The
Ultimate Newtonian |
Images
as good as any refractor.
With my complete system; conical mirror,
high-quality optics, curved vane
spider and fan ventilation; I guarantee performance like an apo but
at a fraction of the price. And you get real aperture. Last
summer I tested one out and was amazed at its performance. All parts
are made of machined aluminum and powder coated for durability and attractiveness.
Moonlight focuser and 50 mm right angle finder standard. And now
with a rotating head option or Parallax rotating rings.

Planetary
Dall-Kirkham OTAs |
These complete Dall-Kirkham OTAs are now available upon request. Optical design is optimized for no compromise, small obstruction, high-resolution lunar, planetary and double star visual or imaging use. No multi-lens optical train. 8" and 10" sizes are closed tube and 12.5" - 16" are open tube designs. Delivery time depends upon available stock and range from a few weeks to six or eight months. 14.5" and 16" sizes are designed and available. Read More | ||

In Development 11" f/4.1 Super Houghton Astrograph - Read More Pictures and progress reports to appear as the instrument develops |
Over the current year I will be building the prototype of an astrograph having an amazingly large, flat field. The corrected or super Houghton-Newtonian optical design is capable of producing a flat, diffraction limited (6 µm Airy disk encircled spots) image circle covering 3 degrees of sky. A 1" chip will cover 1.8 degrees of sky completely unvignetted with a 41% obstruction. OTA will feature a carbon fiber tube, Clement Bellerophon III focuser, exhaust fans, and (unlike parabolic mirror near-focal correctors) be comparatively insensitive to misalignment and thermal effects. Price for this model is anticipated to be in the $15,000 range. Other sizes and focal ratios down to f/2.78 and lower possible on special request. | ||

See what Vincent
Steinmetz, from Strasbourg, France has
done with one of my 8" f/4.5 conical mirrors and Keller and Baader MPCC
coma correctors.
He has built his own astrograph and here is NGC

Parabolic
mirrors for Newtonian telescopes.
Compound reflective optical systems including Cassegrain, Ritchey-Chretien, Dall-Kirkham and various modifications. Refractive systems including achromatic and apochromatic objectives and full aperture corrector catadioptric systems including Schmidt, Maksutov and Houghton types along with near focal corrector systems. Both standard full-thickness and conical cross-section mirrors for Newtonian and compound systems. Articles for the amateur about telescope design, construction and use. |
New product for both amateur astronomers and professionals.
The conical cross-section mirror has arrived for Newtonians. Light in weight but no compromise in wavefront accuracy. - And no flotation cell required. Mounting is simplicity itself. The first real advance in lightweight larger aperture Newtonian telescopes. Details inside!
