QHYCCD module for pyobs

This is a pyobs module for QHYCCD cameras.

System dependencies

On Debian/Ubuntu, plus the QHYCCD driver:

sudo apt install build-essential python3-dev libusb-1.0-0-dev libcfitsio-dev

Install pyobs-qhyccd

Clone the repository:

git clone https://github.com/pyobs/pyobs-qhyccd.git
cd pyobs-qhyccd

Install it with uv:

uv sync

Alternatively, with plain venv/pip:

python3 -m venv .venv
source .venv/bin/activate
pip install .

Configuration

The QHYCCDCamera class is derived from BaseCamera (see pyobs documentation) and adds a few new parameters:

setpoint:
    The cooling temperature setpoint in degrees Celsius (default: -10).
params:
    Optional dictionary of additional QHYCCD control values to set on connect.
cooling_step:
    Maximum change in setpoint per cooling adjustment, in degrees Celsius (default: 1.0).
cooling_wait:
    Time to wait between cooling adjustments, in seconds (default: 60.0).

A basic module configuration would look like this:

class: pyobs_qhyccd.QHYCCDCamera
name: QHYCCD camera
setpoint: -10

GUI

For testing a camera without a full pyobs setup, install the optional gui extra:

uv sync --extra gui

and run:

uv run qhyccd-gui

Dependencies

pyobs-core for the core functionality.
Astropy for FITS file handling.
NumPy for array handling.
