Exploring the Celestron 114mm Telescopes
If you like to look at the stars at night then you know how important a good set of optics can be. Various manufacturers produce binoculars and telescopes used by casual observers and those who are into backyard astronomy. Celestron 114mm telescopes come in both reflector and refractor styles along with a variety of optical accessories that allow magnified views of celestial objects.What are the features of Celestron telescopes?
All 114mm telescopes use that size as their primary mirror. Each of these telescopes is a Newtonian reflector design. The 114mm products include different scope sizes, varying optical qualities, and so on. Some are also portable telescopes. Additonal characteristics include:
- Powerseeker 114EQ telescope - Focal Length 900mm, 5 x 24 Finderscope, German Equatorial Mount, Aluminum Tripod
- Explorascope 114AZ telescope - Focal Length 1000mm, StarPointer Red Dot Finderscope, Aluminum Tripod
- Cometron 114AZ telescope - Focal Length 450mm, StarPointer Red Dot Fidnerscope, Alt-Azimuth Mount, Adjustable Stainless Steel Tripod
- Astromaster 114EQ telescope - Focal Length 1000mm, Bullet-On StarPointer Finderscope, CG-2 Equatorial Mount, 1.25-inch Steel Tube Legged Tripod
The Barlow Lens is named after the English mathematician and physicist Peter Barlow, who created a forerunner of the lens in 1833. It is used on a telescope to increase the focal length as seen through the instruments optics. This magnifies the image being viewed in the eyepiece. Most Barlow Lenses that are used with telescopes double (x2) or triple (x3) the magnification. An adjustable product is also available that can vary between x2 and x3 power with the use of an extension tube.Are there computerized controllers for these telescopes?
Computer control on Alt-Azimuth mounts are available for the 60LCM, 80LCM, 114LCM, Astro Fi, CPC, and the Celestron NexStar series of scopes. Computerized German Equatorial mounts are available for the Advanced VX, CGEM II, CGX, and CGX-L series of instruments. Both of these mounts are also available from the company with manual control features only.Who makes filters for telescopes and why are they used?
Filters are used by observers to enhance the colors of planets and other objects. They can also be used to block out light pollution. There are a handful of companies that make individual or sets of these filters. Some companies also make a colored filter-wheel that can be placed on the end of a Newtonian-styled telescope. Orion produces filters that block out most of the suns light so that it can be observed safely.Content provided for informational purposes only. eBay is not affiliated with or endorsed by Celestron.
