Let's try taking a Dark Frame with the Tracking CCD to see how it's different:
• In the Camera Setup command set the Active CCD to Tracking.
• Use the Grab command to take another Dark Frame.
• Visually inspect the image. First off you'll notice it's quite a bit smaller (640 x
480 pixels). In addition to the effects noted in the Imaging CCD you'll probably
notice a general brightening from top to bottom. This is typical for interline
CCDs like the Tracking CCD and again will repeat and subtract out of your final
images.
Further Investigations
At this point we refer you to the CCDOps Manual on the CD ROM for further learning
about getting the most out of your STX CCD Camera. We also suggest you join the
SBIG Group on Yahoo to learn from and interact with other users.
2.3. Specific Activities
This section describes some of the unique features of the STX such as Ethernet control and
Autoguiding.
Ethernet Configuration
The STX allows communications to the PC with either USB or Ethernet. While USB
offers faster image downloads Ethernet allows longer cable runs between the PC and the
Camera, not being limited by the 15 foot USB cable length.
The STX comes configured by the factory to have a fixed IP address of 192.168.0.100
but can be configured by CCDOps for other addresses or to use DHCP. Use the
commands in the STX sub-menu of the Misc Menu to configure the STX.
To Establish a link over Ethernet with CCDOps use the Graphics/Comm Setup
command in the Misc menu and set the Interface to Ethernet and either fill in the
Camera's IP address or click the Detect button to search for it.
Web Browser
The STX has an embedded web server built into it and can be controlled by your favorite
Web Browser. This gives the STX support on all systems with the minimum requirement
of a Web Browser. The factory default URL of the STX home page is:
If you've changed the Camera's IP address or are using DHCP the URL will be based on
the assigned IP address.
Making the Autoguiding Connection
Like all SBIG cameras, the STX has an Autoguider port that can be connected to your
Telescope. Use the supplied 6-pin phone-jack based Autoguider Cable to connect the
STX to your Telescope.
