Huge mirror lens 2540mm focal length, aperture F/8! These lenses were used by the NASA for tracking the Saturn V or similar. I was told by the grandson of its producer John H. Ransom, that the tragedy of. The Space Shuttle Challenger was tracked and filmed with Jonel lenses.They used high speed 70mm movie cameras like the Photosonics 70mm 10R with. Up to 125 fps on 6x6 frames (this camera is also for sale, seperate).
It is a Schmidt-Cassegrain design with a two element field corrector to produce a 57x57mm image format (80mm image diameter or more). Optics mint, barrel mint- (some loss of paint). The barrel is incorporating a system to avoid humidity inside, it is very rigid, and the design. Is very sophisticated, compared to modern Astro cameras.
I added a test shot : a blow up of a raw file (Canon EOS 600d), taken with the big. Brother of the Jonel 100, the Jonel 200 (5080mm F/16) at 600 feet distance.The diameter of the small. Star sector target was 40mm. Resolution is a little more than.
(50 line pairs per mm) with the Jonel 200 , and will be a bit more. Original costs (for NASA) : about one family home.
180 pounds in original case. Ask me for tripods, heads and for focusing units.
You may compare it with the actual lenses from Brashear (50"/ 100"/ 150). The way, ask them for their pricing. Astrograph Veloce RH 300 f/3 with just 60mm image circle. Of the Jonel is much more sophisticated. This isn't a bad price for range glass.At work, we have a handful of 100s and 50s as well as some 38 IR lenses that all cost over a 100k. They are built for long range optical triangulation and even small offset can add up to huge error at 100s if thousands of feet. Please also check the Carl Zeiss Mirotar 5,6/1000mm , designed for 56x56mm. (the sharpest non military Telelens for 6x6).
I wish I had a 8/2540mm Mirotar, but the cost would be more than 10 family homes. Combination (payload up to 380 pounds) and a focusing unit, carrying my Pentax 6x7.
