It is not clear, is this a 1.25 inch, or two inch device. On my C11 I have two inch eyepieces, will this fit? (the original C11 could only take 1.25.

The reducer corrector attaches directly to the real cell of your telescope between the cell and the eyepiece adaptor. My C8 is an early one with a 1.25 eyepiece adaptor and there was no problem with the attachment. Hope this helps.

This screws into the rear cell of your C11. Then you attach the 2" diagonal that is made for sct's. Then if your using 1.25" ep's then you'll need the visual back that Celestron makes for the 2" to 1.25 ep's. The other option if you own a 2" diagonal that isn't made for sct's its just a regular diagonal then you'll need a 2" adapter that has a threaded end and an end you slide the diagonal into and tighten with a thumb screw. Hope this helps

This Focal Reducer will screw in where the back is. You unscrew the back, screw this on, then screw the back back on. Also, this is really designed for Astrophotography. It will work for visual use, but most people get this for AP.

It can work with either 1.25" or 2". It goes on the telescope first then your lens adapter, either 1.25" or 2" attaches to it.

As Daniel said, it will be compatible with any 1.25" eyepiece. Looking up NexStar 4SE, I see it comes with a 25mm focal length Plossl eyepiece. The X-Cel eyepiece you've asked about is also a 25mm, so you probably don't want to duplicate the focal lengths (unless you're looking for a little wider field of view). I think you'll want to get a shorter focal length - 18mm, 12mm, 9mm, etc - to get more magnification. Divide the focal length of the telescope by the FL of the eyepiece to get the magnification. In this case 1325mm / 25mm was giving you 53X. I have several of these eyepieces and like them. As Daniel said, it will be compatible with any 1.25" eyepiece.

Mine works well with the Orion 15x70, so yours should be fine in terms of size. However I am not familiar with where the screw fits on the Celestron. Advise you to compare the two binoculars. You can always return it if it doesn't work.

At first blush, it appears your Celestron has an eye piece of .98 inches in diameter. The Barlow you are looking at is designed to fit an eye piece of 1.25 inches. If you can find an adapter possible. But may not be the purchase for you.

Celestine has its own adapter specific to telescope devices so you might want to check on the Celestine site first. Outside of that a 1.25 inch standard eyepiece will work fine although my wide field of view 52mm erffle barely fits.

Measure your eye piece if its 1.25" that's 1" & 1/4" inches. If yes then yes. If you are on computer then go to google, type in your model and in the info it pulls up it will say the eye size. Hope this helps.

My XT8 came with the 1.25" eyepiece so all 1.25" accessories I know of will fit. This is a good item to view the moon because the moon is too bright especially as it's waxing to view it comfortably. Just be sure to take it off when you are looking at anything else, you won't see anything. I forget this sometimes and can't figure out why I can't see any stars or planets. :)

Almost all telescopes use 1.25 inch or two inch eyepieces, and this are 1.25inch, but even the one with 2 inch can use this EPs with an adapter, so answer is YES!

This should work with any telescope that requires standard 1.25 inch eyepieces. They should also work with any telescope with 2 inch eyepieces, provided you purchase an adapter. I use them on an Orion Skyquest XT6 and have no issues.

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.

I think they will not fit in the barrel of the Universal Adapter, only 1.25 inch eyepieces that has nearly the same diameter in both ends. Here´s the specificacions offered in the Orion wep page: "Since the Universal Camera Adapter features an inside diameter of 38.6mm, you can insert any 1.25" telescope eyepiece that has an outer housing diameter of 38.6mm or less". Hope this was helpful for you!

It will work with any standard 1.25 inch eyepiece adapter or focuser, but i second the previous answer regarding tracking. I suggest downloading Stellarium (free planetarium software) and entering your telescope and the sensor specs into the telescopes plugins so you can see what the field of view would be in you 80 mm, and how quickly objects move out of that field of view. If it's too small, and you don't have mount that is tracking the sky, you might end up just being frustrated.

It should work with any telescope that accepts 1.25" eyepieces. However, a diagonal such as this is almost always *included* with the telescope, so unless you lost yours, there's no need to buy one.

This specific camera has both a thread to fit guide scope or attachment that adapts to same OD as a 1.250" eyepiece which fits your focus assembly. No direct connection over a eyepiece.

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.

I actually don't know. But I believe that all modern eyepieces are standardized to 1.25 inch so this star diagonal should work.

Yes, the Nexstar 4SE is compatible with any 1.25" eyepiece including this, but it will not fit 2" eyepieces.
