This article links the descriptions of several auxiliary devices installed on the RCC telescope.

On-axis fiber camera

See the article Spectrograph fiber camera for more details.

Manual fine-tuning on the telescope position

While positioning, the program rccpanel enables the observer to manually adjust the position of the star with respect to the fiber. This program can be ran on m5 with the following command from the system shell (i.e. start from xterm or a VNC session):

rccpanel --speed n &

where n is the slewing speed in arcsec/s. The value of n can have a maximum value of 10 (otherwise, i.e. specifying larger numbers, it will be truncated down to 10). A very simple GUI panel will pop up where the observer can move the telescope in four directions by simply pressing buttons. Note that the value of 10 is relatively large for very precise manual positioning.

Some important notes:

  • To run the rccpanel program, the tracking must be switched on. Namely, run the command set mount track on from CCDSH before pressing the buttons of this panel.
  • CCDSH must be started with the successfully loaded module mod_criorcc.so in order to use rccpanel. Otherwise, staring rccpanel would fail with a connection error.
  • Running autoguiding together with rccpanel might cause glitches, that can be solved only by restarting ccdsh.

Autoguiding

See the page RCC autoguiding for more details about the available options for autoguiding.
