# '''Target Acquisition:''' TO DO
# '''Exposure Configuration:'''<br /> Select the desired configuration for each setting using the dropdown menu below the relevant heading, then press the SET button to issue the command to the camera.
#*'''Binning:''' Options are 1x11×1, 2x22×2, 3x33×3, and 4x44×4.
#*'''Gain:''' High (faint objects), medium, and low (bright objects)
#*'''Rate (readout rate):''' Fast (5 MHz) - read-noise of 13.6 electrons, and slow (0.05 MHz) - read-noise of 3.3 electrons (see Andor spec sheet link at the top of page)
#**'''Abort:''' Aborts the current exposure.
#*'''CCD Temperature Control:''' Displays the current CCD temperature, and buttons for cooling down and warming up. The camera takes 10 - 15 minutes to cool, and will stabilise at approximately -70 &ordm;C. Cool the camera at the start of observations and warm it up once you are done.
# '''Image Display:'''<br /> This #*'''contains an image display of the last completed exposure, using [https://js9.si.edu/ JS9].'''#*'''A red and blue circle will appear where the preset values are for the pixel positions for the narrow and wide slit locations. Known bug: only appears after the second image is taken and only displays correctly for 1×1 binning.''' #*'''TIPS: TODO.'''
''Note: It is advisable that DARK frames should be taken with the shutter in the "ALWAYS CLOSED" mode. BIAS frames (especially if multiple frames are taken) SHOULD ALWAYS be taken with the shutter in the "ALWAYS CLOSED" mode since this will deactivate the iris-shutter in the closed state and prolong the lifetime, see also [[#Suitable_Uses|high cadence imaging]] in the Suitable uses section at the top of this page.
