Rotarion

Has anyone seen one of these up close or even in action?   Rotarion

Tempted to utilize something like this for a combined spectrograph/imaging setup as opposed to a multi scope operation.

Looks like a filter wheel on steroids. It's  a lot of weight to move about. It would be nice to have fixed ports with a rotating pick off mirror.

Yes but at 1/10 th the price.

Seems like having multiple co-mounted scopes with dedicated cameras would be less troublesome.

I think you are probably right. Means I can get exactly right equipment combo per application as opposed to a do it all single rig which might need to compromise somewhere

You'd need to be very confident in your focuser with the multiple setup. Like Louis D I think two scopes might be less fraught.

Hi all,

See below PRO research study for academia with single tube multi-application telescope solution (including spectroscopy), only with Rotarion.

In regards to the top image in this page, that is a light and portable telescope solution, and yes, TeleVue TV-85 focuser holds the weight.

In both examples, single multi-application telescopes reduces weight (no need of heavier mount), gear (second or third OTA plus focusers, etc..), and therefore saves money compared to multi-tube telescopes.

And even better, no differential flexure problems typical of multi-tube scopes.

FYI soon available in First Light Optics UK.

Cheers,

A.
