you're looking for more now, you may need to budget that into their purchase better eyepieces. Or you can contact the business and see if they would replace these eyepieces, add better ones, and for what price. This has been my only business with them, but they were remarkably attentive and responsive to this novice user.

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

Not sure how to answer as I'm inexperienced with scopes so far. But here are some dimensions from the manual:Eye relief: 3.8inobjective tube diameter: 1.67ineyepiece outside diameter: 1.73 inlength: 11.5inMounted with good clearance using medium profile rings on #12 weaver mounts. Not too close to existing folding rear iron sight. I hope that helps.

Yes. I have wide set eyes, and have shared my binoculars with children. I can assure you these will adjust easily for a good range of eye widths.

No idea on the parallax setting. The eyepiece rotates at the rear to focus at different ranges. Hope this helps.

Michael, Not sure exactly how much 1.2 is, but the adjustment is fairly large on the right eyepiece both + and - As a test .. I set the right eyepiece at max (-) and used my reading glasses 1.75's in the eyepiece to bring the field back to normal focus, ie left in focus, right at max - and the 1.75's on the right bring them both back to even focus. They are great binoculars and they perform very well for the weight and compact size. Hope the info helps.

30mm is correct. I confused another Bushnell scope with the one in question.

I found this specification: 3.6mm Lens with Viewing Angle of 75°. As others have stated, it is wider than what is commonly found. For the cost, I was not disappointed.

1.25 inches, it is the diameter. You need an adapter to used it in your telescope or a 0.965 inches eyepiece.

Very easy. You will need to purchase 2 inch visual back. I actually ordered the CPC 925 and the two inch eyepieces work very well with that.

Hi Robert, There are many many choices of eyepieces that have larger exit pupil and wider apparent fields of view that give more of a "window" like view rather than a "key hole" view. Celestron has their next line UP in quality called X Cell eyepieces in several differnt magnifications you may consider? We would love to earn your business!

Stated eye relief is 4.0 inches, which is about average for this type of scope. If your set-up requires a truly long eye relief scope, there are better alternatives.

While the 71008 may or may not be adjustable the 71012 is from 25x to 100x. My purchase has been a real source of joy, excitement, learning and revealing! My children frequently use them for lunar observing. My wife loves animal watching. One suggestion if I may. Purchase a quality tripod! The glasses are not light and for higher magnifications a good solid mount is a must in order to keep your objective is sight. It's well worth the money! I hope this helps and I hope you enjoy your glasses witchever way you choose to go.

Yes they will. 1.25 is the size eyepiece your telescope takes. This kit comes with 1.25 accessories. I bought this kit & love it.

You will have to measure the outside of the scope (with a pair of micrometers) or contact nikon to get the outside diameter of the front objective and the eyepiece objective. Once you have those measurements you will need to cross reference to the Butler Creek chart.

I use the 3 and higher for imaging Planets, thet 2X can be used for doubling the power at the eyepiece. The 127 eq is a great scope you should have lots of fun. I had a C5 at one time loved it.

Yes, but lenses wider than 35mm are a little soft in the corners. That's more of a sensor issue though.
