RCC dome encoder workaround
Since the lightning strike/overcurrent, several key systems at Piszkéstető are temporarily not operational, including the dome encoder. This means the dome cannot be controlled with the regular commands, or cannot be set to auto mode with rcc dome auto. To circumvent this, a webcam looking at the dome slit has been installed on the side of the telescope and the following method has been devised.
Setting up the ccdsh instances
One of the two main differences is that now we need to ccdsh instances to operate both the telescope and the camera. The first instance is stared with the --no-startup switch:
tibor@m6:~$ ccdsh --no-startup
For the spectrograph camera, the following modules have to be loaded:
CCD> module mod_fli_camera.so --device 172.31.171.98:8853
CCD> module mod_dummy_filter.so
