celestron cgem-1100 computerized 11-inch cassegrain telescope


 


 


Product Description


celestron's CGEM-1100 telescope offers premium performance and mobility for stargazers seeking the ultimate Astronomy experience. It features an 11" Optical Tube weighing only 27.5 lbs., and a telescope mount with a unique ergonomic design for ease of use and convenient mobility. Equipped with StarBright XLT coatings it can capture up to 89% more light gathering power than an 8" telescope. The CGEM-800 Equatorial mount was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment. The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up. The CGEM series has a new innovative Polar alignment procedure called All-Star (patent pending). All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CGEM, sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will alow users to train out the worm gears periodic errors, while the mount retains the PEC recordings. For objects near the Meridian (imaginary line passing from North to South), the CGEM will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM mount has a robust database with over 40,000 objects, 400 user defined programmable obects and enhanced information on over 200 objects.

Customer Buzz

Celestron PowerSeeker 80EQ Telescope is a decent beginner's telescope as it has a German equatorial mount for some smooth tracking of heavenly objects, once you magnify a celestial object you will see that without an equatorial mount it becomes difficult to keep the object in focus if you do not have finer movement of the axes. The telescope does a fairly good job in tracking the objects in sky.



Having said that the telescope is better than a toy which one gets in a departmental store it stands true, Do not expect to see spectacular views that one gets via media and news, those pictures were taken using very high resolution telescopes or may be hubble telescope which we are so much accustomed to.



PROS:



(+) German Equatorial mount provides decent tracking of objects in sky

(+) Tripod mount is not too bad for the price range.

(+) Decent optics, only one useable Eye piece (20mm)

(+) Uses Standard eyepieces (1.25 inch)

(+) Digital Camera Attachment is possible for astrophotography if you buy the right accessories matching your Digital camera.



CONS:

(-) Does not magnify enough for you to see spectacular details one wishes for.

(-) Other than one eyepiece (20mm) all other eyepieces' are not useable making it difficult to use them in the telescope for better view of the celestial objects.

(-) When the Tripod is extended all the way out, it shakes and makes it unusable.



Having said, this is a decent Telescope for watching at the moon, but I could not see any better than what is visible to naked eye when it comes to other planets, I am not sure why the magnification is not good enough to see more details when it comes to planets.



If you can find this telescope for less than $80 dollars it is well worth it for occasional sky watching, never for any serious astronomy or astrophotography use.





Customer Buzz

A piece of real crap. Never even think of buying this.



After lot of difficulties, I could finally point it to the moon. I only saw white light through its eye-piece as much as I can see with my naked eyes!!! The eye piece is so small, it seems as if I poked a hole on a piece of paper and watched a portion of the moon through the paper. And I paid so much money to see that crap?



Then I focussed on a distant star. It just appeared as it would appear through a 4x cheap binocular.



Believe me, don't buy a telescope if you live in a city and have enough "noise" from other light sources. If you live in a country side, you'd better buy a better telescope and not this crap.



I finally sold it on ebay and bought a good pair of Nikon binocular. The moon looks awesome through the Nikon binoculars. Read my other review on Nikon binoculars.

celestron starhopper 12 telescope - 10112


 


 


Product Description


celestron is proud to introduce our StarHopper series of Dobsonian telescopes. Dobsonian telescopes are recognized within the astronomy hobby as an excellent value for the aperture size, and the celestron StarHopper line is as rich in features as it is in value. The Dobsonian configuration is a Newtonian optical tube mounted on an altazimuth mount. The optical system features a large primary mirror at the bottom of the tube which collects light and concentrates it onto a small secondary mirror, which reflects the light out the side of the tube and into the eyepiece. Best of all, StarHopper Dobsonians are easy to observe with -- the user navigates through the night sky by simply moving the tube up or down, and left or right, by hand. All StarHoppers use optical quality BK-7 glass, this is the same high-quality glass used in most binocular prisms and refractor telescope lenses. All StarHoppers use a roller track bearing on the azimuth surface providing dozens of support points for smooth swivel motion. They also use a variable tension clutch system for proper balance and control in both altitude and azimuth.
