Celestron G11 (made by Scott Losmandy, so equivalent to Losmandy G-11) – mount 2 of 2<\/strong><\/h2>\n\n\n\n

This second G-11 has been equipped with the “classical” DDS (Digital Drive System) from Losmandy – so tracking is available, and Autoguiding can be applied (but no Goto, if you want this I can recommend the rather inexpensive OnStep-solution – including new stepper-motors because the original ones don’t support hi-speed).<\/p>\n\n\n\n

It’s an impressive piece of gear: very sturdy, smooth tracking, and ready to go. Only add a tripod or pier (a polar finder is included…).<\/p>\n\n\n\n

We were thinking of 1.400 euro + shipping (but if you live in Belgium or closeby we can probably find a way to deliver it…). But we’re open to every (serious!) bid :-).<\/p>\n\n\n\n

The second Losmandy G-11 as sold (only the tripod and the polar finder are missing), so with the DDS-electronics, and one counterweight.<\/figcaption><\/figure>\n\n\n\n

The DDS (Digital Drive System) from Losmandy, very easy to use…<\/figcaption><\/figure>\n\n\n\n

Including the Handset….<\/figcaption><\/figure>\n\n\n\n
\"\"<\/a>
The mount had (external) encoders on both axes, but these are not used by the DDS-system – but you could use them if you switch to another drive, the FS2 (Koch) maybe?<\/figcaption><\/figure>\n\n\n\n

Periodic error (measured over 34 minutes) – each period of the worm-gear is 4 minutes. As you can see, the curve is rather smooth (so easily corrected by autoguiding) and the maximum errors are +\/- 7.<\/figcaption><\/figure>\n\n\n\n

The mount before we added the DDS and its stepper motors (the original DC-motors can be added, if needed).<\/figcaption><\/figure>\n\n\n\n
