I received the unit and automatically fell in love with the materials and built. I knew that this unit would take a beating from traveling to location setup/breakdown.  I have taken it with me out of state and traveled on airlines with no issues.  The tracking is superb. Nothing beats it.   Though online has mentioned so units needing some collimating on the polar scope, mine has been perfect for the most part.  I could do more collimating but to be honest I don't have the time to fiddle with it.  I've used my 350mm lenses on it = 560mm focal length on Canon T6I body and gotten the time indicated on it without an external auto guider.  (3 mins at times) 

It is costly and the most expensive for portrable trackers out in market. But I'm happy with its intended use.  To TRAVEL and go on location with minutes or setup time. 

Best Compact/Portable Astro Tracker in Market

As they say you get what you pay for. Astrotrac is the gold standard for trackers outside of full fledged equatorial mounts.

Gold standard for tracking devices

I have used AT for years, taking it to high mountain sites when I travel, and to desert star parties. I use the T-3100 wedge; it is  super-accurate and convenient for polar aligning, and nicely machined. I have a portfolio of fabulous star clouds with this AT. To test accuracy, I used a 300mm telephoto with a CCD camera/5 min exposures in Sagittarius (with the TH3010 mount/head + counterweight)and no guiding. Pin-point stars! As with any equatorial set-up, take the time to calibrate & polar-align. It is a snap, once you get the hang of it. It is also fun for the hobbyist to do some add-ons and improvements (e.g., a quick release plate, mounting hardware, etc.) The AT forum is excellent. The tips it gave are now second nature for me in using this device reliably.

Wonderful device!

I wish Adorama had carried the wedge made by Astrotrac. I had to order this from a telescope company in California. If you buy the Astrotrac the wedge is a necessary piece of equipment. The wedge makes alignment much easier.

Very good and well engineered

The Polar Alignment Scope MUST be properly aligned before using. It is not preset. It is not difficult to do, just time consuming. The PAS also falls out of the holder. This, too, can be remedied with a gasket. For the price of the Astrotrac, these 2 items should be standard.
Now the good stuff...I use a Canon T3i and have no problem getting 3 to 4 minute exposures with a 180mm Nikon AI ED lens. Setup is a breeze. I use a Manfrotto 701 head and a 496 Ball Head for the camera on top of a Bogen 3001 Tripod. I have even used a Sirui Travel tripod (~3#)on windless nights  with spectacular results. This is not only a great travel setup, I have been using this in the driveway instead of dragging out and setting up the EQ mount.

Overly pleased....

The concept behind AstroTrac is quite good, but the implementation is weak. It it very portable and has a great potential, however the documentation is out of date and does not correspond with the polar scope reticle, making it difficult to figure out how to properly fine tune the alignment. There appears to be no support for the unit since emails to the support site remain unanswered. A great idea and very portable, but overpriced given the outdated and inadequate documentation and non-existent support by the manufacturer. Expect a fair amount of frustration if you plan on any long-duration exposures and need to perform accurate polar alignment.

Excellent concept but poor support

After purchase, my heavy duty tripod, DSLR digital camera, and the Astrotrac became good friends. I have dealt with heavy and cumbersome tracking mounts taking 20 minutes to an hour on setup. This setup requires less than 10 minutes from attaching to the tripod and having a camera ready for astrophotography. For the price, its well constructed, lite, and very easy to use, and comes with very adequate instructions on setup.
It's worth the investment.

Good tracking for astronomy

This motor drive for astronomy is superb for travel.  I used it on Easter Island for the July 2010 solar eclipse.  It is lightweight and VERY accurate.

Superb instrument

The astrotrac works as advertised. The add on package Adorama put together is poorly thought out. The only way I could get the 12v cord to reach the astrotrac was to being the astrtrac up to the car window. It's 4 ft long; needs to be about 15 ft at a *minimum*
