Celestron Advanced VX overview

  • 1Description

Celestron paired a GoTo mount with a large-aperture OTA to produce this Advanced VX 6" 150mm f/8 Go-To Refractor Telescope. Pairing the fully motorized and computer-controlled mount with a refractor scope produces an observation platform optimized for astroimaging. Its optical tube features a 6" (150mm) aperture to draw in copious amounts of light — even light from distant deep space objects like binary stars, galaxies, and nebulae. Its moderately fast f/8 focal ratio allows for shorter exposure times than slower scopes, which means more images can be captured for later stacking in post. A large-drawtube 2" focuser allows the use of larger wide-field eyepieces or large imaging sensor cameras to be used without vignetting, and an included reducer adapter lets users install smaller 1.25" accessories like the included eyepiece or diagonal.

The OTA attaches to the motorized equatorial mount. Outfitted with dual-axis low-cog DC servo motors and digital encoders, the mount head moves and tracks objects with high-precision and almost no vibrations to ensure clear views. Its wide 7 - 77° latitude range and head design allows it to track low in the sky if it's set up on a hill or deck, and will clear the motors to avoid having to perform a meridian flip during long observation or imaging sessions. Guiding the mount is the NexStar+ computer hand controller. Packed with more than 40,000 objects, it has multiple alignment procedures to get users observing faster, with multiple automatic tracking rates to accurately follow fast-moving close objects like the Moon and planets and slower deep space celestial bodies. With features such as user-defined objects, customizable guided tours, and expanded info on over 500 objects in its database even novice users can quickly learn about the Universe.

    Celestron Advanced VX reviews

    Advanced VX 6" 150mm f/8 Go-To Refractor Telescope is rated 4.0 out of 5 by 4.
    Rated 4 out of 5 by from A fine scope Great scope! I had anticipated a little blue coloring on the achromat even at f 8 but there was nothing I could detect. Also I suspected the included 20 mm Plossl would not be the best but it's very good indeed. As for the GoTo mount it works well.I had to be wary of the OTA contacting the tripod legs in certain orientations. When this happens the drive stalls safely enough but then a re-alignment is required. When set up on the pole after 3 star alignment the instrument centered any object bang in the middle of the field every time. Otherwise I have found nothing to complain about and everything to praise about this scope.

    Rated 5 out of 5 by from A great package I have owned 4 scopes before this one. 4 much larger reflectors. I have to say, this scope outperforms all of them! After initial purchase I did have problems getting the mount to align (im in Southern hemisphere), and thought it was owing to the mount being new and a bug in the handcontroller software. Contacted Celestron and they replaced the mount head and handcontroller without any qualms. Since then, this thing aligns easily, and puts the object within the field of the 20mm eyepiece every time. I was a little wary of CA issues when I bought the scope, but I have to say the OTA has exceeded my expectations of an achromat. I have taken many planetary and deep sky photos with this scope, and the results have been very satisfying. An excellent product, with good support from Celestron.

    Rated 5 out of 5 by from A Spectacular Value Frankly at $, the Celestron 6 f/8 refractor on the AVX mount is really hard to beat. I owned a 6 apo f/12 years ago. I have been out of astronomy for 13 years and didn't know anything about this scope until my neighbor pointed the ad out to me. But the f/8 ratio REALLY concerned me with dire imaginings of blue blobs for stars or planets. After a month reading every review available, I decided to take the gamble and order it.Globulars like M13 or M5 can be easily resolved down to their core even with a 8mm or 6mm. Light gathering is on par with a 8 SCT, but the refractor's superior contrast and pin point stars make open and globular clusters, and touring the Milky Way, a memorable experience. It also passed the most severe binary star tests for 6 aperture.Unfortunately, seeing conditions never allowed me to exploit its full potential last Summer and Autumn with Jupiter or Saturn. The best nights gave me Cassini's division fully across the entire ring, and a discernible C ring from the black sky inside the ansae. One session gave me fleeting glimpses of Enke's Minima for about 10 minutes. Mars revealed its South Polar Cap, Syrtis Major, Sinus Meridiani, and other prominent markings with color filters even though Mars was not well aspected.The CA issue with this scope is a non-issue really. A Baader Fringe Killer and Moon & Sky Glow filters stacked or the Baader Contrast Booster (its a combined FK and M&SG filter) makes short work of any CA. Granted, what detail or contrast is lost by CA cannot be restored, but the CA in this scope is minimal and nearly non-existent unless you really look for it on certain objects and particular magnifications. Remember, I came from using a 6 f/12 oil-spaced Christen triplet, so I am hard to please when it comes to pin point focus, perfect color correction and high contrast detail. A poor tripod/mount is a real deal breaker for me, but the AVX mount is more than adequate to handle this scope. Damp time is about 1-2 seconds. Each component is easily managed for quick assembly. The OTA is 19 lbs, mount 16 lbs, tripod 18 lbs. Field weight 75 lbs with two counterweights. I am 64 with two strokes behind me and I can easily assemble it myself. A hardware store handle mounted on the tube cradle is highly recommended for safety and ease. I have transported it quite handily in a small Honda wagon.Admittedly, the focuser was not so hot, but after dismantling, re-adjusting the tube screws and adding a better grease, the image shift is gone and focusing is now smooth and quite satisfactory. It is trickier getting a good focus at f/8 then on my long focus Unitrons, and two-speed Orion Crayford focuser for $ would greatly improve things. Something nice to think about, but its a luxury now, not a necessity.Adding two extra cradle rings, a steel mounting plate, and a Telrad solved its front heavy nature by adding more weight at the focuser end. I can now comfortably sit in my astronomy chair and enjoy the view with a diagonal at any angle, including the zenith.If this wasn't already a great deal, lets throw in a very efficient goto system for good measure! The AVX mount gets me 10 arc minutes pointing accuracy using three alignment stars. A 32 or 20mm eyepiece more or less puts me dead on with every object across the sky.It is no f/12 apo, but it isn't 250 pounds and $ either. I doubt that I will ever see spokes or Terby's white spot on Saturn's rings like I did with the f/12 apo, but its one h*ll of a bargain at $! I have owned more than a dozen scopes from 3 to 13 in my 40 years of observing. This is one of the best toys I ever bought.Steve Franks

    Rated 2 out of 5 by from Disappointed The mount and tripod seem to be very high quality. I will have to return this item though because the OTA is really not what I expected from Celestron. The focusor is just plain sloppy, but the worst is there appears to be air bubbles IN the objective glass an dust and smudges on the back side of the objective. I am truely disappointed.
