I was pleasantly surprised when I opened up the pkg. This eyepiece had a couple of features that are not shown in the photo. It has a rubber eye guard and the zoom ranges are marked at 8,12,18,&24mm. It also comes in a very nice hard plastic case with a screw on top. The optics are very nice for this price range. The zooming feature allows you to determine how much magnification is usable with your seeing conditions. This really allows you to maximize your viewing time. I found the zooming to be extremely smooth (with no clickstops) and almost parfocal throughout the entire range. Only slight focus adjustments were needed in the higher mag range. I found the eye relief to be extremely comfortable(very pleased with this). I was really surprised at how well it barlowed. Using my 2x and my 1200mm fl scope I was able to get up in the 300x range without much degradation of the image. (first time I've been able to actually see festoons and swirls in Jupiter's cloud bands). Overall, I'm very pleased with this eyepiece. It exceeded my expectations and I can see that some nights this may be the only eyepiece that will be used. It is an excellent EP for the beginning or intermediate level astronomer. And the price is right!

In order to appear objective here, I'll try to list some cons with this EP. Keep in mind that I really had to think long and hard to come up with these, as I didn't find that they were that big of a deal to me. So here goes. The eye guard is a stiff rubber and didn't completely block out stray light from a nearby street light. No biggee there. I'll just use a different viewing spot. At the highest mags, I did noticed some very slight distortion at the very outer edge of the FoV (but not as bad as I expected). At the highest mags the 40° FoV is narrow but again not as bad as expected. While the views aren't as clear as a fixed fl EP the benefit of using just one far outweighs the difference in my opinion. For ease of use and pricing, you can't go wrong with this EP.

I purchased the Celestron 8-24mm zoom eyepiece instead of buying multiple eyepieces for my Bushnell 100mm Mak-Cass. Since this eyepiece costs roughly as much as a single fixed eyepiece, I figured it was a decent purchase. As a beginner, I find this to be a bulky eyepiece, especially in comparison to the 25mm one that came with my scope. It feels like a small SLR lens when held. Not shown in any of the manufacturer images are the markings on the side annotating a few key zoom focal lengths including 24mm and 8mm as well as two inbetween. As well, as mentioned by other reviewers, there is a large rubber eyecup that has been rolled down in the image. This rubber is relatively soft and is easy to roll back up or down. The zoom motion is relatively smooth, and can be done with one hand once the eyepiece is screwed in place. The field of view is reported as 40-60 degrees- it appears that at 24mm it is at 40 degrees and at 8mm it's 60 degrees. The field of view is limited at 24mm, but is acceptable for me- objects will stay in the FOV for a while. Unfortunately, when it comes to optical quality, this eyepiece is below par. It offers grainy views, even at 24mm, and these only worsen by 8mm. I find it hard to obtain clear views, even at the best possible focus setting of my telescope. The eyepiece is not as good as the 25mm eyepiece that came with my telescope, and that is an average eyepiece. While I enjoy using this eyepiece and find it extremely convenient, the views offered at higher magnifications simply do not reveal any higher level of detail than my eye could discern at 24mm- they just make views bigger. I would recommend this eyepiece for travel purposes, but not for long intense viewing sessions.

    Comments about Celestron Zoom Telescope Eyepiece 8-24mm - 1.25 Inch Format:

    The Celestron variable Zoom Lens is a handy addition to anyone's tote box of treasures. The Eyepiece is finely crafted, weighty; and the Optics are good enough to shoot some of those badly needed extreme zoom shots. The eyepiece protector "pops off" exposing T-treads for a DLSR. Any standard T-ring will adapt; merely screwing on with near to perfect projection for the camera. Handy. It's also shipped within a very nice full coverage case, holding the eyepiece firmly with field protection. Try one, you'll be glad you did.

      Comments about Celestron Zoom Telescope Eyepiece 8-24mm - 1.25 Inch Format:

      I purchased my zoom eyepiece from oc telescopes in santa ana. I didnt want to wait and i wanted to actually holded and test it before i buy. Anyway, i was really and truly amazed by celestrons zoom eyepiece. My 70mmx400mm refrator telescope/spotting scope originally came with the cheap plastic eyepices. 12.5 and 4mm. As soon as i put my newly purchased eyepiece the apparent field of view (afov) is just amazing. I dont have to strian my eyes nor do have to have my eyeball literally planted on the eyepiece. The best part if i see some thing i want to look at closer i just zoom right in!!!! Lol dont have to change to another eyepiece. Although the more you zoom in the dimmer the object gets but thats just normal.
      I mostly use it for terrestial viewing by the back bay and the clearity and detial i can see is just phenomenal. Everything looks like in HD. lm really happy with it and would buy again if i had to. Maybe a se ond one with a bino viewer. Lol!
      Its solid all the eay thru and thru. Threaded. And comes with its pn plastic case with end caps.

          Perhaps it's because I'm using it with a 90mm spotting scope but it doesn't seem to let in enough light for celestial viewing.
