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 |
Build
Your Own Telescope |
Building your own telescope is a lot of fun and you often wind up with something better than you can buy without spending a lot of money. Over the years I have developed several building projects. They are presented here so you can build a great telescope with high-quality optics. |

New
and interesting work by Super
deep sky images from France And
more stunners from the Canaries |
In Bonn, Germany, Jan
Fremerey has built a 10" f/5 prime-focus telescope that is taking
amazing images of Jupiter. The prime-focus design is rarely used yet it is
a natural for imaging. Here
is his web site, a picture
of the telescope
and here
is an animation of Jupiter and Io. All that from one of my 10"
mirrors. 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 6888 M101, M81 and M1 (read his comments about zero image shift with a conical). And this new marvel of astro-imaging, NGC 891 Mischa Schirmer is a professional astronomer with his own personal set-up on Roche de los Muchachos, La Palma. The pics marked Newt are with my 12.5" conical and Keller corrector. |
We make Off-axis, Unobstructed Optical Collimators and Beam Expanders |
Off-axis, unobstructed optical collimators and Beam Expanders for science and industry are now available, and, due to our unique design and manufacturing techniques, they can be made larger and offered at prices considerably below those customarily encountered. Read More |

Optical products for science and industry | On-axis
parabolic, ellipsoidal and hyperbolic mirrors routinely down to f/3
Off-axis parabolic, ellipsoidal and hyperbolic mirrors. ConVex aspheric surfaces, both on and off-axis Single and multiple element refractive systems. Larger high-accuracy flats of varying shapes. Interferometric analysis. Custom design work and design assistance. |
High quality optics for professional and amateur astronomy | 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!
