Celestron Advanced VX 6 Inch Refractor Telescope

SKU: 22020

For planetary imaging and brighter deep-sky objects, there’s no better choice than a refractor. Unlike Schmidt-Cassegrain or Newtonian telescopes that have a secondary mirror, refractors offer no obstruction of the aperture, giving you the highest possible contrast. This refractor setup features an f/8 objective lens, which can be paired with one of our Nightscape CCD cameras to image brighter deep-sky objects or our NexImage 5 Solar System Imager to create dazzling images of the planets.

ABOUT THE MOUNT

The new Advanced VX mount was designed to provide optimum imaging performance for smaller telescopes. Now the smaller telescope can take advantage of All-Star Polar Alignment and autoguider support. Able to track through long exposures using permanently programmable periodic error correction. Image across the meridian without doing a meridian flip, so you can seamlessly image the best part of night sky. Advanced VX features significantly larger base castings than our previous design, improving stability under heavier loads. Improved motors offer more torque and can handle slight load imbalances with ease.

All-Star Polar Alignment Technology
German Equatorial Mounts (GEM) have long since been recognized as the mount of choice for astrophotography. Needing to track in only one axis for long exposures; adjustable counterweights and tube position for perfect balance, the GEM has few short comings when it comes to imaging. In order to do long-exposure astro-imaging, an equatorially aligned telescope is needed to allow your telescope to properly track the motion of the sky. However accurate tracking still depends on an accurate polar alignment. Even with a visible star very near the North Celestial Pole (NCP), the true celestial pole can be a very elusive place to find without assistance.

Now select Celestron mounts can utilize a new innovative Polar alignment procedure called All-Star™. All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment.

Here's how it works.

Once the telescope is aligned with two bright star, All-Star allows you to choose any bright star listed in the NexStar hand control to assist in accurately aligning your telescope's mount with the North Celestial Pole. Using the telescope's Sync function, the mount is able to point and center a bright star with a high degree of accuracy. Once centered, the mount will point the telescope to the exact position that the star should be if the mount were precisely polar aligned. By simply adjusting the mounts altitude and azimuth controls to re-center the star in the center of the eyepiece, you are actually moving the mounts polar axis to the exact position of the North Celestial Pole.

FAQ's

Can I use Polaris to polar align my telescope?
Since Polaris is very close to the NCP and not very bright, it is actually not a recommended star for the "All-Star" method. The advantages of being able to use stars other than Polaris are two fold:

Polaris isn't always visible. Not only can you use a variety of other stars but they are also brighter and more prominent.
The star you choose will be farther away from the NCP, allowing for greater accuracy when centering the star in the eyepiece.

Which stars are best to use for polar aligning?
For best results choose a bright alignment star that is near the Meridian, preferably close to the celestial equator. Try to avoid stars that are close to the west/east horizon or directly overhead because they can be more difficult to center using the mount's altitude and azimuth controls. Also stars too near the celestial pole are less accurate than those further away.
