-
A.
Maksutov–Cassegrain telescope design
The Maksutov–Cassegrain telescope design is a compact catadioptric optical system that uses a spherical primary mirror and a meniscus corrector lens to provide long focal lengths with well-corrected, high-contrast images in a relatively short tube.
-
B.
Dall–Kirkham telescope design
The Dall–Kirkham telescope design is a type of reflecting telescope that uses an elliptical primary mirror and a spherical secondary mirror to provide good on-axis image quality with relatively simple, easy-to-manufacture optics.
-
C.
Schmidt–Cassegrain telescope design
The Schmidt–Cassegrain telescope design is a compact catadioptric optical system that combines a spherical primary mirror with a Schmidt corrector plate to provide long focal lengths in a short, portable tube widely used in amateur and professional astronomy.
-
D.
Schmidt telescope
A Schmidt telescope is a wide-field reflecting telescope design that uses a spherical primary mirror and a correcting lens to capture sharp images over a large area of the sky.
-
E.
Metis coronagraph
Metis coronagraph is a specialized telescope instrument designed to block the Sun’s bright disk so it can image and study the faint outer solar corona in visible and ultraviolet light.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
NEDg
Description generation
