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.
Drizzling is commonly used by amateur astrophotographers, particularly for processing large amounts of planetary image data (typically several thousand frames), drizzling in astrophotography applications can also be used to recover higher resolution stills from terrestrial video recordings. [1]
Lucky image of M15 core. Lucky imaging (also called lucky exposures) is one form of speckle imaging used for astrophotography.Speckle imaging techniques use a high-speed camera with exposure times short enough (100 ms or less) so that the changes in the Earth's atmosphere during the exposure are minimal.
Monochrome astrophotography has gained its popularity as a method of combating the effects of modern light-pollution. The Bayer matrix in a traditional sensor will limit the available sensor area capable of collecting light from deep space objects to approximately 25%.
Afocal photography works with any system that can produce a virtual image of parallel light, for example telescopes and microscopes. Afocal photographic setups work because the imaging device's eyepiece produces collimated light and with the camera's lens focused at infinity, creating an afocal system with no net convergence or divergence in the light path between the two devices.

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.
Astrometric solving or Plate solving or Astrometric calibration of an astronomical image is a technique used in astronomy and applied on celestial images. Solving an image is finding match between the imaged stars and a star catalogue.
1 ⁄ 8000 s: The fastest speed available in production SLR cameras (as of 2013), also the fastest speed available in any full-frame DSLR or SLT camera (as of 2013). Used to take sharp photographs of very fast subjects, such as birds or planes, under good lighting conditions, with an ISO speed of 1,000 or more and a large-aperture lens.
