A few years ago now I was down in my shed and I noticed a spare stubby holder on my work bench.
After a bit of thought I came up with the perfect use for the stubby holder, in an observing chair, but first I had to build the observing chair.
Attached are images of my chair in pieces ready to pack in the Land Cruiser to head off to the SPSP, two day drive and about 1,100 km away.
There are also two images of my chair assembled at the SPSP. This was, I think 2006, back when I was taller than my son. The steering wheel by Christopher's left hand spins a reduction gearbox that lays the chair back toward the horizontal. The chair is capable of anywhere between the angle that it is with Christopher and horizontal.
The steering wheel mounted in the vertical plane on Christopher's right hand side, spins another reduction gearbox that rotates the chair around it's central axis 360 degrees. The movement of both azimuth an altitude is quite fine. I mounted a 120mm Scanner refractor on the yoke that hinges down and locks in position in front of the person in the chair. The scope mount is highly adjustable, allowing the eyepiece to be positioned at a comfortable distance from the observers eye.
As the chair moves, regardless of the azimuth or altitude, the distance between the observers eye and the eyepiece is maintained. Obviously, with the observer positioned within the telescope mount, high magnification is out of the question, however with a 30mm wide field eyepiece at allows for an incredibly comfortable tour of the night sky.
On Christopher's left hand side is a file container that houses an A4 laminated set of star charts. On Christopher's right hand side is a shelf housing note pads, a star wheel and "The Stubby Holder".
The actual padding for the chair was put together by my wife Cheryl, created from cutting and joining six car seat, lower back supporting pads, from "The Reject Shop".
When I told Don Whitman about the quandary over, what to do with the spare stubby holder, he just shook his head.
One thing scares me about binocular chairs. If the binoculars slip, there is nowhere for your head to go but suffer squish on your eyes - Ouch! big time.
When I opened the images attached to your post, I initially thought the rig was one of those USAF or NASA tracking platforms that capture high speed footage of experimental airplanes and rockets!
If that's what your creativity and engineering produces when you spy a stubby holder, my mind boggles at what other creations you have around your place!
I knew those legs looked familiar!
Here is a film camera shot of your scope and my 8
in my backyard, circa late 80's I reckon.

That was a long time ago Steve, sure has been a lot of water under the bridge since then.
Those legs are now on the base for the trapezium mount that I hang my 15 x 70 binoc's on. The legs on the chair started life on the the mount that my 16" is currently on, before I shifted my observatory. They look similar but this set has 3mm wall thickness and are overall a lot sturdier.
It really is amazing the various astro bits & pieces that have accumulated down the shed.
I totally rebuilt my original 10" as a Dob to take to the SPSP years ago. Ended up swapping it for a 120mm refractor on, I think a Eq6 mount.

Top stuff!

Dennis, do you mean something like this ? They are trying to sell it for months with no success.
I think you need to be more than just bored to create that complex baby :-)
