Maksutov's 1944 design was the first-published meniscus telescope design, and was published in the widely-read Journal of the Optical Society of America. [11] [12] [7] This led to professional and amateur designers almost immediately experimenting with variations, including Newtonian, Cassegrain, and wide-field camera designs.
An alignment suitable for visual observation and short exposure imaging (up to a few minutes) can be achieved with a polar scope. This is a low-magnification telescope mounted co-axially with the mount (and adjusted to maximize the accuracy of this alignment).
Siril is a software application for astrophotography, which allows pre-processing and processing of images from any type of camera (CCD, planetary camera, webcam etc.). The images must be converted to 32-bit FITS format which is the format used natively by Siril.
Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon ) was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography.
During its first phase of operations, 2000–2005, the SDSS imaged more than 8,000 square degrees of the sky in five optical bandpasses, and it obtained spectra of galaxies and quasars selected from 5,700 square degrees of that imaging. It also obtained repeated imaging (roughly 30 scans) of a 300 square-degree stripe in the southern Galactic cap.
These were switched for the Wide Field and Planetary Camera 2 by the servicing mission STS-61 in December 1993. [1]: 343 WFC3 was originally conceived as an optical channel only; the near infrared channel was added later. WFC3 is intended to ensure that Hubble retains a powerful imaging capability through to the end of its lifetime.
Long Range Reconnaissance Imager (LORRI) is a telescope aboard the New Horizons spacecraft for imaging. [1] LORRI has been used to image Jupiter, its moons, Pluto and its moons, and Arrokoth since its launch in 2006. [2] [3] LORRI is a reflecting telescope of Ritchey-Chrétien design, and it has a main mirror diameter of 208 mm (8.2 inches) across.
Drizzle (or DRIZZLE) is a digital image processing method for the linear reconstruction of undersampled images. The method is normally used for the combination of astronomical images and was originally developed for the Hubble Deep Field observations made by the Hubble Space Telescope.
