Lacerta
« on: 01:13:32, 12 July, 2018 »
You can find this interesting accessory here:

Pic below.

But I wonder if it would be possible to reverse the mounting to look a bit like my hacked about version in the second pic.  Then it would accommodate long refractors and catadioptrics with cameras mounted at the rear.

Anybody got one or seen one?

Cheers,

Peter

Only issue I can see is the alt adjustment would need re-engineering (bodging). The other advantage of such a pier arrangement is not needing to flip.

How do you polar align this setup?

Even before I did my lash up photo I realised that by rotating the RA axis 180 degrees that would put the scope on top of the mount so possible to have longer tubes.  But thought perhaps that would unbalance the system.  Also of course polar alignment would be impossible with the access point under the framework. Not that easy to get your eye to the polar scope in the original arrangement, although a while ago I made an adapter to use a web cam on the polar scope - worked quite well and saved the usual neck ache  ;)

But to be certain I contacted Teleskop service, and this is their reply:

'Dear Mr. Vasey,
thank you for your email. Yes this is no problem; you just have to turn the mount's R.A. axis by 180°.
Best regards,
Ruediger Maass'

I suppose one can think of it as a robust single arm fork mount.

Cheers,

Peter.
