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.
Although the first version of the software was a tool used mainly by professional astronomers, efforts have been made to bring the tool to the homes of educators and students. The FITS Liberator has become the industry standard for professional imaging scientists at the European Space Agency (ESA), the European Southern Observatory (ESO), and ...
A dark frame is an image captured with the sensor in complete darkness (i.e. with a closed shutter or the lens and viewfinder capped). Such a dark frame is essentially an image of noise produced by the sensor. A dark frame, or an average of several dark frames, can then be subtracted from subsequent images to correct for fixed-pattern noise. [1]
Photo Ninja is a raw image processing software by PictureCode, first released as a finished product in September 2012. [1] It includes Noise Ninja noise reduction algorithms. Development of Noise Ninja as a separate product was discontinued when Photo Ninja was introduced.
The process relies on the subject (e.g. a planet) being unchanged between photographs, so that any differences can be assumed to be random noise or atmospheric interference. The stack of images can be in the form of individual consecutive shots or from frames of a movie camera trained on the scene. [5] [6]
Montage is a software toolkit used in astrophotography to assemble astronomical images in Flexible Image Transport System (FITS) format into composite images, called mosaics, that preserve the calibration and positional fidelity of the original input images. [2] It won a NASA Space Act Award in 2006. Montage was developed to support scientific ...
Guerra Cryogenic Camera ad in May, 1974 Sky & Telescope. Cold camera photography is a technique used by astrophotographers to reduce the electronic noise that accumulates during long exposures with the electronic sensors in DSLRs and dedicated CMOS or CCD astro-cameras. Cooling is usually accomplished with a Peltier thermo-electric cooler.
The high sensitivity image quality of a given camera (or RAW development workflow) may depend greatly on the quality of the algorithm used for noise reduction. Since noise levels increase as ISO sensitivity is increased, most camera manufacturers increase the noise reduction aggressiveness automatically at higher sensitivities. This leads to a ...
