I'm thinking this would make a fantastic combination observing chair and dual parallel mount setup for multiple instruments:
Just one catch: It is being sold by Correctional Services Canada, so it has likely been used in a federal prison.
I bet it would be comfortable!
I could see mounting some nice astro-binoculars to it. Also if the motor controls for the chair were operational that would be nice.
It reminds me of a scene in Lara Croft Tomb Raider. If you have seen the movie then you should remember the part where Lara Croft is looking through a telescope at the planets aligning. I always thought that it would be pretty cool to have a set up with a reclining chair mounted to a huge refractor like in the movie. I doubt it was a real telescope or even be possible to have a set up like that but it sure would be nice. It would make for some relaxing viewing sessions but that's about it.
If you haven't seen the movie just google Lara Croft, Tomb Raider "Telescope Scene" and you should be able to get an idea of what I'm talking about.
