Please advise the internal diameter of ocular tube? and can be replaced by a digital eyepiece and connect to computer via USB to view the picture on the screen? Best regards / Jim

Jim,THe internal dimension of the eyepiece holder is 1.215 inches.It is threaded on the outside of the tube which is very short and made as part of the spotting scope.This scope probably will not work for what you want to do.The eyepiece screws in on the external thread,however the tunnel inside the eyepiece tube is only .800 inches deep before you encounter the mirror.If you need photos (closeups)contact me at gaiginsteve@gmail.com and I will send you a series of closeups of the ocular area.Hope this helps Steve

The diameter is 1.25". The focal lengths are 20mm and 10mm, but those are used to determine the magnification, while the diameter is the width of the eyepiece barrel. The 1.25" is considered standard size, although you can buy 2" eyepieces for much more money. Most telescopes accept 1.25, but the pricier ones accept both 1.25 and 2 inch diameter eyepieces.

Used a eyeglass screwdriver kit (local hardware store or local optical shop). A jeweler's screwdriver kit would work as well. Definitely need the correct size phillip's-head screwdriver (bit). Hope this helps.

I was pleasantly shocked and surprised when I simply pressed my Phillips desktop computer cam up to one of the eyepieces. I was Skyping with a friend and he saw the specimen very clearly! WOW. I would imagine that I can simply set up a mount over one of the eyepieces and take photo snapshots AND/OR videos of anything I wish to observe.

Mika said yes. Mika has done this. I have not tried but the red hole is about 2.5mm and the white hole is about 1.5mm (This was an eyeball measurement without a micrometer.)

Thank you for your response Darrell, this discussion board seems pretty much dead so I thought I would never get answered, but I did, and a great answer at that.I've been thinking about buying the Orion XT4.5 now, I'm aware the image will not be as great as the 8 inch but I'll still be able to see Saturn right? Would this be better than a refractor telescope? Sorry for all the questions! No more questions after this, I promise.

Forget about this. It's a piece of NOTHING.. visiion is much worst.. mine came uncalibered so it's impossible to use both eyes... it worth what it cost.. hehe

Sorry I could not get an accurate measurement of the eye piece. I could measure the male end on the scope. It measured 1.614 inches and there was another that measured 1.364. Hope this helps you.

There's an insert for 1.25" which can be removed for 2" eyepieces. Also, the telescope only comes with a couple of 1.25"...or at least that was the case when I purchased.

This is not an long eye relive. They make a 2-7X44 that is a long eye relief.Model #SCP3-274LAOIEW.I can't answer the last question. Sorry.

It will fit most microscopes after you take the eyepiece out, personally I would not waste the money on it as the software that comes with it is really a sad affair. The image you get on the computer is only about 3" square that makes finding focus very difficult. I would have returned it but kept it to long. I am presently using a 16mp point and shot camera with a home made adapter that is getting beautifully focused images under all powers of magnification. Good luck

You can put a Celestron 93230 8 to 24mm 1.25 Zoom Eyepiece in there and it works.I did it today works great can zoom until there is no vignetting.

Very, very likely. I bought the OMAX 40X-2000X Lab LED Binocular Compound Microscope with Double Layer Mechanical Stage and Coaxial Coarse/Fine Focusing Knob in Dec, 2012, which is awfully similar to the one you asked about and about the same price. The eyepieces look nearly identical, which is all that matters for this question. The Celestron works great with mine--I love it. You may want to search for my review on the Celestron for a few tips regarding getting it to work on a computer, etc. Good luck!

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.

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

Inside diameter of extender is about 1.5". Measure the diameter of the tube with the eyepiece set screws. If it is about 1.5" you are all set. The extender has to slide over your eyepiece and clamp in the same area where your eyepiece set screws are.

I use them at my computer since it is somewhere between the "distance" and the "reading" of my bifocals, but I don't think they would work in your case. Try maybe some magnifiers that you can wear on top of your glassesHead Wearing Magnifier Can Be Used Hands Free And Worn Over Glasses. Has Dual Magnifying Power.Also, tool suppliers provide such magnifiers for close work like you describe.
