For its time it was a formidable project as the largest Schmidt camera
operating at F/1 ill then was only 200 mm in diameter and had a single corrector element.
Dr Arditti explained that the HyperStar system was a means of reconfiguring widely available Schmidt-Cassegrain telescopes (SCTs), which typically had focal ratios of around f/10, into Schmidt camera
configurations with much faster focal ratios of around f/2.
As it has a narrow field of view and other limitations, Spaceguard became involved in the DRAX project to install and operate a 24" Schmidt camera
which will conduct a wide-field sky survey to detect NEOs and other transient phenomena.
On May 14, 2004, from the grounds of Three College Observatory near Snow Camp, North Carolina, Johnny Horne used his 8-inch Schmidt camera
to shoot four consecutive images (on ISO 400 .lm) of Comet NEAT beside the Beehive star cluster (M44).
The same 48-inch Schmidt camera
that did the previous survey will do this one.
"The Schmidt camera
is not the first example of the combination of a mirror and a refracting component.
The project soon ran into technical difficulties, partly because the astronomers wanted to build two telescopes in one--a Schmidt camera
for wide-angle photography, which could be converted into a conventional Cassegrain reflector for spectroscopy when the giant corrector plate was removed.
In 1979 Bo Reipurth of the Copenhagen University Observatory noticed it on plates from a Schmidt camera
Hase at the Crimean Astrophysical Observatory at Simeis in the former USSR using a 25-inch (635mm) Schmidt camera
, it was numbered 147 in their list.
The 0.95 metre aperture wide-field Schmidt camera
was launched on a Delta II rocket into an Earth-trailing solar orbit 1,530km behind the Earth, where it will have an uninterrupted view of a 105 square degree section of sky in Cygnus and Lyra (see front cover image).
At long last, Celestron rolls out the true successor to its legendary Schmidt camera
series from the 1980s, and at an attractive price to boot.
Lower of San Diego, California, with a Schmidt camera
of his own construction.
