Available classes

There is one single class for ASI ZWO cameras.

AsiCamera

AsiCoolCamera

class AsiCoolCamera(setpoint: int = -20, **kwargs: Any)

Bases: AsiCamera, ICooling

A pyobs module for ASI cameras with cooling.

Initializes a new AsiCoolCamera.

Parameters:

setpoint – Cooling temperature setpoint.

async get_cooling(**kwargs: Any) → Tuple[bool, float, float]

Returns the current status for the cooling.

Returns:

Enabled (bool): Whether the cooling is enabled SetPoint (float): Setpoint for the cooling in celsius. Power (float): Current cooling power in percent or None.

Return type:

Tuple containing

async get_temperatures(**kwargs: Any) → Dict[str, float]

Returns all temperatures measured by this module.

Returns:

Dict containing temperatures.

async open() → None

Open module.

async set_cooling(enabled: bool, setpoint: float, **kwargs: Any) → None

Enables/disables cooling and sets setpoint.

Parameters:

• enabled – Enable or disable cooling.

• setpoint – Setpoint in celsius for the cooling.

Raises:

ValueError – If cooling could not be set.
