  • Description

    The Celestron PowerSeeker 50AZ is a great entry level telescope for adults, teens, and children. The 50mm front objective lens gathers enough light to show you the Moon, Saturn, Jupiter, Mars, and several bright deep-sky objects as well as visitors to our solar system, such as comets. The Celestron PowerSeeker 50AZ is quick and easy to set up, and weighs under two pounds. An aluminum tripod puts the telescope at a comfortable height for most people, and an included 5x24 finderscope, once properly aligned, will help you find objects faster.

    See objects in low, medium and high magnifications with included eyepieces

    Unlike the fixed magnification of most binoculars or spotting scopes, this 50mm telescope can see objects at different magnifications by simply changing the eyepiece. The Celestron PowerSeeker 50AZ telescope comes with three eyepieces for low, medium, and high power views. Additionally, Celestron has included a 3X Barlow lens, allowing you to double the magnification of any like-sized eyepiece you use with it. So, instead of just one or two magnification choices, you will have a total of six. 

    Great for celestial and terrestrial views, day or nighttime

    The Celestron PowerSeeker 50AZ also makes a great terrestrial telescope. When used with the included erect image accessory, your views will be right-side up and left-to-right correct. Watch a deer as it meanders across a field, or keep track of a ship’s passage through a bay or on the open ocean. With the PowerSeeker 50AZ, you will enjoy both daytime and nighttime observing, and all for a price that won’t break the bank.

    Print out star charts for your observing time and location

    Another cool accessory that is included with the PowerSeeker 50AZ is a piece of software called TheSkyX - First Light Edition. This beginner’s software has a database of 10,000 astronomical objects and enhanced images of 75 of the most popular objects. What is really helpful, though, is the ability to print out a sky map for the date and time that you will be observing. This personal star chart will show you the way the stars and planets will look for your observing time, helping you to get oriented faster and make the best of the time you have at the eyepiece.
