Ultimate Newtonian Telescope 8" and 10' f/6

The Ultimate Newtonian
8" and 10" f/6 all aluminum construction
For equatorial mounting

What if the Newtonian looked as good as a modern refractor (had a real aluminum tube and real machined fittings), and didn't show stars with spikes, and didn't require constant adjustment, and didn't have tube currents, and you could easily rotate the eyepiece to a comfortable observing position? And not only that but you got perfect achromatism, instead of nearly perfect achromatism, and wonderful superlative images of the best quality. And an 8" telescope weighed 20 lbs and was 50" long, not 40 lbs and 75" long, and it was 1/3 to 1/5 the price of an equivalent aperture apochromat. What if things could be done to raise the reflector to the highest levels of performance and appearance? What if the Newtonian suddenly stopped being not quite as good as a refractor? Wouldn't that be something!

All telescopes include 60 mm StellarVue finder and dual rate Moonlight Focuser. Parallax clamping rings and mounting plates are not included.

These telescopes embody features such as a robust mirror mount that will retain collimation over long periods of time; fine thread, large diameter collimation screws; exhaust fan; easily removable end (cell) cap and curved vane spider with easily adjustable secondary mirror holder of my own design. Everything is easily and conveniently accessible. And once this telescope is collimated it pretty much stays that way - no constant re-adjustment when you go to observe. This scope is solid and stable. Rotating rings, end rings and back plate parts are made of machined aluminum. Tube is of aluminum and all attractively powder coated. Focuser is a 2" Moonlight with dual rate adjustment and finder to be a 60 mm erect image, right angle. Purchasers are recommended to use Parallax clamping rings as shown in the above pictures. Scope is also available as an f/8 as well.

One of the main features of this telescope is the rotating head that allows the user to easily and smoothly turn the eyepiece to a convenient observing position. How this design works and how the head is adjusted is explained here

This is the curved vane spider for the 8" model. There are four vanes but they are .032" thick, and, importantly, they are only 1/2" deep. Others make them very deep, 1" or more. This creates a thicker apparent vane for off-axis rays or if there is even a very slight misalignment. Also, this design, which I developed over five years ago, uses opposing curves to add strength to the structure.

This is a 10" spider prior to painting flat black. The 10" model uses .060" thickness vanes but there are only three of them so the total obstructed area is reduced.

Combined mirror, tip-tilt plate and back plate assembly prior to powder coating. Simplicity itself. No complex cell that surrounds the mirror and retards thermal stabilization. The uncoated back is now free and exposed to air. Reflective coated surfaces resist thermal transfer - heat reflects inward was well. You can also see how the conical cross-sectional shape of the mirror allows the rear fan to pull air around the mirror from the front. Stacked washers allow for easy coarse focal position adjustment. Belleville washers are located between the top washer and the tip-tilt plate. The use of Belleville washers and not coil springs form a far more stable structure, both longitudinally as well as laterally. Collimations screws are stainless steel fine thread for smooth and precise adjustment. In fact, all the screws in these telescopes are stainless steel. Back plate is easily removable from end of tube for cleaning and mirror easily comes off for re-aluminizing. Read here for more.

The goal is to produce the ultimate all around instrument, and by that I do not mean to imply that it is average or compromised in any sense. It is outstanding in every respect. As a lunar, planetary and double star scope it is unequalled for its aperture. The curved vane spider insures star images that look like real stars not Christmas card stars and deep sky images are crisp and clean. It is made as well as any refractor and delivers images as good. I'll guarantee it.
