Is the eyepiece universal 1.25"?

Technically, no. Not ALL 1.25" eyepieces will achieve infinity focus. Eyepieces from Celestron's X-Cel LX line can definitely do so, so do those from Pentax. There are probably other brands that would also work--just do some research. The following information comes directly from Celestron: " The Regal F-ED series spotters have a 1.25" eyepiece holder and the OEM-supplied zoom eyepiece is easily removed from the scope by a twist of a knurled ring. Because 1.25" barrel-diameter eyepieces are very widely available, you can use other eyepieces with your Regal. However, not all eyepieces will work with the scope because of the design of the internal focusing and 45-degree prism assemblies. This places the image plane for the spotter's objective at about the back of the knurled ring. So the Regals have a small back focus distance. Eyepieces that have long 1.25" nosepieces or barrels (with field lenses recessed about 1 inch or more) generally won't be able to achieve infinity focus with the Regal spotters. Nor will 1.25-inch- type T-adapters or Barlow lenses work with the scopes. The OEM zoom eyepiece has both a short nosepiece and its field lens at all magnifications is close to the end of the nosepiece tube. Eyepieces that will work with the Regal will have similar physical characteristics. As an example, most eyepieces of the Celestron X-Cel series have these characteristics and will work with the Regal F-ED series."

It is a standard 1.25 inch EP. As noted in the other answers it may not be possible to focus correctly. The EP on the Regal scope works in my Lunt Solar telescope and the Lunt works in the Regal. In general though you will have to test it out. The scope is very nice. My first one had a problem with the focuser after 90 day replacement warranty ran out. Celestron took it back but it was about 2 months before I got a replacement. When it was working it was a very nice scope, and I like the replacement although I use my other scopes more.

Yes it is. But some other 1.25" eyepieces cannot be inserted far enough to focus to infinity.
1770077
Yes, it is. If you have any problems like not being able to insert it far enough, I am quite sure you have a defective eyepiece.

Yes. Make sure it matches your eyepiece and scope diameters - 1", 1.25", 2", etc

To tell you the truth I don't know...however I believe that the mounting flange (for lack of a better term for it) around the eyepiece is the same size on all Nikon DLSR cameras.

It should be compatible with any telescope that uses 1.25" eyepieces. It has markings for the focal length in mm, but not magnification markings in x (times). It's a very good eyepiece for the money, I was not disappointed with my purchase. It is heavy compared to non-zoom eyepieces, so if you have any balance or weight issues with your mount, factor that in.

No it will not fit a 1.25" receiver without an adapter (not included). You can get an adapter at some wallmarts Tractor Supply or Amazon.

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.

I don't see why not if the 70EQ will accept 1.25" eyepieces, it should work.

It appears that the 102 utilizes 1.25" eyepieces. If that is the case, then the Barlow lens should work well.

You will need a 0.965"-to-1.25" Orion Telescope Eyepiece Adapter to make this work. The cost is $22.99 plus tax and shipping.

Yes it will work. All that is important is the diameter of the eyepieces. They are either 1.25" like with this accessory kit, or 2". Also look at reviews for other kits as quality varies. The eyepieces in this kit are not particularly amazing. Find a friend with other eyepiece brands or designs and see how well they compare. I would suggest buying two really good eyepieces than a bunch of cheap ones.

Any 1.25 inch eyepiece should be compatible. A search indicates that series is 1.25", so yes. Should work fine.
1645077
Yes. It will. A standard length 1.25" Barlow would work just fine with this telescope as well.

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

I don't think it's either. There are just just rubber rings around the eyepieces. They extend about ¼ inch beyond the eyepiece.

This kit can be used with many other telescope brands that accept 1.25" eyepieces and filters.

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.

It comes with a single 25mm eyepiece, so to answer your question outright, "no". But the 25mm is sufficient for seeing moons around jupiter and the rings of saturn with little effort. You can easily see nebula and some star clusters on a 25mm. I bought the Orion 08890 1.25-Inch Premium Telescope Accessory Kit (silver) set to fill out and have a nice starter set. Hope this helps
