Product information

Celestron 120mm f/8.33 Omni XLT Refractor OTA ONLY, with 25mm eyepiece and star diagonal.

Equivalent to the Skywatcher Evostar 120 (which is out of stock in the UK available sometime in June 2020)

Attach this Celestron Refractor OTA to your choice of alt-azimuth or equatorial mount, and youll have a superb telescope for exploring the Solar System or delving into deep space. With almost 5 of aperture that gathers almost 300X that of the human eye, youll be able to see faint details with the Celestron Omni XLT 120. Check out the Andromeda Galaxy, the wispy structure of the Orion Nebula, or the Great Red Spot on Jupiter! The Moon will simply blow you away, and the rings of Saturn will be a sight youll never forget!

If you choose to mount this Celestron Refractor OTA on a simple alt-azimuth mount, and add an erect-image diagonal, youll have a very powerful terrestrial scope that can also be used for night-time viewing. For those with a view, the Celestron Omni XLT 120 will provide stunning images of wildlife, ships at sea, or other interesting daytime subjects. If you add a safe, properly sized solar filter (contact us for options) to the front of your scope, you can observe sunspots and safely watch solar eclipses! This telescope is truly a flexible instrument. Performance with the Altair Imaging - Ready Solar Wedge and Daystar Quark is very good - contact us for more information and ERF filtering options.

The Celestron Omni XLT 120 Refractor OTA sports quality optics that are fully coated with Celestron's famous StarLight XLT coatings. These optical coatings are used on Celestron's observatory-grade telescopes as well and will help ensure crisp views and maximum light transmission on your Omni 120.

The smooth, easily adjustable 2" rack and pinion focuser on the Celestron Omni XLT 120 accepts both 2" and 1.25" accessories. The telescope includes a 1.25" star diagonal and a 25 mm eyepiece that will provide 40X magnification in a 50-degree field of view. We recommend you obtain a few more eyepieces such as the Altair Ultraflat 18mm to provide a choice of magnifications when viewing celestial objects.

You can find those objects more easily with the included 6x30 optical finder-scope. As its name suggests, this monocular-styled finder provides a low power, 6X magnification to easily locate and centre objects in your eyepiece.

The included tube rings come with a Vixen-style dovetail, which will allow you to easily mount the Celestron Refractor OTA refractor on a wide variety of mounts. If you have a mount that youre not sure of, feel free to contact us to help.
