10 AUTOSTAR CCD PHOTOMETRY
Figure 2-8. Exposure Setting Window.
Note: Live Exp exposure times can be set shorter than 1.0
seconds; and Long Exp times can be set to steps of 1.0, 1.4, 2.0,
2,8, 4.0, 5.7, 8.1, 11.3, 15, .... seconds. You can use the Live
exposure time for short exposures (up to 15 seconds). For times
greater than 1 second, we suggest using Long Exp.
Leave the Live button clicked for now.
4. Check the dark field subtraction box (Dark Sub).
Note: Leave the Gain and Offset at their default values (Gain =
100, Offset = 50). With these settings, the DSI camera produces
about 1.43 ADUs/electron. The linear range of the camera is up to
about 45,000 electrons; which means with a Gain of 100, the ADU
count is linear to the maximum 16-bit analog-to-digital (A-D)
converter output, or 65,535 counts.
5. In the Image Process box (see Figure 2-9) select Deep Sky.
