Can someone please measure (in mm) the diameter of the visible lens area? Just the glass area, so I can know how big it is... Thank you!

I didn't measure but the glass part is about .5 inches. The lens is very small and very sharp.

Sorry, I don't have the lens any more. But I can favorably comment on it's sharpness, color and contrast; a winner.

The lens are about 8 to 9 inches in diameter. I do not know if you can purchase the lens separately. I would contact "Hella" on the web for that answer.

I believe the measurements are listed in specs in the ad but I measured mine and the lens surface is 2.25 wide by 6.5 inches long.

Michael - Thank you! Thank you! Thank you! I just educated myself on the 10-22 mm and decided that is the lens for me! Now to save up... :)

The lens should indicate what filter diameter it uses. Look for a symbol like an O with a slash through it, which will be followed by a number. That number is the filter size in mm.

Measure in millimeters across the inside diameter of the outer front ring of the lens.

I'm estimating about 2.5x to 3x. For higher magnification, you may have to go for a smaller diameter. I like the wide field of view the 4" glass gives. It's a beautiful magnifier and comes in a very nice box (in case you have gift-giving in mind).

Here is Aleksandr K. again. Look at some pictures I made using Celestron 5 MP (their sizes were reduced).https://www.facebook.com/media/set/?set=a.586148731439698.1073741832.100001337299954&type;=1&l;=b176410e3f

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

The lens itself is 4.5mm at wide and the listed 35mm equivelent field of view is 25mm.Sorry, N. Hoang; I didn't see that you had beat me to it.

The diameter of the lens cap is 3.5 inches or 6.25 cm. There is not a size stamped on the lens cap

I just got one and couldn't see anything either. When I took it out of the box there was a 3" lens that was separate. I thought it was an extra. Turns out that it needed to be placed in the end of the telescope. If this is your case, unscrew the plastic ring at the large end of the telescope (remove the sun shade piece first) place the lens on top of the other lens and replace the plastic ring. There should be 2 lenses at the end. Once I did that I could see great! Start out with the largest eyepiece (25mm) to find objects easily.

You need to look at the threads in the front of your lens. There will be a notation of the size required there

The outer diameter of the eyepiece is 1.25" or 1.25 x 25mm = 31 mm approximately. Another issue to keep in mind is that this eyepiece is not a lightweight, and therefore not suited best for really light scopes.

They are about the size of half of a tissue. I usually need two to clean each glasses lens well. Hope that helps.

I assume you mean the bifocal area which is 1 inch diameter. The diameter of the magnifying area is stated in the item description.
