Observatory Dome

Hi,

I remember seeing an observatory with an unusual shutter, but I don't
remember where. It was a hemispherical dome which rotated in azimuth,
business as usual. The shutter as a round hole, which was on a separate
sector of the sphere. This sector would rotate as well in order to
change the altitude of the hole. Has anybody seen this ? I have no idea
where I saw this, but it's kind of cool.

Thanks.

Eric.

Its quite a neat thing.

Hi,
Several years ago I saw a portable observatory, the "Sky Tent". It was made
from PVC (?) tubing and covered with fabric. It was a conventional dome type
and came in several sizes.
I believe the makers have gone out of busness.
Does anyone know if there are any plans, kits, or anything about this?
They were very nice and I can now afford one, but naturally I can't get one!
Thanks;
Ken

That's the idea. Looks like it does exactly the same thing.
Thanks, Steve.

I have seen it from the inside and its neat, in that one can observe
from a warm, or at least temperature controlled room !

The window also has to be tilted to get it parallel to the OTA too. The
geometry is NASTY !
