Track stars and other celestial objects easily
Astronomy Products – Tracking celestial objects as they travel across the night sky using guided wide-field astrophotography usually requires you set up a heavy telescope mount, even if you just need to support a lightweight camera and lens. The 2.2-pound (1 kg) AstroTrac TT320X-AG is small enough at just 17x3x1.5 inches to be easily folded and tucked into a camera bag. This mount unfolds quickly and reliably, and can be mounted on a camera tripod, and then aligned with the celestial pole using the optional polar scope, to track celestial objects across the night sky precisely. The AstroTrac TT320X-AG is compatible with both the AstroTrac Polar Scope, Pier, Wedge, and Head products and allows you to take longer exposures at extended focal lengths, for bright images with less noise. AstroTrac indicates that the TT320X-AG only has a tracking error of about 5 arcseconds, peak-to-peak, over a period of 5 minutes, perfect for wide-field views.

Astronomers need a good star tracking guide
The AstroTrac TT320X-AG uses 8 AA batteries to provide power for its systems, which provides about 10 hours of use, and AA batteries are pretty easy to pick up, so power usage shouldn’t be a problem. The AstroTrac TT320X-AG also has a right ascension auto guiding feature that’s compatible with popular brands of auto guides, like SBIG SG-4, Orion Starshoot, LVI SmartGuider, and auto guiding software like Maxim DL and Ph.D., but you’ll need to order an additional cable required separately, to use this feature.
