DS-336C XL Setup Guide
The Offset value controls the camera's Black Level. Typically, low data values
contain more noise (bad data) than signal (useful data). The user can use this
setting to modify at runtime the cut-off point between signal and noise. The
most appropriate Offset value depends on many factors including the exposure
time, gain value, the target, the binning mode, etc.
Video Mode
The camera can be set to video mode from
the Preferences panel. On Nebulosity's main
menu at the top select Edit > Preferences.
