More robust algorithms include better alignment of poor quality
(blurred, poorly tracked, …) image data, more reliable astrometry
directly on celestial poles etc. The Photometry tool, thank to which
the SIPS abbreviation exists (SIPS means Scientific Image Processing
System), underwent numerous improvements, like ability to filter stars
listed in the star sheet etc.
Newly supported device classes include for instance weather
Standalone filter wheels (filter wheels not controlled by the
camera) are newly supported. Lates Moravian camera models and versions
are supported natively, including models with built-in GPS
Reworked GUI is highly configurable (refer to the Appendix A of the
SIPS User’s Guide for details, please).
Also, the GUI was simplified and streamlined – functionality
previously implemented in standalone tool windows moved directly to
ribbons to be readily available (for instance Image transform) or
modal dialog boxes (for instance New FITS Header definitions). The new
GUI allows to “minimize” tool windows while they are still active
(like automatic guiding or handling of the main imaging camera), not
to occupy desktop space.
Existing functions like software binning of image list
transformations were extended with new options and parameters.
The Remote Access Web Server publishes a SIPS REST API (sometimes
denoted as RESTful API), which can be used to control SIPS from
web browser or from a Python script).
application, which connects to the SIPS REST API and allows remote
control of SIPS observing sessions from any web browser, regardless if
it runs on a full-fledged desktop PC, laptop, tablet or on a mobile
In fact, this client is another version of SIPS, implemented in
The Program Editor tool is designed to create and run scripts,
written in the SIPS internal scripting language SPL (SIPS Programming
Language), to control observation sequences. The SPL is designed to
provide all necessary features to express any algorithm, but to be
understandable even by beginners without previous programming
Still, to be useable and productive, SPL needs to implement many
concepts like typed variables, procedures and functions with parameter
passing, program module imports etc. These concepts need to be
understood for any programmer using SPL to create scripted observing
There are many more new features in SIPS v4. Download it for free
