(0.67 = 2 / 3, 2 = 4 / 2). In summary, we are using Nyquist as a starting point, with a slight tweak, because we are typically sampling very small, circular, stars.

WebIn SBIG’s AO-7, a tip-tilt mirror is used to make fine corrections to the position of a star to hold the image fixed on the CCD during the exposure. The tip-tilt mirror has magnets on the back, which interact with the current flowing through a set of voice coils on the AO module housing to rapidly move the mirror. edwin araque
Backfocus requirements for SBIG STT 8300 with FW8?
WebThe AO-X requies minimal backfocus while offering a large 3″ aperture optical element, which is large enough to cover all sensors available in the STX, STXL, and Aluma AC series. The AO-X requires an off-axis guide camera behind the device and in front of the filter wheel (FW8S-STXL or FW7-STX), such as the StarChaser SC-3.
