Celestron Omni 4mm Eyepiece - 1.25”

Looking to build your astronomical eyepiece collection? Get started with Omni, a quality Plössl eyepiece with great views. Go ahead—add several to your arsenal.

FEATURES AND BENEFITS


4-element Plössl design

This classic astronomical eyepiece features the very popular Plössl optical design. Inside, four glass elements perfect the image, each one fully multi-coated with high transmission coatings for brighter views.


50° field of view

Perfect for viewing the Moon, planets, and a plethora of deep sky objects.


High-powered observing

With a focal length of just 4mm, this eyepiece offers high magnification to get in close and observe objects when seeing conditions are stable.

Compatible with 1.25” focusers & accessories

The 1.25” mounting barrel is internally threaded to 1.25” filters and adapters. It is also compatible with 1.25” star diagonals, focusers and Barlows.

Blackened lens edges

Unlike some other eyepieces, the edges of the optics are blackened to increase contrast.

Quality aluminum housing

The eyepiece’s main housing is machined from durable, high grade aluminum. The eyepiece also includes a removable rubber eyecup.

Two-step anodizing process

Each Omni eyepiece is finished with a two-step anodizing process that results in a beautiful matte finish on the exterior while reducing internal reflections and glare inside.

I got the 4mm eyepiece to use with a 114mm reflector with a FL of 500. At first I was skeptical, I read reviews and had many "experts" tell me it would provide too much magnification. I assume they saw 114mm and assumed the worst. This thing provides excellent magnification and produces a detailed image!

Full Review:
For people looking at this eyepiece there are 2 factors more important than the size of the primary mirror. The first is quality, I''m using an Orion telescope but there are other good brands out there. Is you are using a cheap barska or some other department store brand you are sadly wasting your time. The second most important thing is focal length. Based on my research the best a ground based telescope can do in magnification is about 300x simply due to the atmosphere. There are exceptions like remote locations and unusually calm atmospheric conditions but those will be rare occurrences. In my experience there will be times when atmospheric conditions won''t let you see much detail at 100x, that''s just the way it goes. Additionally if you want to get the best view of planets you want to wait until they are as directly above you as possible to minimize how much of the atmosphere you are looking through. So that said, to figure out a eyepieces magnification simply take your focal length and divide it by the size of the eyepiece. So (500/4 = 125x)... That is well below the scopes limit of 228x. You can figure out a reflectors limit by multiplying its size by 2 so (114 x 2 = 228). So the greater your FL the more magnification this will apply. This eyepiece will certainly give you more bang for your buck with a FL of 700 but it''s still great on the lower ends and I recommend it. Knowing what I know now the only way to potentially do better is get a 5mm and a Barlow 2x, I have the latter.

At 25mm, this eye piece is ideally suited for those wanting to view large chunks of the night sky at one time. Why is this important?

If you are looking to just explore, feel like your floating in space with the stars, and see what you can find in space, that is the type of eyepiece you want.

If you already know what you want to look at, say for example, Jupiter, then you want more power so you can see the storm clouds, and the moons. This may not be the eye piece you want.

I use a 7 to 12mm to see details of Jupiter, Mars, Saturn. I use 15 and 25mm to get lost in the night sky.

What''s the benefit of just getting lost in night sky with a 25mm eyepiece? The sudden surprise you get when you catch a satellite streaking across your view. The lump in your throat you will get when you are looking at the sky and you accidentally ''run into'' the Andromeda galaxy for the first time.

So 7mm to 12mm when you know your destination and exactly what you want.
12mm to 25mm+ when you want to just enjoy the journey of exploring.

I wanted the widest eyepiece I could afford that I could use with my Celestron Omni XLT 120 refractor. I purchased the 40mm version first before buying this thinking I will get the widest view because of the longer focal length. The 32mm eyepiece has an apparent field of view of 50 degrees whereas the 40mm has a 43 degree view. I had overlooked this but waited for both the eyepieces to arrive so that I can test it myself and compare them both in my scope which has a 1000mm focal length.

Both of them are pretty sharp but start getting slightly blurry towards the edges which is expected for eyepieces in this price range. The 32 mm has a slightly wider view than the 40mm. This might be because of the 1.25 inch format of the eyepieces which restricts wider views beyond a point. That''s why it makes sense to go for 2 inch format eyepieces which have larger openings for wider field of views provided your focuser supports it. What I noticed was that the 32mm''s slightly wider view was also slightly more magnified than the 40mms because shorter eyepiece focal length translates to more magnification.

I tested it in clear skies last week and the Pleiades cluster still doesn''t fit into the field of view with the 32mm but it still provided bright crisp views almost to the edges. The star cluster just spills outside the field of view but note that my scopes focal length is 1000mm which is not a wide scope.

The finish and build of the eyepiece is very good and the rubber eye cap is excellent and very useful if you wear glasses like me. Even otherwise, it acts as a shield preventing stray light degrading your image. The eye relief is good as well.

The conclusion - the 32mm is a clear winner here and I don''t understand why Celestron would even offer a 40mm version in 1.25 inch format. I am going to be returning the 40mm and I hope this experience helps others in making a decision if they are confused.

Before I got this I consulted customer support from Celestron about my telescope and he recommended this lens and the X-Cel LX 5mm lens. I got this one now and it works really well. Quick tip get the 20 mm lens to help you find the object the swan it out with this lens to save your self time. Once that’s done you can do the minor adjustments needed to focus and see these distant objects like I have.
Things to note my telescope is a Newtonian scope and has a focal length point of 900mm.

