This CCD camera is currently the main imaging instrument on the RCC telescope.
An SI 1100S camera with Johnson-Cousins B,V,R,I and Sloan u,g,r,i,z filters is currently mounted on the telescope yielding an approximately 16'x16' FoV. Camera control is implemented via
ccdsh after the camera drivers are loaded. This can be done with the following command:
This line can also be included in the user's local startup script in the home directory. The camera driver file contains the followings:
module mod_sicamera.so module mod_ace_filter.so define filter 1 B "Bessel B" define filter 2 V "Bessel V" define filter 3 R "Bessel R" define filter 4 I "Bessel I" define filter 5 C "Clear" define filter 6 u "Sloan u" define filter 7 g "Sloan g" define filter 8 r "Sloan r" define filter 9 i "Sloan i" define filter 10 z "Sloan z" define filter 11 E "Empty"
The first two lines load the camera and filter modules respectively, and the next eleven defines the filters.
The basic parameters of the camera and its CCD are the following:
The third column of the driver file contains the filter positions, the fourth the names which the filter can be referred to when using the
set filter command, and the fifth contains the names.
acectrl --stop, and move the guider mirror to the side:
acectrl --guide-xstage-reset, before starting the observations.
set focuscommand within
sequence -n dark 10*[dark,20,delay=2]and then interrupt the sequence (with
Ctrl+C) while the system is delaying there -- in this example, for 2 seconds.
