Explore the Celestron 56mm Omni Plossl Eyepiece. 2" barrel, 52mm eye relief. Enhance your telescope's view. Shop now for superior optics!

The Celestron 56mm Omni Series 2" Plossl Eyepiece is a premium choice for amateur astronomers and seasoned stargazers seeking a high-quality, durable, and versatile viewing experience. This advanced eyepiece features a 4-element, fully multi-coated Plossl optical design, renowned for its ability to produce sharp, high-contrast images. With an expansive 47-degree apparent field of view, this eyepiece is ideal for immersing yourself in the vastness of the cosmos, offering a perfect balance of low magnification and a wide field that is essential for observing breathtaking deep-sky objects.Crafted for use with telescopes of longer focal lengths, such as Celestron's Schmidt-Cassegrains and EdgeHDs, the Omni 56mm Plossl is particularly adept at bringing to life star clusters like the Pleiades, nebulae including the Lagoon and Orion, and galaxies such as Andromeda. Its innovative design, featuring large lens elements, enables this combination of low magnification and broad field of view, ensuring that some of the night sky's most awe-inspiring spectacles fit entirely within your sight.The eyepiece's construction is a testament to Celestron's commitment to quality. The internal barrel is painted black and equipped with baffles to minimize internal light reflections, thereby enhancing contrast for a more striking visual experience. Additionally, the lens edges are blackened to further improve contrast and detail in your observations.For added versatility, the eyepiece's mounting barrel is threaded to accommodate 2" filters, allowing for customization of your viewing experience. It is also compatible with 2" star diagonals and focusers. Safety is considered with a notched barrel design, preventing the eyepiece from accidentally slipping out of the focuser should the securing thumbscrews loosen.Ergonomics have not been overlooked. The Omni 56mm Plossl features an integrated knurled rubber grip ring, ensuring a secure, non-slip hold even in the chill of night or when wearing gloves. The eyepiece is also designed with user comfort in mind, boasting a fold-down rubber eyeguard and a generous 52mm eye relief, making it a comfortable option for both eyeglass wearers and those without.In summary, the Celestron 56mm Omni Series 2" Plossl Eyepiece is an exceptional tool for anyone passionate about exploring the night sky, delivering a viewing experience that is as immersive as it is impressive.

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.

Eye Candy!

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

Telescope accessoriies a great deal

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.

Nice lens

Use it constantly. Great bright eyepiece.

Great useful eyepiece

good value

Lens

Works great. Nice sharp image. Will continue buying Celestron lenses from this company.

Lenses

I love this lense! Perfect for my Celestron telescope. You can see everything in the sky!

Amazing!

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

No complaints

This is a great little Barlow lens. It's easy to use with my 1.25 size eyepiece.

Very nice Barlow lens

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.

It did exactly what it advertised it could do

Good value

I was given a telescope from a friend.  We loved what we saw qnd wanted to see even more; bought a Barlow to double our enjoyment.

See More with Barlow

These rival the $ eyepieces. Great optics and nice eye relief.Try one, particularly if you wear glasses.

Excellent ocular at a very low price.

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.

Great planetary eyepiece for long refractors

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. 

Good stuff

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.

Nice finish but optics is not match up

Nice accessory for a telescope. Easy to use, well built, should give many years of service.

Good quality product

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.

Decent quality for the price

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.

Excellent customer service

i really love this eyepiece! it's perfect fot deep space

great eyepiece!

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.

Pinpoint star images

I use this eyepiece on my Celestron NexStar 6SE and it provides beautiful wide field views of stars and objects.

Very clear View

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.

Plossl Eyepeice with some flair!

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.

Great Eye Relief for Eyeglass Wearers

This lens is as advertised.

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.

It worksfor me !

I like having this piece, I use it all the time, and it's easy to use.

A GREAT accessory added to my bag!

this barlow is amazing. i haven't been into astronomy very long, but i have used a few other barlows from other companies. this barlow improves the clarity of even the most generic eyepieces. i could see saturn clearer than i have ever seen it before. will deffinatley recomend this product to anyone...

all the bells and whistels...

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.