I tried the 5mm on my Powerseeker 114eq with 900mm fl. The FoV is just slightly better than the tiny 4mm (about the same magnification around 200x) that came with it but the eye relief is MUCH better which makes it a lot easier to use. It''s also brighter and has clearer details so I''m starting to use skyglow and UHC filters and have a mars filter on back-order.
My biggest problem was that the weight of this EP affects the aim of the scope when switching between an Omni series and the 5mm X-cel LX because of the weak tripod and equatorial mount. It''s about the same weight as the Omni 8-24mm zoom EP so I re-balanced the scope for these 2 EP''s. Also the focuser is pretty touchy with this much zoom and it was extended out farther than with the Omni. The tracking motor is needed at 200x too or you''ll be shaking the dials every 30 seconds.
I like it and it will be my ''planetary'' EP from now on. Pricewise, it''s hard to say if it''s worth the cost. I do expect to use the scope more with it so I''d have to say yes it is even for a $100 114mm scope. If I decide to upgrade scopes, it will surely be worth it.
I''d like to add that 200x with this size scope is the upper limit and requires clear skies. The next size down at 7mm (about 130x) might be better in less than perfect conditions.

Longer focal length eyepieces often get overlooked, especially by those just getting started in amateur astronomy. Most beginner astronomy kits (Optical Tube Assembly w/finderscope, mount, eyepieces) usually include two focal lengths to get you started: a 25mm and a 10mm. My own experience tells me that anyone who wants to start a successful observing run needs to have a 40mm eyepiece to perform field narrowing from finderscope to eyepiece. a 40mm may not exactly be an "observer''s eyepiece" except for the most extended objects, but it is an absolute must-have to narrow the field around a target. In fact, since I typically run several rigs at once at my college''s star parties, I found that I needed to have at least two of these eyepieces. I already had a Sirius Plossl 40mm from Orion, and the Celestron Omni is an equivalent (nay, nearly identical) optical stack to work with a second ''scope, so I wouldn''t have to keep hunting for a 40 when acquiring a target in the eyepiece. This is a great, yet often overlooked, workhorse eyepiece.

I recently purchased a Celestron 9mm and 5mm X-Cel LX eyepiece . I was quite pleased to find that each eyepiece came with its own Bolt case which are two semi clear plastic halves that slide together and lock to provide protection for your delicate eyepiece. Not many eyepiece companies offer this benefit which is too bad, because bolt cases are relatively inexpensive (the size required for these eyepieces would cost 4-5 dollars each)...However, they are only available thru a couple of companies i.e. Agena and High point Scientific and a few others.
My eyepieces also came with dust covers on both ends of the eyepiece... I also really liked the twist up eyecups which were easy to operate and seem to stay put. All of the internal surfaces were blackened and this eyepiece looks and feels very welll made including the rubber grip band that is mid body on the eyepice. Kudos to Celestron (who ought to mention the bolt case in their specs) for such a high quality eyepiece for such an affordable price.

I chose the the 18mm eyepiece as it gives good magnification for deep sky objects such as galaxies and planetary nebulae. My new telescope is a Celestron NexStar SLT 127mm. It has a focal length of 1500mm, so the magnification is 1500 divided by 18 = 83 times. The eyepiece is much better than the two standard eyepieces that came with the scope, both in field size, ( difficult to judge as the two that came were 25 & 9 mm.)and also field clarity, ( more easily judged.) I live in the north of Scotland where we are blessed with little light polution, however at this time of year, June, the skies never get dark. Despite this the 18mm eyepiece works well at spliting double stars i was particularly pleased to split Polaris, it has a fairly wide seperation of 18.4 seconds of an arc but the primary is very bright 2.0, and the companion dim 9.0. As the experience has been so good i intend to buy the entire range of Celestron X-Cel eyepieces over the next few years, without going below 5mm, ( my telescopes 300 times magnification limit ) making the 12mm eyepiece my next purchace. Philips " Stargazing with a Telescope " by Robin Scagell, says : "Top of the accessories list is extra eyepieces." I recommend the 18mm X-Cel LX Eyepiece. I bought the eyepiece from Amazon. It arrived promptly despite my remote UK location. Amazon are one off very few companies that do not add hefty postage charges to the Highlands and Islands of Scotland.

I have a Skywatcher 130p GOTO with the stock eyepieces. The X-Cel LX is such a HUGE jump in quality! Jupiter has never looked so good! And in widescreen! My advice is to buy this and then replace your ''stock'' 10mm & 25mm eyepieces too! If you get the right focal lengths you can ditch the Barlow and get full magnification without the quality loss. Great product, great service.

High-powered observing

The 1.25” mounting barrel is internally threaded to 1.25” filters and adapters. It is also compatible with 1.25” star diagonals, focusers and Barlows.

Blackened lens edges

Unlike some other eyepieces, the edges of the optics are blackened to increase contrast.

The eyepiece’s main housing is machined from durable, high grade aluminum. The eyepiece also includes a removable rubber eyecup.

Two-step anodizing process

Each Omni eyepiece is finished with a two-step anodizing process that results in a beautiful matte finish on the exterior while reducing internal reflections and glare inside.
