If I measured correctly it's 1.5 inches. Like I said I'm still trying to learn how to use it. I haven't had much experience with optics

2 5/8 inches. It works very well so far. I wish I could us it on other tele lenses I own.

About 6.5 inches long/width. 4.5 inches high. About 4 inches deep (lens when closed). Lens opens up to about 1 inch. Hope that helps.

The diameter of lens matters, I was able to purchase an adapter for a couple if bucks. Works great!

The C5 comes with a 1.25" correct image diagonal. To use 2 inch eyepieces would require a 2 inch diagonal however there would be some vignetting in the eyepiece as the opening in the rear cell is only 1.25 inches in diameter. Advise to stay with 1.25 inch eyepieces.

52mm diameter. And yes, it fits in with the standard front thread of lenses with 52mm.

Descriptions on the lamp said there is a 2x magnifier which measures about 5 inch diameter. There is a 5x spot magnifier which measure just about 1 inch diameter. You can see the 5x spot magnifier towards the on/off button area in the pictures whereas the 2x magnifier is the whole lens. Hope this help.

Yes. According to the online manual for your telescope it takes the standard 1.25" eye piece.

Her is two thoughts, 1st you can use a minus 1 and that may give you the rsange you want but I took the 2nd way which I purchased a -2, that way I can use the plus adjustment to get the proper adjust. Don't to purchase an eye cup for the corrective lens.

Yes. I used a standard ruler to measure mine, so it's approximate...but it is about 2mm thick or about 1/16" of an inch to my eye.

You must measure the diameter of your lens, and THIS lens is 39 mm (about 1.53 inch).

My husband's eyes are also close-set. He uses the binocs all the way closed. The distance between the center of his eyeballs measures about 2-1/2" ...the same as the eye pieces on the binocs. I hope this info helps

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.

This is the measure between each eyepiece and your eyes while you view a full image. This spec is particularly important to people who wear eyeglasses. With glasses , you'll need 11 mm or more of eye relief. Most manufacturers recommend that people who wear glasses roll down the rubber eyepiece collars for viewing. On the 10x25's that will be 18 mm. ( On 8x 25 it would be 10 mm. )
