Section 1 - Introduction Introduction Congratulations and thank you for buying one of Santa Barbara Instrument Group's Research Model CCD cameras. These large format cameras are SBIG's sixth 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, high speed USB interface, internal filter wheel and dual self-guiding modes.
USB driver installation process for each computer you intend to use. This manual describes the STL-1001E, STL-1301E, STL-4020M, STL-6303E and STL-11000M CCD Camera Systems from Santa Barbara Instrument Group. This Section contains a one page Quick Start Guide followed by detailed instructions on handling, connecting and maintaining the camera.
Section 1 - Introduction 1.1.1. Quick Start Guide – Summary Before First Light: 1. Attach the 2” nosepiece or other adapter to secure the camera to your telescope, or the camera lens adapter if you intend to use a lens rather than a telescope. 2.

Page 10
Section 1 - Introduction Standard Items: Main Camera Body - Research Series Camera Body with imaging CCD and built-in and guiding CCD, two-stage cooling, internal filter carousel and high speed USB interface. An accessory plate is fixed to the front of the camera body for attaching nosepiece, camera lens adapter and custom adapters.
Section 1 - Introduction Custom Filters –50mm LRGBC, UBVRI and narrow band filters are available. SBIG’s LRGBC filter set contains both a Luminance and a Clear filter in addition to the RGB filters. The Luminance filter is both UV and IR blocked. The clear filter is not blocked. The RGB passbands have been specifically designed for use with the CCDs used in the Research Series cameras.
Section 1 - Introduction shimmed at the factory to provide a flat mounting surface that is parallel to the CCD. Under normal use, it should not be removed. The rear cover has ventilation slots for air circulation and also holds the water inlet and outlet connectors. Two clear plastic tubes connect the water inlet and outlet fittings on the rear cover to the heat exchanger inside the back of the main body.
Page 13
Section 1 - Introduction POWER from either the universal AC supply or 12VDC cable is plugged into the round 6 pin DIN connector. If you wish to make a custom power cable, the pin outs for the connector may be found in the appendix of this manual.
Section 1 - Introduction 1.1.5. Attaching the camera to a telescope using the 2” nosepiece There are several ways to attach the camera to a telescope. The easiest and most practical way is to simply use the supplied custom 2” nosepiece. This nosepiece is designed to cause minimum vignetting with the largest (35mm format) CCD.
Section 1 - Introduction 1.1.7. Attaching the optional camera lens adapter The optional camera lens adapter may be used instead of the 2” nosepiece if you wish to use any Nikon 35mm camera lens to take wide field images with one of the large format cameras.
Section 1 - Introduction 1.1.9. Optional Relay Adapter Box Some older telescope drive correctors require electronic isolation between the camera and the telescope. Other older correctors may require both normally open and normally closed relays. For these and other events, an optional Relay Adapter Box is available that will convert the TTL relay output from the camera to mechanical relays contained in a separate box that is inserted in-...
Section 1 - Introduction camera and power back up again. The Remote Guiding Head contains a shutter and TE cooler. It is therefore capable of taking dark frames without manual intervention by the user. The 1.25” nosepiece is screwed into female t-threads on the face plate of the head. The nosepiece may be removed and the head attached to an optical system using t-threads instead.
Section 1 - Introduction 1.1.13. Opening the Front Cover - Changing Filters The filter wheel is contained inside the front cover plate. To access the filter wheel remove the eight socket head screws located in recessed slots around the perimeter of the front cover. With the camera lying on its back plate (or on the camera handles if attached), remove the front cover by lifting straight up away from the main body.
Section 1 - Introduction 1.1.14. Regenerating the Desiccant Plug The CCD is housed in a sealed chamber located inside the front of the main body. The chamber is separate from the large front and rear cover plates, so that opening the front or rear cover plates to gain access the filter wheel or to attach/remove the camera handles will not expose the CCD chamber to the environment.
Section 1 - Introduction volts or less the camera will shut down the cooling and continue to attempt to operate until the voltage drops to a point (about 7 - 8 volts) where the camera is no longer able to function normally. 1.1.16.
Section 1 - Introduction 1.1.18. Camera Resolution Resolution comes in two flavors these days. In the commercial world of digital devices, the word resolution is often used synonymously with the number of pixels used in a device. You are used to seeing ads for scanners with a "resolution"...
Section 1 - Introduction 1.1.19. Camera Field of View The field of view that your camera will see through a given telescope is determined by the focal length of the telescope and the physical size of the CCD chip. This also has nothing to do with the number of pixels.
Section 1 - Introduction 1.1.20. Focal Length, Resolution and Field of View From the forgoing we see that neither resolution alone, nor field of view alone, are dependent solely on the number of pixels of a sensor. So when are more pixels better? The key word in the first sentence is “alone.”...
Section 1 - Introduction 1.2. Installing the USB Drivers for the First Time If you are installing an SBIG USB camera for the first time you must install the USB drivers BEFORE attempting to connect the camera to the computer. This is true for each computer you intend to use to control the camera.
Section 1 - Introduction 1.2.2. Capturing Images with the CCD Camera Unfortunately there really aren't many shortcuts you can take when using the CCD camera to capture images. Refer to your software manual for detailed instructions. However, to begin we suggest: •...
Section 2 - Introduction to CCD Cameras Introduction to CCD Cameras This section introduces new users to CCD (Charge Coupled Device) cameras and their capabilities and to the field of CCD Astronomy and Electronic Imaging. 2.1. Cameras in General The CCD is very good at the most difficult astronomical imaging problem: imaging small, faint objects.
2.2.1. Full Frame and Frame Transfer / Interline CCDs In the STL-1301E, STL-1001E and STL-6303E, the CCD is read out electronically by shifting each row of pixels into a readout register at the Y=0 position of the CCD (shown in Figure 2.1), and then shifting the row out through an amplifier at the X=0 position.
Page 29
Section 2 - Introduction to CCD Cameras Figure 2.2 - CCD System Block Diagram As you can see from Figure 2.2, the cameras are completely self-contained. All the electronics are contained in the optical head. There is no external CPU. At the "front end"...

