About Celestron Omni XLT 120mm Refractor

A premium optical system to explore the universe... The Omni XLT family of telescopes was designed to offer a selection of models with the quality optics and stable platform that serious amateurs can appreciate.

The new Omni XLT Series features refractor, reflector and Schmidt-Cassegrain optical designs coupled with the new Omni CG-4 heavy-duty German Equatorial mount and sturdy tripod featuring 1.75" stainless steel legs and center tray for superior rigidity and vibration dampening.

Along with the stable platform of the CG-4 mount the Omni XLT series features high quality optics. Using aspheric shaping technology in conjunction with hand-figuring the optics the Omni XLT presents an image with virtually no spherical abberation. Celestron also added the famous StarBright XLT coating system to further enhance light transmission.

With superior optics and a stable platform the Omni XLT series is a great choice for astrophotography. Use the optional dual-axis motor drive (#93522) and polar axis finder (#94221) to track objects for long exposure photography.

Four aperatures are available in the Omni XLT series, 102mm 120mm 127mm and 150mm, all with Starbright XLT Coatings. Locate and identify thousands of celestial objects on your laptop or PC with "The Sky" Level 1 software included FREE with every Omni XLT model.

The series features a Tall finderscope mount for easier viewing through finderscope. Machined focus knobs for fine tuning focus. The CG-4 German Equatorial mount has a refined style and provides the stability you would expect from Celestron's CG mounts.

TELESCOPE GOOD. Adorama...ehh

By

from Providence, RI  -  Avid Adventurer

Well, first off the actual telescope itself is very nice. You can see quite clearly with it. It is very cold where I am located right now so I have only used it twice, and you can see TONS litterally TONS of crater on the moon. I also took a look at Venus, which really isn't that special because our atmosphere interferes with its atmosphere with heat vapors so you can't see too much detail, but still very bright and amazing. The mount itself on the scope is stable but the latitude adjustment is POOR. MADE IN CHINA, so that iron is too soft. The second time I used it the rear latitude screw became warped from the mere weight of the scope itself in order to raise the scope. I had to take the ENTIRE thing apart, and rethread for a 3/8 US standard T-bolt. But now it is working perfectly. I bought this scope from another company because I had called Adorama via telephone and asked them if the item was in stock. They told me they had several in stoke. So I placed the order online 20 minutes later. The very NEXT DAY, I received an e-mail that stated the scope was backordered and they had no idea when it would be coming in. So I immediately cancelled the order because I refuse to order something when a company can not get their story straight. ALL IN ALL. A GREAT SCOPE, the mount just justs a better latitude adjustment. DON'T LET THAT TURN YOU OFF! Maybe you will have better luck then me. After knowing all that I know about this event, I would still purchase the scope. GREAT SCOPE.

My Best Scope Yet

By

from Chicago  -  Casual/ Recreational

I received my new Omni XLT 120 refractor about 3:00 pm Friday, July 20th. I set it up to get familiar with this scopes features. [...] First was the size, wow this is a large scope. The tripod and the mount especially the mount are quite heavy. This makes for a really stable platform. Considering the weight once fully assembled, slewing the scope was effortless. Just balance the scope as described in the manual. Note to Celestron: The box with the tripod and the box with the OTA both had manuals and software. The only problem I have to report is that I had to take apart the 1.25" star diagonal as the mirror was not positioned correctly. Two minutes to fix, no big. Also want to mention that the fine tuning knobs are so close together laterally on the mount and so large that they come into contact with each other. I will be getting flexible extender cables though for ease of reach, so again, no big. That night (last night) I took the new Omni out to the dark site ( two hours west of Chicago, Light pollution capital of the world ) to meet several astronomy club members and go for a test viewing. Another WOW! Everybody was impressed by the handling and optics. I have never seen the quarter moon so sharp and clear. Craters inside craters. The patterns of Jupiter were quite clear, after putting the light reduction cap on the lens though, as the light transmission is so strong. I was using eyepieces that are just to much for my 10" Dob; 5mm or 9mm on a 2X barlow. 25mm and 38mm really were the best for seeing open clusters. Even managed to spot that comet between Alkaid and Izar. This was my fifth or sixth viewing session with these new friends of mine and I saw more last night than all other nights put together. The Equatorial mount takes some study, but even so, try just looking for faint "fuzzies" through the finder scope and you might find M6, the "butterfly cluster," like I did. All in all an awesome scope for the price with great potential. I already have a wish list started.

Questions about this item:

Donna C  What do I need to hook up a Nikon D7000 to this telescope and photograph what I see?
WILLIAM N  You will need a t-adapter http://www.adorama.com/CNTA1Q.html and a t-mount http://www.adorama.com/MDNTM.html That scopes is not truly useful for astro photography. You could take some basic photos of the moon. If you buy a motor drive, such as http://www.adorama.com/CNMD4D.html you might be able to take images of brighter deep sky objects.
Shopper  i have a celestron omni xlt 120 refractor. I also have a Nikon J1 digital camera. what do i need to attach this cameral to the telescope for prime focus photography? Is this even possible?
Andrew R  At the very least you would need (in addition to the telescope) a camera adapter (like: http://www.adorama.com/BS780104.html ) and the appropriate t-mount for your camera ( http://www.adorama.com/LNTMNK1.html ).
BC C  For this scope, where is it actually manufactured? Components & lenses, and assembly? Thanks.
JOSEPH L M  I have had the 'scope for about 6 months, and it is fine, very fine. I am pleased with the mechanical parts and with the optical performance as well. I am an optics and astronomy professional, and have been very stringent in my tests of the telescope after receiving it at home. It is yet an inexpensive telescope, but since such testing is part of my bread and butter in my research work, I carried out all that I know how to do in testing this amateur telescope. I will not part with it. It is fun and easy and very reliable. I believe I have gotten a bargain... but please don't tell the company this. ;-) I am sure that the design specifications were very well adhered to or exceeded at the place of manufacture, which, for all components, appears to be China. I think that final testing and final integration and quality control is done Stateside, in California. Please check me on this if you wish. I cannot be more pleased with the 'scope, and I recommend it very highly. Best wishes for your purchase, Clear Skies, and good Observing! --JM / Tucson, Arizona / Sonoran Desert/ USA
