Overview

What Are Modules

Modules are Python components that extend the functionality of Allsky. They typically fall into one of several categories:

• Data-enhancement modules — These add extra information that can be used in overlays. For example, the Solar System module provides details about celestial objects such as the Moon’s position.
• Hardware-control modules — These interact with external devices. A common example is the Dew Heater module, which reads sensor data and automatically adjusts the dew heater.
• Image-processing modules — These operate on the captured images. Some modify the image itself (such as the Mask module), while others analyse the image to generate additional overlay data, such as the Star Count module.

Available Pipelines (flows)

There are 5 pipelines available in Allsky.

Pipeline	Description
Daytime	Used whilst Allsky is capturing images during the day
Nightime	Used whilst Allsky is capturing images during the night
Day to Night	Used when Allsky transitions from Daytime to Nighttime capture
Night to Day	Used when Allsky transitions from Nighttime to Daytime capture
Periodic	Run periodically outside of the main Allsky capture process

Each pipeline can run a series of modules in sequence. By default, the Daytime and Nighttime pipelines include the core modules that load and save the captured image; these core modules cannot be removed. All other pipelines start empty. You can use the Module Manager to add additional modules to any pipeline as needed.
