pyobs for ZWO ASI cameras
This is a pyobs module for ZWO ASI cameras.
ASI SDK
Download the ASI SDK from https://astronomy-imaging-camera.com/software-drivers and install the libraries from the
appropriate folder in lib/ to /usr/local/lib. Then copy asi.rules to /etc/udev/rules.d/99-asi.rules.
Install pyobs-asi
Clone the repository:
git clone https://github.com/pyobs/pyobs-asi.git
cd pyobs-asi
Install it with uv:
uv sync
Alternatively, with plain venv/pip:
python3 -m venv .venv
source .venv/bin/activate
pip install .
Configuration
The AsiCamera class is derived from BaseCamera (see pyobs documentation) and adds some new parameters:
camera:
Name of camera to acquire driver for.
sdk:
Path to .so file from ASI SDK.
Therefore, a basic module configuration would look like this:
class: pyobs_asi.AsiCamera
name: ASI camera
camera: ZWO ASI071MC Pro
For cameras with cooling, use AsiCoolCamera instead, which adds a setpoint parameter for the initial cooling
setpoint in degrees Celsius:
class: pyobs_asi.AsiCoolCamera
name: ASI camera
camera: ZWO ASI071MC Pro
setpoint: -20
GUI
For testing a camera without a full pyobs setup, install the optional gui extra:
uv sync --extra gui
and run:
uv run asi-gui [path/to/libASICamera2.so]
Dependencies
- pyobs-core for the core functionality.
- zwoasi as a Python wrapper for the ASI SDK.
- Astropy for FITS file handling.
- NumPy for array handling.
