Autonomous Allsky camera with Raspberry PI. Part 3: shooting night sky in FITS using QHY5-IIM camera

This is a third part of the Allsky cycle. Please read previous articles to get complete information about this project: Part 1. Autonomous Allsky camera with Raspberry PI: overview. Part 2. Autonomous Allsky camera with Raspberry PI: powering and lightning protection This time I will show my utility and script for shooting night sky and processing of the images.

Autonomous Allsky camera with Raspberry PI. Part 1: overview.

Allsky (or weather) camera is one of the most important part of the modern observatory. It’s very important to monitor sky condition during night observations, especially when observatory is remote controlled or should be fully automatic. Different vendors provides different solution. But all they are share the same problems: very high prices, lack of autonomy (PC is required) and lack…

Connecting HTU21D temperature/humidity sensor to the Raspberry PI using simple C i2c interface

Previously in my projects I’m always used well known DHT22 (AM2302) temperature/humidity sensors. But I found that this sensors is not very stable and subject to hungs. In my case this device is worked about two weeks and then stops responding untill power rebooted. This is absolutely unacceptable on some distant and autonomous devices. After some googling I found that…
