Product Description

CELESTRON - Advanced VX 6" Newtonian Telescope (32054-OTA)

The Celestron Advanced VX 6" Newtonian Telescope Optical Tube is excellent for basic deep sky observing as well as planetary viewing due to the impressive light gathering power of the Newtonian Optical Design and Fast Focal Ratio. With the parabolic primary mirror, aberration is limited which helps create high definition views. With the fast focal ratio of f/5, wide screen views through this 6" Newtonian are especially impressive when observing brighter deep sky objects like the Orion Nebula (M42), Hercules Cluster (M13), and Andromeda Galaxy (M31).  For those new to astronomy and astroimaging, the Advanced VX 6” Newtonian is an excellent entry-level scope that can grow with you. The Newtonian optical design is simple to set up, and gives amateur astronomers the largest aperture for the price.

 The reflector optical design, like other catadioptrics, utilizes a system of lenses and mirrors to produce long focal lengths with a more compact tube length than refractors. This 6" reflecting optical tube features a 750mm focal length using a tube less than 2.5 ft long. In addition to the relatively compact design, reflector optical tubes are also lightweight for their size. An aluminum optical housing not only minimizes flexure and helps equalize the temperature inside the tube, it also reduces excess weight, making this 6" tube only 10 lbs.  

 Celestron's Newtonian Reflector corrects some of the optical distortions common to all catadioptrics, including chromatic and spherical aberrations that become more pronounced at higher magnification. By using a parabolic primary mirror, this optical tube can transmit sharper and more color faithful images than standard reflector telescopes, improving image quality for both observation and astrophotography. The resulting images are sharper along the edge of the transmitted field of view and have reduced color fringing artifacts.

I have been able to capture amazing images with such an inexpensive telescope. The relatively fast focal ratio allows for shorter exposure times and nice wide field images when paired with a larger frame ccd or slr camera. This telescope is a great tool for the price. There are of course things like the focuser that are what you would expect from such an inexpensive telescope but i am very happy to take this ota to and star party and i know it will perform, and if i feel like imaging i can do that as well.

I have had this ota for a few months now and i would recommend it to anyone looking to get into astronomy or astrophotography and is on a budget. (Posted on 7/19/2015)

I have a canon Rebel that I put on it the first night i took it out and the images are amazing .
at F/5 there is nothing out there that is nicer . (Posted on 7/9/2015)
