Time to shift some gear.
For sale is Losmandy StarLapse Tracker in good condition. These units are no longer in production.
All the details you need can be found here:
http://www.losmandy.com/starlapse.html
Main advantage of this system is its carrying and balancing capacity without the use of counterweights.
Asking $550. Prefer local pickup in Sydney but will post at your cost.
PM me if interested.
Thanks.
Ted
