Product Description

Product Description

Orion Dobsonians have always been known for superb optical and mechanical quality, wonderful ease of use, and remarkably affordable prices. One other thing they - and almost all other Dobs on the market - have had in common: you pushed the telescope to your observing target by hand. Until now. Orion is pleased to herald another giant leap in Dobsonian evolution with the introduction of the SkyQuest XTg series of fully motor driven GoTo Dobsonians. Now, pointing a Dob to even the most elusive of NGC curiosities is as easy as pushing a button or two on the XTg Dobsonians' illuminated hand controller. High-torque servo motors guided by two pairs of high-resolution encoders then slew the telescope right to your object of interest - any of over 42,000 objects in the GoTo controller's database. No more nudging the telescope tube continuously to keep the object from drifting out of the field of view, either. The XTg automatically tracks the object's motion, keeping it centered in the eyepiece while you savor the view. What's more, the closed-loop electronics of the XTg let you move the telescope manually - or endure the accidental bump - without losing orientation for accurate, automated GoTo pointing!

(I am sorry that this is a bit long but with such an advanced instrument, more information will probably help out prospective buyers better.)

For years I have wanted to begin dabbling in viewing the heavens and amateur astronomy only to find that I was usually too busy to get around to researching the topic properly. With the potentially high cost of telescope equipment and fear of purchasing the wrong model, I continued on my track of ignorant inertia for many years. What finally spurned me to take action was my small five year old son announcing that he would like to look through a telescope and learn about, "the places where alien creepy crawlies probably live". (He is especially interested in the concept of exoentomology) Despite working as an academic, I really did not have any practical astronomical know how. I remember learning about the optics equations while taking physics in high school and university and a few problems from mechanics which occasionally touched on the subject of telescopes. I even knew a few constellations and bright star names. But, aside from that, I really could not have told you the difference between a refractor or a reflector.
What I did know was that I had a budget that the wife would not allow me to go over and I wanted to try and purchase the best equipment I could. Obviously, I consulted Google and began reading all manner of astronomy forums and product reviews, and quickly learned about Celestron, Meade, Orion, Zhumell and many other reputable brands. I also quickly realized that my primary interest was in viewing and not astrophotography. I then attended a star party here in San Jose, where several members recommended either a Dobsonian or a SCT design.

I ordered this scope right after Christmas 2012 and have only now gotten to use it. A friend has said he never saw anyone get a new telescope that didn't bring on multiple days of cloudy weather. This scope was recommended by that same friend and he didn't steer me wrong.

My first impression was how well this scope was packaged. I am a medical professional I we don't get instruments that are packed and protected as well as this. The base is packaged separately from the optical tube assembly and comes in several pieces. Assembly is not difficult, but having not done this before I worked slowly and carefully. I'm sure I could put one of these together now in no time at all.

The two eyepieces that come with it are adequate for familiarization with the scope but I ordered the 1.25 inch eyepiece accessory kit as well. The 1.25 eyepiece has illuminated cross hairs so it does double duty to help you center objects for initial calibration of the GoTo computer and works in tandem with the illuminated reflex finder scope to get you pointed in the right direction. Once you get it pointed at a reference star you are good to go. I've looked at a variety of object over a wide part of the sky and the goto mechanism never failed to precisely guide and track the object.

When I have consulted product support, both by email and by their live chat, they have been very helpful.

Since nothing is perfect some criticism is in order, but doesn't affect my 5 star rating for this scope. The main parts of this telescope seem to be sturdily built, but I question the sturdiness of some parts. The rack that can be used to hold your additional eyepieces is held on by some rather short screws that go into a wooden part of the base.

I recently bought my second Orion telescope. I was very impressed with the company until I got the GoTo Dobsonian. My review was not glowing so they deleted my comment.

The scope was more than I was expecting and I really don't have any serious complaints. After knowing what I know now, I would still buy it. It is far nicer than my previous 8" Dob. I am very glad to have the motorized version. Very nice to just look at things without having to re-align every little bit.

The quality of the scope is fine. Fairly rugged. Except...The small sighting device is junk, almost worthless and extremely disappointing. (that is what got my comment deleted on the Orion website.)

The GoTo function is not very user friendly and not at all reliable. I work and work to set it up and then all is well. It has taken me almost 1 hour to set it up a few times. I live in the forest and have to use different stars to set up the GoTo function. The only easy way to use it is memorize 75% of the stars in the sky. I take my laptop out with me to find the stars with the really great program that comes with the telescope. I pre-plan my viewing in the house.

Based on what is available in my time window, I can go out and see nebulas, galaxys, fantastic views of Jupiter and it's moons, and things I never saw with my non-motorized 8" Dob. Don't expect to see anything similar to what you can see on the internet. The galaxys are just bright spots that are fuzzy. The nebulas are black and white only. Jupiter is in color with my new scope.

I recommend buying the 2" barlow. I find I use it far more than higher power lenses that require the smaller diameter.
