Orion 52188, 52187 instruction manual Digital zoom x2 on or OFF

Sense-Up: An image processing tech- nology which allows user selectable digital slow shutter speeds in order to allow extra light into a camera thereby providing higher sensitivity in low light conditions (Figure 7).

The minimum frame integration (x2) is 1/32 of a second for NTSC (1/40 for PAL).

The maximum frame integration (x256) is 4 seconds for NTSC (5 sec- onds for PAL).

Set SHUTTER SPEED (ALC) to OFF for frame integration.

Low light objects such as stars and the Milky Way require a high value sense up setting such as x256 which gives a total exposure time of up to 4 seconds NTSC (5 seconds PAL).
