In various embodiments, a telescope comprises a telescope body, telescope optics, a two-dimensional sensor array, and power supply circuitry. The power supply circuitry comprises a switching power supply configured to provide power to the two-dimensional sensor array and sensing circuitry. During at least a portion of data acquisition, the switching power supply is shut off and the two-dimensional sensor array is powered by a non-switching power source, thereby reducing noise.
