RegiStax isimage processing software foramateur astrophotographers, released asfreeware, designed to run underWindows,[1][2][3][unreliable source?][4][unreliable source?] but which also runs onLinux, underwine.[1]
Its purpose is to produce enhanced images ofastronomic observations through combining consecutive photographs (an image "stack") of the samescene that were taken over a short period of time. The process relies on the subject (e.g. aplanet) being unchanged between photographs, so that any differences can be assumed to be random noise oratmospheric interference.
The stack of images can be in the form of individual consecutiveshots or fromframes of amovie camera trained on the scene.[5][6]
Cor Berrevoets (Netherlands) began development of the program about 2001,[7] and it was released on 19 May 2002.[8] This initial release (version v1.0.0) had facilities for stack alignment, grading and selection of the images to be merged, and image enhancement using techniques such as wavelet processing.[9][10] The program was regularly updated by its author and on 6 June 2004 a multi-lingual version was begun (v3) and the program was later available in 15 different languages.[11] To date (September 2022) the latest release is v6.1.0.8 (6 May 2011) which was contributed to by a team of 9 people.
In 2023 the author started work on a new freeware program based on RegiStax called waveSharp.[12] This software does not align/stack images but retains most of the functionality of RegiStax and is available for Windows and Linux. In december 2023 waveSharp 1.0beta was released followed up in december 2024 by waveSharp 2.0.
RegiStax has been written and compiled to run under Microsoft Windows, but [...] RegiStax can be run under Linux via wine.
The package that emerged head and shoulders above the compeditors was written by a Dutchman, Cor Berrevoets and is called Registax.
Registax (by Cor Berrevoets) offers the best lunar and planetary results in a very easy to use package.
RegiStax has been around for a long time and is probably the single reason why amateur astronomy has made huge strides in the last several years.
