AstroTrac mount and portable Pier

Package includes the following:

AstroTrac TT320X-AG
AstroTrac TW3100 Equatorial Wedge
AstroTrac TP3065 Pier and transport bag
AstroTrac 8xAA Battery Holder & Lead

The whole setup packs into a padded fabric protective cover, slides inside the pier, and fits in a neat cylindrical shoulder bag 150mm x 750 mm.

Much greater load capacity and tracking accuracy than Skywatcher, Ioptron and Polarie trackers. Can easily manage 5 minute exposures at 200mm when well aligned, or carry a small scope. Rides on a compact but extremely sturdy and precision made equatorial head.

Tracking rates: sidereal, solar, lunar
Drive accuracy: typically 5 arc seconds peak-to-peak over 5 mins
Exposure duration before reset: approx. 2 hours
Can be auto-guided in RA
Weight: Astrotrac head: 1.1 kg (7 kgs including pier and equatorial head) – Load capacity: 15 kg


I’m the second owner and have used it only lightly. Perfect working order. Example photo here https://pbase.com/rigel003/image/162332263

Note: the original polar scope was poor quality, hardly usable. I’ve replaced it with the superb Vixen Polarie polar scope (bought separately at $200), which fits in the polar scope arm of the AstroTrac. This will be included.

Original cost of whole setup over $2000. Asking $850 - includes postage in Australia
