Editing Astrophotography (section)

==== Filters ====

: Filters can be categorised into two classes; broadband and narrowband. Broadband filters allow a wide range of wavelengths to pass through, removing small amounts of light pollution. Narrowband filters only allow light from very specific wavelengths to pass through, blocking out the vast majority of the spectrum.
: Astronomical filters usually come as sets and are manufactured to specific standards, in order to allow different observatories to make observations at the same standard. A common filter standard in the astronomy community is the Johnson Morgan UVB, designed to match a CCD’s color response to that of photographic film. However there are over 200 standards available.<ref>{{Cite book |last=Gallaway |first=Mark |title=An Introduction to Observational Astrophysics |publisher=Springer Nature Switzerland AG |year=2020 |isbn=978-3-030-43551-6 |edition=2nd |pages=17–19 |language=English}}</ref>

{{urs|date=December 2021}}
Fast [[Internet access]] in the last part of the 20th century, and advances in computer-controlled telescope mounts and CCD cameras, allows use of 'Remote Telescopes' for amateur astronomers not aligned with major telescope facilities to partake in research and deep-sky imaging. This enables the imager to control a telescope far away in a dark location. The observers can image through the telescopes using CCD cameras.

Imaging can be done regardless of the location of the user or the telescopes they wish to use. The digital data collected by the telescope is then transmitted and displayed to the user by means of the Internet. An example of a digital remote telescope operation for public use via the Internet is [[Bareket observatory|The Bareket Observatory]].
