Section 1 - Introduction
1. Introduction
Congratulations and thank you for buying one of Santa Barbara Instrument Group's CCD cameras.
The model ST-7XE/XME, ST-8XE, ST-9XE, ST-10XE/XME, and ST-2000XM/XCM are SBIG's fifth
generation CCD cameras and represent the state of the art in CCD camera systems with their low
noise and advanced capabilities, including Kodak's new Blue Enhanced E series of CCDs and high
speed USB interface. We feel that these cameras will expand your astronomy experience by being
able to easily take images like the ones you've seen in books and magazines, of structure never seen
through the eyepiece. SBIG CCD cameras offer convenience, high sensitivity, and advanced image
processing techniques that film just can't match. While CCDs will probably never replace film in its
large format, CCDs allow a wide range of scientific measurements and have established a whole
new field of amateur astronomy that is growing by leaps and bounds.
These cameras include several exciting new features: improved self-guiding (US Patent
5,525,793), high speed USB interface, improved cooling design and more. These cameras have two
CCDs inside, one for guiding and a large one for imaging. The low noise of the read out electronics
virtually guarantees that a usable guide star will be within the field of the guiding CCD for
telescopes with F/numbers F/6.3 or faster. The new cooling design is capable of performance
similar to that which used to require an optional second stage cooling booster. The relay output
plugs directly into most recent commercial telescope drives and is easily modifiable to virtually any
drive system. As a result, you can take hour long guided exposures with ease, with no differential
deflection of guide scope relative to main telescope, and no radial guider setup hassles, all from the
computer keyboard. This capability, coupled with the phenomenal sensitivity of the CCD, will
allow the user to acquire observatory class images of deep sky images with modest apertures! The
technology also makes image stabilization possible through our AO-7, or self-guided spectroscopy
with our SGS.
The new ST-X series of cameras incorporate the following design improvements over their
parallel based predecessors:
Uses High Speed USB vs. Parallel Port for 10X to 15X faster downloads.
Adds a new I2C bi-directional AUX port for future use.
LEDs on the Digital Board show Relay Activations (helpful for troubleshooting).
New Heat Exchanger with Water Circulation Capability built-in.
No firmware ROM to update, software uploads to camera at boot-up.
New capabilities can be added to the camera by replacing the loader driver.
New Boot sequence, LED flashes and fan comes on when firmware upload is complete.
LED flashes when initializing shutter.
Mechanical/electronic design work to reduce shutter errors and stray light.
TC237 autoguider CCD added to the ST-8XE, ST-9XE, ST-10XE and ST-10XME.
Premier software, CCDSoftV5 and TheSky included with each camera.
CCDOPS version 5 camera control software included with major improvements
o Support for USB cameras
o Support for Ethernet (Ethernet to Parallel) for parallel cameras
o Read FITS files
o Save in several formats (including ASCII format that imports to Excel).
o Multiple images open at once
o New universal drivers
Page 3
Section 1 - Introduction
o Works with all 32-bit Windows OS (95/98/Me/NT/2000/XP).
o Version 5 (Gold Icon) can co-exist with Version 4 (Black Icon).
o Focus Mode Dialog has big numbers for peak brightness to aid focusing.
o Added 1xN, 2xN and 3N readout modes to ST-7/8/9/10/1001
o Magnified preview in crosshairs window
o Sharpen preview in contrast dialog.
o Dockable Icon bar.
1.1. Getting Started.
This manual describes the ST-7XE/XME, ST-8XE, ST-9XE, ST-10XE/XME and ST-2000XM/XCM
CCD Camera Systems from Santa Barbara Instrument Group. The first section contains USB driver
installation instructions. The USB driver installation process must be completed by anyone
installing an SBIG USB camera for the first time on a particular computer. If you wish to run your
SBIG USB camera from more than one computer, you must go through the USB driver installation
process for each computer you intend to use.
For users new to the field of CCD Astronomy, Sections 2, 3 and 4 offer introductory material
about CCD Cameras and their applications in Astronomy. Users who are familiar with CCD
cameras may wish to skip section 2 and browse through sections 3 and 4, reading any new material.
Thoroughly experienced SBIG customers may wish to jump right to the separate Software
Manual, which gives detailed and specific information about the SBIG software. Sections 5 and 6
offer hints and information about advanced imaging techniques and accessories for CCD imaging
that you may wish to read after your initial telescope use of the CCD camera. Finally, section 7 may
be helpful if you experience problems with your camera, and the Appendices provide a wealth of
technical information about these systems.
1.2. Installing the USB Drivers for the First Time
If you are installing an SBIG USB camera for the first time use this section to walk you through the
driver installation process. To operate the camera you must first install camera control software
onto your computer or laptop. Your camera comes with two programs: CCDOPS from SBIG and
CCDSoftV5, which was jointly written by Software Bisque and SBIG. CCDSoftV5 is a very
comprehensive program that incorporates many of the camera control functions of CCDOPS.
