Celestron Advanced VX Mount - an affordable EQ mount that was engineered from the ground up with astro imaging in mind. 

The new Advanced VX mount was specifically designed to provide astro imaging performance for smaller telescopes. The Advanced VX Mount offers both All-Star Polar Alignment and autoguider support. You'll be 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.

Experienced imagers will love taking this portable mount to a dark sky site, with all the performance of their larger observatory mount. Or, if you're new to imaging, this mount will help you get started with the hobby and keep up with your needs for years to come.

What is polar alignment?
Polar alignment is the process of physically aligning the mount's primary axis of rotation, also known as the right ascension axis, with the Earth's own axis of rotation. Once this is achieved, the mount may track any celestial object it is pointed at by rotating the telescope on that axis at a rate of one revolution per day.
How is Polar alignment achieved?
Getting a rough polar alignment is pretty straightforward for those of us operating in the northern hemisphere, because the northern celestial pole is very close to Polaris, the north star. Sighting and centering Polaris through the bore of the right ascension axis is usually good enough for visual observing. The right ascension axis is perpendicular to the counterweight shaft.
How is precise polar alignment for astrophotogarphy achieved?
In the case of the Celestron Advanced VX mount, there are two choices. The NexStar computer system includes a utility that will walk you through the process after a rough polar alignment and go to alignment have been performed. The All Star polar alignment process instructs you to slew the telescope to a bright star some distance away from Polaris, then adjusts the aim based upon the assumption that the polar alignment was perfect. Then you physically adjust the mount in both latitude angle and azimuth until the star is centered. The alternative is to install an optional polar alignment scope in the bore of the right ascension axis. Once the polar alignment scope is properly calibrated, it will show you where to place Polaris for a near perfect polar alignment.
