The outer ring through the TelRad sight is 1 degree, and the inner ring is 0.5 degrees. [Perhaps]
This can be accomplished with a star chart or a knowledgeable individual. It will be necessary to know these coordinates for pointing model creation.
The star should be as close to the center of the TelRad as possible without taking too many iterations.
rush> rshift -t ; this starts tracking if it isn't already
rush> rexpose -t 2 -n star1
A couple of seconds is plenty of time to image a bright star. To view the image, open a separate terminal window and type something like the following:
$ cd /rotse/data/3a1/ ; this could be 3b1, or 3c1 depending on the system
$ ds9 date_star1_3a001.fit
Hopefully the star is in the image! If it is not, then you just have to play around with jiggling a degree or so. If it is, then...
Move the telescope with rshift until the star is centered on the CCD. Remember, the field of view is . Depending on the orientation of the camera, you will have to figure out which axes move the star in which direction. Once these have been discovered, a little post-it note with the axis orientations is helpful to affix to the enclosure monitor.
This star can act as the first star in the pointing model, so record its position to the log.
Adjust the TelRad so that the laser sight is centered on the star, which is centered on the CCD. This will make the following steps much easier.
