This feature allows users to affix up to 32 graphical sliders providing callbacks to default or user-supplied routines that perform evaluation or even full optimization iterations when a slider is moved. Some examples in the use of these slider wheels to design telescopes are provided by Howard. [9]

PLate OPtimizer, or PLOP is a CAD program used by amateur telescope makers to design primary mirror support cells for reflecting telescopes.It was developed by telescope maker David Lewis, first described in 1999, [1] and used to simplify calculations needed in the design of mirror support cells. [2]
Primary lens: The objective of a refracting telescope. Primary mirror: The objective of a reflecting telescope. Corrector plate: A full aperture negative lens placed before a primary mirror designed to correct the optical aberrations of the mirror. Schmidt corrector plate: An aspheric-shaped corrector plate used in the Schmidt telescope.
The primary mirror focuses the light and reflects it back up, where it exits the vacuum tube through six quartz optical windows in the floor of an optical laboratory at ground level. The telescope's entire optical system – from the top of the tower to the base of its underground portion, plus the 40-foot-diameter (12 m) observing room floor ...
Planetarium software is application software that allows a user to simulate the celestial sphere at any time of day, especially at night, on a computer.Such applications can be as rudimentary as displaying a star chart or sky map for a specific time and location, or as complex as rendering photorealistic views of the sky.
Cartes du Ciel ("CDC" and "SkyChart") is a free and open source planetarium program for Linux, macOS, and Windows. [2] With the change to version 3, Linux has been added as a target platform, licensing has changed from freeware to GPLv2 and the project moved to a new website.
The model can then be used in a telescope control system to correct the pointing and tracking. Such errors are typically caused by mechanical or structural defects . For example, TPoint can analyze and compensate for systematic errors such as polar misalignment , mechanical and optical non-orthogonality, lack of roundness in telescope mounting ...