However, because we use CCDOPS solely to develop and test our cameras we are able to post more
frequent updates for CCDOPS at our web site for free download. You can use either program to
control the camera but we suggest starting with CCDOPS to install the USB drivers and to make
sure everything is working properly and then move to CCDSoftV5 when you are more familiar
with the operations of the camera. Follow the instructions below to install and run the CCDOPS
software and display and process sample images found at our web site.
Please follow these directions IN SEQUENCE. Do not connect the camera to the PC or turn it on
until instructed to do so below. USB drivers can be difficult to install if you don’t follow the
instructions.

Section 1 - Introduction
1.2.1. Installing the CCDOps and the Driver Checker
The first thing you should do in all cases is to install CCDOps version 5 and the Driver Checker
utility. This is relatively simple:
1. Make sure the camera is not connected to the computer. You will do this later.
2. Run the CCDOps Installer. It can be found in the CCDOps directory of the CD-ROM that
came with your camera. Follow the onscreen instructions to complete the installation.
3. First make sure you are the Administrator or have Administrator privileges if you’re
running under Windows 2000, or Windows XP. On Windows XP Home edition you are the
administrator so you don’t have to worry about that. Next run the Driver Checker Installer.
It can be found in the Driver Checker folder of the CD-ROM.
4. Towards the end of the Driver Checker installation the installer will run the utility. This
utility checks to make sure you have the latest version of the SBIG camera drivers installed
on your system. When the SBIGDriverChecker utility is run you’ll see a dialog like:
If you have previously installed CCDOPS you’ll see some entries in the table. Most likely
one or more drivers is not installed or is not up to date. Also if this is the first time you’ve
run the Driver Checker you may get a warning something like “The sbigudrv service can
not be found”. Just ignore this error.
Page 5
Section 1 - Introduction
5. Using the Driver Checker to update your drivers is a two-step process:
A. If you have an internet connection, Click on the
instructions to download the current drivers from SBIG’s Servers. If you don’t have an
internet connection on this machine then make sure you have downloaded the latest Driver
Checker Installer from SBIG’s web site, copied it to this machine and run it.
B. Whether you have an internet connection or not then click the
copy the current drivers to your system and make sure they are properly installed. Some
new computers without parallel ports will report that the SBIGUDRV.SYS was not started.
Don’t worry about that. The SBIGUDRV.SYS is the parallel port camera driver and is not
use with USB cameras.
You may be asked to reboot your system as well. If so, click Done and do so. Otherwise
simply click Done.
6. Follow the instruction in Sections 1.2.2.1, 1.2.2.2 or 1.2.2.3 below depending on the version of
Windows you have on your computer.

Section 1 - Introduction
1.2.3. Getting Started with CCDOPS
• Use Camera->Establish Com Link
lower-right corner of CCDOPS main window where ST-10 is the camera model. You are
now talking to the camera.
• From this point you should follow the software instructions / help menus to Set Up the
camera’s cooling, Focus, Grab images, etc.
. After a few seconds should see “Link:[ST-10]USB” in
1.2.4. To try some functions with sample images:
• Double-click on the CCDOPS icon to launch the program.
• Use the Open command in the File menu to load one of the sample images. A window
showing the exposure time, etc. will appear. Click in it to make it disappear. The image will
show up in its own window.
• Try using the crosshairs. Use the Crosshairs command in the Display menu.
• Use the mouse to move the crosshair around in the image and see the pixel values.
• Close the crosshairs and try inverting the image. Click the Invert item in the Contrast
window.
• Try the photo display mode. Use the Photo Mode command in the Display menu. Click the
mouse to return to the menus.
• Load up the other sample images and display them using the photo display mode. You
have to close any existing image first.
• If you find that the display is too dark or bright, try setting Auto Contrast in the Contrast
window or adjust the background and range parameters to achieve the best display. You may
have to hit the Apply button in the Contrast window to see changes in the Background and
Range
1.2.5. Capturing Images with the CCD Camera
Unfortunately there really aren't many shortcuts you can take when using the CCD camera to
capture images. The instructions below refer you to various sections of the manual.
• Find some relatively bright object like M51, the Ring Nebula (M57) or the Dumbbell Nebula
(M27) (refer to section 3.5).
• Take a 1 minute exposure using the Grab command with the Dark frame option set to Also
(refer to Section 3.6).
• Display the image (refer to Section 3.7).
• Process the image (refer to Section 3.8).
You can use the SBIG Test Lens to take indoor test exposures and get familiar with the camera
operation. Also, if you happened to have purchased a camera lens adapter for your CCD Camera
you can also use that to take test images during the day:
Page 22
Section 1 - Introduction
Camera lens daytime exposure guidelines:
• Close the F stop all the way to F/16 or F/22.
• Set the focus based upon the object and the markings on the lens.
• Take a short (<1 second) exposure with the Grab command.
• Display the image.
• Process the image.
