Quick Button Shortcuts
Five preset button icons are available as shortcuts to setting multiple parameters
at the same time.
Pressing the icon button will set multiple parameters to enable quick setup times
and helps tailor camera settings to best match user's telescope configuration.
Users can modify settings within the submenus and then press the save button
for the software to assign current settings to that particular Preset button.
The settings that are saved and can be recalled via preset buttons are:
• ALC
• Fixed Shutter
• AES
• Slow Shutter
• AGC
• Peak Control
• Priority
luminance Menu
alC – auto luminance Control
Auto Luminance Control (ALC) indicates the image sensor's ability to automati-
cally adjust in diverse lighting conditions to yield the most vivid video image
possible.
When ALC is active AES will be turned off automatically.
Fixed Shutter
When Fixed Shutter is active AES will be turned off automatically.

Figure 14. Luminance submenu.
When Fixed Shutter is active the following shutter speeds are available.
NTSC: (1/30s ~ 1/1000s)
1/30, 1/50, 1/60, 1/100, 1/120, 1/180, 1/350, 1/500, 1/750, 1/1000, 1/2000,
1/4000, 1/10000
PAL: (1/30s ~ 1/1000s)
1/25, 1/50, 1/60, 1/100, 1/120, 1/180, 1/350, 1/500, 1/750, 1/1000, 1/2000,
1/4000, 1/10000
Shutter speed should be selected to best suit the object being observed and the
telescope being used.
For low light objects Fixed Shutter should be turned OFF.
aES – auto Electronic Shutter (rolling shutter)
AES is used when a manual or fixed iris lens is fitted and the shutter speed will
respond to the amount of light to keep the signal at optimum level.
AES allows changing the iris level automatically without using the auto iris lens.
Note: AES is not normally used for astronomy.
Slow Shutter (Sense up)
Sense-Up: An image processing technology 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.
The minimum frame integration is 1/15 second for NTSC (1/12 for PAL).
The maximum frame integration is 8 seconds (NTSC and PAL).
Set Fixed Shutter SPEED (ALC) to OFF for sense-up frame integration.
