4. Manual camera settings
Once you are comfortable with Origin's basic operation, you can try using manual camera settings instead of automatic ones. You can
customize the duration of the sub-exposures and the ISO (i.e., gain) setting.
To access the manual camera settings, press the up chevron above the Start Imaging button in the Camera View (Figure 11). Press
the Auto button on the far left to toggle from Auto to Manual camera settings.

Sub-exposure Duration
To manually set the sub-exposure duration, press the "Exposure" button. To set the number, tap it, and a number keyboard will appear.
You can also use the "+" and "-" buttons to increment the number. To change the unit of time, tap it. We recommend using seconds
for normal operation at night.
- For exposures under one second, use SnapShot mode (explained later in this manual).
- The maximum sub-exposure time is about 30 seconds due to fi eld rotation from the altazimuth tracking mount, which is normal. If
the object is close to the zenith, you will likely need to use even shorter exposures.
ISO (Gain)
To manually set the ISO, tap the ISO button and select ISO 100, 200 (default), or 2000. Use ISO 200 most of the time. You can try
ISO 2000 if you are imaging from very dark skies or using a narrowband imaging fi lter. Otherwise, the gain will be too high for the
Origin to recognize star patterns, which will cause Origin to fail. If this occurs, Origin will automatically drop down from ISO 2000 to
ISO 200 and display a warning message. You can try ISO 100 for bright targets, like stars or clusters, to minimize noise by sacrifi cing
some signal strength.
