 This module analyzes Allsky images for cloud cover and writes the (zenith) cloud fraction and cloud change into an Influx DB.
-It also includes a web service to query  celestial positions for the limiting magnitude, which is calculated in an intermediate step.

 ## How does it work?
 The module listens for a new image from the configured camera. If a new image has been captured, an image analysis pipeline is run on the image, depending on the solar altitude when the image was captured. Currently there is only a "night" pipeline, which works best after astronomical twilight (solar altitude below -18°).
 This pipeline estimates the limiting magnitude of each pixel based on the visibility of the stars. Pixels are considered cloudy if their limiting magnitude falls below a defined threshold.
