INDI QHY currently supports all the QHYCCD cameras and filter wheels. Some of the older camera like QHY8 might have some issues, but all camera released from 2015 onwards are supported.
Both mono and color versions are supported.
Under Ubuntu, you can install the driver via:
sudo add-apt-repository ppa:mutlaqja/ppa
sudo apt-get update
sudo apt-get install indi-qhy
The driver supports capture, binning, setting temperature, gain and offset adjustment, subframing, and control of internal QHY Color-Filter-Wheel (CFW). Moreover, guiding via ST4 port is also supported.
Temperature control is available if the camera is equipped with TEC cooler. Depending on the camera, TEC cooler can be controlled either automatically or manually.
If you directly set the temperature, the driver switches to automatic cooler mode where the cooler power is adjusted by the driver until the desired temperature is reached and kept. Some camera allow manual TEC control where you can directly set the TEC cooler power. In this manual mode, the cooler power is kept constant regardless of the temperature. Manual mode can be useful for advanced users who wishes to slow the cooling process for their camera since the QHY driver starts cooling to 100% when a lower temperature is requested.
You can also enable video streaming and save recording in LuCam SER format or OGV format. When enabling video streaming, the Rate Divisor property decides how many frames to skip before sending it to the client while the FPS sets the desired frames-per-second requested. When tested on embedeed platforms like Raspbeerry PI, the frames due to USB 2.0 limitations are in the range of 12-18 FPS.
The driver can detect and run multiple devices, therefore you only need to run one instance of the driver even if you have multiple CCDs connected. i.e.
indiserver -v indi_qhy_ccd
Once you're connected, you can capture images as FITS from the camera. You can also adjust gain and set temperature if cooling is supported. Images can be downloaded to the client or saved directly to the hard disk. If the CCD has an ST4 port, it should supported guiding via any INDI-compatible guiding application such as Ekos/PHD2.
Amp Glow Control
Some cameras provide a toggle to enable or disable Amp-glow control. However, for most cameras, this setting is already enabled by default in the camera and no control is exposed. That is, amp-glow control is enabled all the time.
There are no known bugs for this driver. If you found a bug, please report it at INDI's bug tracking system at SourceForge. (You can log in with a variety of existing accounts, including Google, Yahoo and OpenID.)
