My primary imaging system consists of an ST-8e and CFW-8.
Characteristics of the ST-8e: The effects of temperature and time of exposure on dark current(ADU's):
Effect of temperature on Dark +Bias background (ADU's):
Arrival of New Mount: The Paramount ME
Modifications include the addition of a thorium-argon lamp which provide many lines throughout the spectrum for use for calibration using higher resolution gratings, a 1rpm motor for focusing spectral lines and a JMI digital motor which once calibrated allows for rapid and accurate centering of a spectral region to be obtained. All of this is controlled from a console next to the computers.
