Shopper : Why Did You Choose This?DENNIS S : My telescope came with two eyepieces, a 25mm and a 9mm. The 15mm eyepiece provides a magnification between the two. Combined with a Barlow the 25mmm, 15mm and 9mm provide 6 incremental steps of magnification.MAREK M : Simple low cost eyepiece to use with Baader flip mirror configuration.JOHN M : Provides just the right amount of high power magnification for Lunar and Planetary viewing. Any more is a bit too much.Michael D : I'm experimenting with CMOS imaging and am looking at options for enlarging image size

Eye Candy!

I needed a quality built low power, wide field eyepiece for my new 9.25" Edge HD OTA that also wouldn't break the bank. This 56mm eyepiece fits what I have wanted. My eyesight isn't as good as it once was so I hope this 56mm eyepiece will make viewing the cosmos more efficient. We have had a pretty lousy late winter/early spring as far as cloud cover, wind, snow and rain showers and I haven't had any real opportunity to view through this eyepiece, What I can say is this eyepiece is much lighter than the 23mm eyepiece that came with my OTA. This eyepiece has made balancing my OTA easier.

Telescope accessoriies a great deal

The eyepiece I ordered arrived on time for Christmas and in good condition. Adorama carries telescope parts and accessories at a reasonable price. Recommended.

Nice lens

Seems to be pretty good. I have a 4 1/2" f:8. I haven't actually looked at the night sky with it, but the phone pole a half mile away comes in quite clearly. "High Voltage" sign crystal clear.

Good quality eyepiece. Yes, the field of view is a bit tight, but good for initial alignments/adjustments.

It did exactly what it advertised it could do

It did exactly what it advertised it could do. I did not like the original "finder scope (two small red dots of light) that came with my telescope. By decreasing the magnification of my eyepiece from 20 mm to 32mm I was able to ALMOST turn my entire telescope into a "finder scope". I only wish I had bought something like a 40mm which might have worked even better. But alll the 40mm I saw had a narrower field of view than ADORAMA"S 32mm.

Great planetary eyepiece for long refractors

Nice heavy, well made eye piece. I use the 15mm on a 60mm f13 scope, as my planetary eyepiece. The Images are crisp, edge to edge. Also great for splitting doubles.

Good stuff

This was an easy and inexpensive way to modify our telescope. My 3yo loves that he can now see clear views of Jupiter and it's four moons. The site was easy to explore and the next time I look to upgrading my telescope, we'll be back.

Nice finish but optics is not match up

It has a nice finish overall but the optics is less then desired. For the price meade 4000 series 40mm possl would perform better then this.

Decent quality for the price

The quality is ok for the price, but the angle of view is quite small (barely covers the moon) and with the celestron cometron telescope, I have to keep adjusting the position of the telescope which causes shake all the time. If your telescope's mount is alt-azimuth mount, then this is the problem with such a small angle of view.

Excellent customer service

I ordered a Meade laser collimator and was informed that it was on backorder. I called customer service and was able to modify the order. Adorama made the process quick and easy. I have a high level of confidence in your company. You will be my first choice for any future purchases.

Pinpoint star images

Yes. Nice crisp images to the edge. I can wear my glasses with the long eye relief so I don't have to take them on and off when looking at info from my goto hand controller.

Plossl Eyepeice with some flair!

Great upgrade to the eyepieces provided with my telescope. Had to get a special adapter for my digital camera use but may well be worth it based on my naked eye usage so far. Bright and sharp to the eye.

Great Eye Relief for Eyeglass Wearers

I am using this eyepiece on a Celestron C70 for terrestrial viewing via the standard eyepiece adapter supplied with the C70. This gives me a bright clear image with a magnification of about 18. The feature I like best is the long eye relief because I wear glasses. This eyepiece is longer and heavier, however, than the zoom eyepiece that comes with the C70.

I recently purchased this item for my Celestron NexStar 5 SE telescope and I was impressed with its construction and optical quality. It performed well even in the light polluted area of Bergen County where I reside. Also the price was right when compared to other vendors.

Celestron 40mm Omni 1.25 Plossl Eyepiece

I enjoy using this eyepiece for viewing nebula, galaxies and other relatively large field objects. It produces a nice wide crisp view. It is also handy when trying to locate objects before upping the magnification.

Great planetary eyepiece for long refractors

Where astronomy enthusiasts and stargazers seek to elevate their celestial viewing experience, the 15mm Omni Series 1.25" Plossl Eyepiece stands as a superior choice. This high-quality eyepiece, designed by the reputable brand Celestron, offers a broad spectrum of enhanced features across a variety of focal lengths.

The Omni Series is a testament to Celestron's attention to detail, with design elements specifically crafted to optimize user experience. At the heart of this eyepiece lies a 4-element premium symmetrical Plossl optical design, renowned for delivering crisp, edge-to-edge images of stars, planets, and other celestial bodies.

One of the key features of this eyepiece is its blackened lens edges. This thoughtful design element serves to minimize internal reflection and maximize contrast, providing you with clear and vibrant views of the cosmos.

Further enhancing the viewing experience, each lens surface is treated with a multi-layer coating. This specialized coating is designed to maximize light transmission and contrast, ensuring that every celestial object you observe is displayed with exceptional clarity and detail.

The Omni Series eyepiece also undergoes a two-step anodizing process, a feature that sets it apart from many other manufacturers. This process effectively prevents reflection from the top eyepiece barrel, eliminating potential distractions and enhancing your viewing experience.

Finally, the eyepiece comes with threaded barrels that are compatible with 1-1/4" Celestron thread-in filters. This versatility allows you to customize your viewing experience according to your specific needs and preferences.

In summary, the 15mm Omni Series 1.25" Plossl Eyepiece is a durable, reliable, and affordable choice for those seeking to enhance their astronomical observations.
