Amateur telescope making is the activity of building telescopes as a hobby, as opposed to being a paid professional. Amateur telescope makers (sometimes called ATMs) build their instruments for personal enjoyment of a technical challenge, as a way to obtain an inexpensive or personally customized telescope, or as a research tool in the field of ...
A telescope on an alt-azimuth GoTo mount. Note the keypad, resting on the platform between the tripod's legs, that is the telescope's hand control. Batteries are stored in the circular compartment just above the tripod. In this picture, the compartment is just above the hand control.
Hartmann screen used for the 200-inch (5.1 m) Hale Telescope Using a Hartmann mask to adjust focus Hartmann mask is a tool to help focusing telescopes , mainly used by amateur astronomers. It is named after the German astronomer Johannes Franz Hartmann (1865–1936), who developed it around 1900.
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.
These H-alpha filters are much narrower than those use for night H-alpha observing (see Nebular filters below), passing only 0.05 nm (0.5 angstrom) for one common model, [5] compared with 3 nm-12 nm or more for night filters. Due to the narrow bandpass and temperature shifts often telescopes like that are tunable within about a ±0.05 nm.
mBlock 3 is a block-based programming software based on Scratch 2.0. It interacts with Makeblock controller boards and other Arduino-based hardware, allowing users to create interactive hardware applications. The block-based code can be converted to Arduino C and supports various operating systems including macOS, Windows, Linux, and Chromebook ...
There are three main types of telescopes used in visible-light astronomy: Refracting telescopes, which use lenses to form the image. Commonly used by amateur astronomers, especially for viewing brighter objects such as the Moon, and planets, due to lower cost and ease of usage. Reflecting telescopes, which use mirrors to form the image ...
The simulated SSR was created to support making a software test version of the JWST, to help validate and test the flight software for the telescope. In other words, rather than using an actual test hardware version of the SSR, there is a software program that simulates how the SSR works, which runs on another piece of hardware. [29]
