Celestron 22150 overview

  • 1Description

Designed for both astronomical and terrestrial use, Celestron's Omni XLT AZ 102mm f/6.5 Refractor Telescope is an ideal instrument to introduce beginner viewers to astronomy by giving them a complete setup for viewing the Moon, planets, meteor showers, and bright, deep-sky objects. Its manual alt-azimuth mount has slip clutches and slow-motion controls on both axes for precise tracking. The mount's single fork-arm design enables the optical tube to be aimed at or near the zenith for astronomical use, and pointed downward past the horizon for terrestrial viewing on a deck, through a window, or from an observational platform.

A 90° erector prism is included that corrects the image orientation for use on land as a conventional spotting scope. A single 1.25" diameter barrel eyepiece is included that yields 26x power, and any 1.25" eyepiece and accessory will fit the sturdy rack-and-pinion focuser to add greater versatility to the scope. Its adjustable-height aluminum tripod provides a stable observation platform, and its maximum height of 49" allows for comfortable viewing by most users. An integrated dew-shield helps to prevent condensation on the objective lens, while blocking stray terrestrial peripheral light from interfering with celestial observations.

    Celestron 22150 reviews

    Omni XLT AZ 102mm f/6.5 Refractor Telescope is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Easy to use for all I am an experienced amateur astronomer and I wanted a grab and go telescope especially for a quick lookin the cold months. This scope is 4 inch refractor which would be the smallest aperture I would want. With the upright prism and a celestron sky chart objects are much easier to find. The findercope has a two degree circle and the eyepiece is also two degrees (26mm). Optics are great and with the coatings its almost as bright as my six inch Schmidt. I've seen m33 as a wisp of light in a dark country sky. The Pleiades is stunning with my 15mm wide angle. A 9mm (73x) for globular clusters and a 6mm (110x) for planets are a must. Azimuth slow motion controls make following objects easy.

    Rated 5 out of 5 by from Great first scope or lightweight grab n go What a great grab and go scope! Perfect for fast set up and viewing when you have a few minutes, and also for travel. The scope comes with a decent 25mm eyepiece, and a right angle correct image diagonal (which is what would be required for terrestrial viewing. The mount is super light, and can be made more stable by putting the eyepiece tray on the spreader. However I never do, and it still works. Slow motion controls are what sets this telescope apart from some other in this price range. The red dot (actaully it's a circle) also works well, except for having to get on my knees to use it sometimes. I can easily carry the scope and tripod out with one hand. I typically prefer wide field refractors. Using the 102 at got great views of the Pleiades and other clusters. M31 showed up very well in the orange skies in which I live. Another plus is that the scope accepts 2 diagonals and eyepieces. As you get higher in the sky, the focuser struggles some with the weight. I do agree with others that scope rings and dovetail would help with the balance. The included dovetail is very short. For planets and bright objects, I used a light yellow filter. This appeared to sharpen the stars. As a first scope, or as a grab and go to complement your other scopes, I don't think the 102 F6.5 will disappoint.
