 == Taking Science Exposures == #obs
+A target must be placed on either the lrs2b or lrs2r markers for the lrs2 to see them.  Once the object is on the correct marker and guiding has been achieved on the guide probe be sure to have the TO retract the acquisition camera.
+It is critical that you log which unit of lrs that the target is on since asking for an lrs2 exposure will read out both the lrs2b and lrs2r.   It is also important to note the observation number that is currently being used.    Do not over-write
+the beginning of the night calibrations.   Perhaps starting the science numbering with 1000 and the start of the night calibration numbers with 100 will avoid this problem?
 There are many ways to take an exposure, the simplest uses Python to issue the expose command.
