Schmidt Camera Strictly speaking, the 8-inch Schmidt camera from Celestron is not really a telescope at all. Instead, one mounts a small piece of 35mm film into a curved-surface magetic holder, and then attaches the film holder at the focal plane of the instrument through an access hatch.
Exposures begin the moment the observer removes the cover from the film chip.
In addition, their rugged lightweight construction makes them good choices for tripod mounting and transporting to dark sites for star-parties. Although the small aperture, 3.5 inches in diameter, only gathers half the light of the 5-inchers, the telescopes produce extremely crisp images at all magnifications.
