Celestron OMNI-XLT 127 overview

  • 1Description

Celestron's Omni XLT 127mm f/10 Schmidt-Cassegrain EQ Telescope is ideal for users who want a compact and powerful observation platform that is able to achieve high magnifications for detailed views of the moon and planets as well as the ability to reach out past our solar system to discover deep-sky objects such as nebulae and galaxies.

The Schmidt-Cassegrain design, coupled with the proprietary Starbright XLT optical coating system, corrects aberrations like comas and chromatic aberration to produce clear and crisp, high-contrast images with true color rendition. For its compact 11" length, it features a long 1250mm focal length giving it a high magnification potential, and its large aperture ensures the resolution required to see dim deep space objects that smaller apertures are unable to see. The scope is outfitted with an internal focusing mechanism which accepts the included 1.25" 90° star diagonal. Celestron includes a 25mm eyepiece that yields a moderate 50x magnification to get new users started.

The included manual equatorial mount features large slow-motion knobs make it easy to track objects even while when wearing gloves, with setting circles on both axes for alignment and celestial navigation. The Omni mount includes a Vixen-style dovetail for mounting other optical tubes, and an adjustable-height stainless steel tripod with large and sturdy 1.75" diameter legs and an accessory tray that acts as a leg spreader for the tripod to add stability and reduce vibrations.

    Omni XLT 127mm f/10 Schmidt-Cassegrain EQ Telescope is rated 4.6 out of 5 by 12.
    Rated 5 out of 5 by from Excellent Scope I'm Very New To Astronomy,But This Scope Has Delivered As Promised,Got To See Jupiter And It's Four Largest Moon's,The Lunar Landscape Just Jumps Out At You,I Only Have 2 Eyepices So My Range Is Very Limited,I Look Foward To Purchasing A Televue Barlow Lens To Enhance My Viewing,I'm Sure With A Barlow This Scope Will Provide Some Awesome Images,I Don't Have Anything To Compare This Scope To,So I Have To Go With What I've Seen,As A Novice,This Is A Great Fit For Me,I Would Recommend This Scope To Anyone.....And Kudos To B&H For The First Rate Service.....I Look Foward To Many Great Night's Of Stargazing With My New Instrument,BTW Celestron Rocks.....

    Rated 3 out of 5 by from Superb optics but poor Equatorial Mount I purchased the Omni 127 which features the venerable and highly regarded Celestron 5 f/10 optical tube assembly on the CG-4 Equatorial mount. The 5-inch optics can only be described as extraordinary, some of the finest I have used in a half century of observing. But ironically, the superb optics are hampered by a mount that is nowhere up to the quality of the optics. That's why I gave it only 3 stars overall. I'd give 5 for the optical quality by itself, but only two for the mount. I would highly recommend the tube assembly to a friend. I reluctantly returned the entire instrument and am looking for the same 5 OTA on a better mount.

    Rated 4 out of 5 by from Outstanding Value Intermediate Telescope I Bought this telescope as an upgrade from a beginner 3 Reflector with a wobbly Alt-Az mount. First off, the mount for this telescope is a beast (in a great way)! Heavy duty and stable, which comes at the cost of weighing a lot, but the best optics are rendered useless with a bad mount so it's well worth it. The slow motion knobs work well, but it's difficult to tighten the cables onto the keys. The OTA is quite nice and a great value for the price as there is a large jump to go much larger than 5. Overall an amazing value to enter into the intermediate realm of astronomy with the potential to add nice eyepieces, filters and motorized drive. Also need to get a nice hard-sided case for transport to make this a truly mobile telescope.

    Rated 5 out of 5 by from Omni XLT 127 5.0/127mm Great for a starter, complete kit easily assembled for viewing stars quickly out of the box. Tripod is very heavy and strong providing an excellent base for the telescope.

    Rated 4 out of 5 by from Great closeout price Half of the price covers the HD CG-4 German Equatorial Mount & 1.75 Steel Leg Adjustable Tripod. There are few solid tripods of this quality at this price. A motor can be added later for under $. The optical tube is about average for a 127cc. The poorest part is the view finder, with a poor mount that means repeated alignments are necessary. It is worth every penny if you are a fan of Celestron. You can buy the tripod separate and go with another optical tube of better quality for the same price. But either way you end up with a great value. Not everyone uses the go-to features that keep driving the prices up. So if you don't mind manually screwing across the sky, this is a great buy. All in white, it even looks pretty enough to make your wife stop complaining about all the money you spend on sky watching.

    Rated 4 out of 5 by from Fantastic grab and go scope Wonderful G4 mount for any scope and this is a great grab and go scope. Compliments my 10 inch dob for portability perfectly. Not a professional level photography scope but have already seen the great Orion Nebula and jupitor first night out in Boston. With better seeing conditions I can only expect this scope will be better than I expected.

    Rated 5 out of 5 by from Nice optics good price I bought this scope to view planets from my window. Very versatile and easy to maneuver unlike other styles. Just need extra eye pieces as it only comes with one. B&H had the best price and were fast with shipping.

    Rated 5 out of 5 by from Awesome Bang for the Buck Just bought the XLT 127 from BH. Great value. I use this scope for casual observing and astrophotography. This is my second scope, the other being a 80mm refractor with horrible Chroma (purple fringe). This scope has no chromatic issues and is easy to use with one caveat (see below). But first the good. The mount is awesome, almost no vibration, slews easy and supports the scope and my OMD EM5ii with only one counterweight. Tripod set-up is easy compared to an EQ1. Once assembled, it weighs about 30 lbs, but that weight is good for stability. Large knob-levers make it easy to adjust the RA / DEC clutches. It even has a polar scope port (of which I just installed the polar scope in about 2 minutes..haven't aligned it yet...cloudy) Supports the compatible auto tracker (not finder). Easy to install as well. The scope, great magnification right out of the box, with barlows and various eye pieces I have seen Jupiter, Orion's Nebula, with no issues, and they are huge in this scope (2x Barlow and 9mm eyepiece) Just be aware, at that magnification, you will have to slew a lot to keep them in the field of view. (or get the tracker). The one caveat, and it is not fault of the scope, is that it may need to be collimated (adjusted) when you get it...you won't know until you use it. If you can't focus and all you see is blur or blobs of light that are not crisp, then you need to adjust. This is not a bad thing, it is just a requirement of reflectors and their variants. I didn't know this and expected clear images out of the box :( With a little searching on how to collimate, the process is pretty straight forward, but will test your patience if you were expecting maintenance free. It is as easy as adjusting 1,2 or 3 screws on the front lens. Be patient, methodical, and slow. But doing this allows you to know your scope a little more. Again, BH offers a great scope / mount at a great price, especially if bought individually. You won't go wrong!!!
