I have been working with telescopes and wood for over 50 years.
I've spent the last ten refining the "New Classic 8" into an elegant, high quality, easy-to-use astronomical telescope with professional grade optics in a smoothly operating, rock steady mount.
Every feature reflects and reinforces another in this form follows function beauty. Everything about the mount contributes to holding the tube and its optics rock steady, in a flexible, smooth operating, system
Wood is used because it is an ideal materiel, not only beautiful, but well suited to telescope construction.
The high tech, many layered, Baltic Birch Plywood has a tight swirly grain similar to the Maple handles, and is stiffer than the same weight of steel. This holds the optics stiffly in place while dampening the tiny vibrations that telescope optics would otherwise magnify into the shaky sight that destroys the view through so many amateur Department Store type scopes.
Even so, the main advantage of wood may be it's thermal characteristics that almost eliminate the air currents caused by the nighttime cooling down of many telescope tubes. These air currents, like vibrations, are magnified and can ruin the view in poorly thought out scopes.
Bigger is better in the world of telescope optics because the whole idea is to collect as much light as possible. The eight inch diameter magnifying mirror is considered by many to be ideal for a personal use telescope. It's big enough to give you a lifetime of things to look at without being heavy and hard to handle, and without being so large as to catch and magnify every atmospheric wind gust between you and the sky.
Stars are so far away that high powers don't make the stars any bigger no matter how big the scope is. It's much better to use the wide field that low powers give to see the awsome sweep of star clusters, galaxies and nebulae.
There are three main non-optical parts to this telescope.
The 12 sided Dodecatube™ is an original design consisting of 12 flat slats set into 12 narrow ribs in such a reinforcing way as to create a very stiff and lightweight tube.
It's twelve sides function like a round tube while echoing the 12 signs of the Zodiac. Each angle is 15 degrees, which matches the 24 (include the ribs) time zones of Earth, each 15 degrees wide.
The reinforcing rib structure also eliminates the need for turbulence causing interior reinforcements and provides a nice handling exterior surface for pushing it into viewing position.
The clean, wide interior allows for smooth air flow to prevent wind currents in the optical path while allowing the mirror to cool to ambient temperature without electric fans.
The slats and ribs are each cut from one piece of wood to so the grain is matched all around giving it a strong unified look.
THE ROTATING BASE
Two vertical boards rise up from the rotating base to form supports for the two huge altitude bearing circles on either side of the main telescope tube.
The risers are reinforced on the outside of the tube swing path with long narrow buttresses, connected by an integrated eyepiece holder that double as carrying handles.
This reinforcement guarantees a stiff telescope support system that allows the telescope tube to freely rotate all the way through the mount, making it much easier to follow a star that is nearly overhead while giving the scope it's lithe animal look.
The COMPTON CLAMP™ and CRADLE ASSEMBLY
I actually had a true 'Eureka!' moment one day, after several years of testing and trying to come up with a good adjustable telescope clamp. I was working on a jig to make the tube when I had the common difficulty of pulling some washers off of a bolt. At one angle they slide right off, but if slightly askew, they lock up on the bolt. Eureka!.
Picture the telescope tube as the bolt, and our specially shaped clamp rings as washers. It took some refinement but the patented clamp now loosens and securely locks down on the tube with a simple one hand adjustment of that large wooden screw on the top. This allows easy back and forth adjustment of the tube for perfect balance, as well as tube rotation to place the eyepiece at a good personalized position for convenient viewing.
The sides of the mount do double duty as large circular altitude bearings which ride their laminate surfaces on pure Teflon pads. They are connected by three Maple connecting rods. The top rod has been enlarged to do double duty as a carrying handle, while the bottom two support the tube while balancing, until tightening the clamp gently lifts it to its suspended position.
The size of all Teflon / Formica bearing surfaces are carefully matched to the weight they bear, so that force applied to the tube smoothly translates into up-and-down and back-and-forth movement.
Whenever there was a flexibility in dimensions I tried to match the "Golden Ratio" of Fibonacci's number that naturally appears in an astonishing variety of natural phenomena - such as plant leaf placement.
The scope for sale is the one without the three holes in the large circular altitude bearings on each side of the tube.