Section 2 - Introduction to CCD Cameras quality. Many man-years and much customer feedback have gone into the SBIG software and it is unmatched in its capabilities. 2.4. CCD Special Requirements This section describes the unique features of CCD cameras and the special requirements that CCD systems impose.
Section 2 - Introduction to CCD Cameras possible readout noise. At 10e to 15e rms per read these cameras are unsurpassed in performance. 2.4.3. Dark Frames No matter how much care is taken to reduce all sources of unwanted noise, some will remain. Fortunately, however, due to the nature of electronic imaging and the use of computers for storing and manipulating data, this remaining noise can be drastically reduced by the subtraction of a dark frame from the raw light image.

However, the system with 36 inches focal length would have a larger field of view and more faint detail due to the faster optic. The STL-1001E, with its 24 micron pixels would have the same relationship at roughly 195 inches focal length.

Section 2 - Introduction to CCD Cameras observer. In addition to the software provided with the camera, there are a number of commercial programs available which will process and enhance electronic images. Images may be made to look sharper, smoother, darker, lighter, etc. Brightness, contrast, size, and many other aspects of the image may be adjusted in real time while viewing the results on the computer screen.
Page 36
Section 2 - Introduction to CCD Cameras images electronically to produce a color composite or RGB color image. The Research model cameras contain internal motorized color filter wheel. When filters are installed in the filter wheel, light entering the camera passes through the colored filter before it strikes the CCD. An object is then exposed using a red filter.
Section 3 - At the Telescope with a CCD Camera At the Telescope with a CCD Camera This section describes what goes on the first time you take your CCD camera out to the telescope. You should read this section throughout before working at the telescope. It will help familiarize you with the overall procedure that is followed without drowning you in the details.
Section 3 - At the Telescope with a CCD Camera up, or the USB port has not yet been properly selected, a message will be displayed indicating that the software failed to establish a link to the camera. If this happens, use the Communications Setup command in the Misc menu to configure the CCDOPS software for the USB.
Section 3 - At the Telescope with a CCD Camera star diameter. This can be tedious. It helps considerably if a pointer or marker is affixed to the focus knob so you can rapidly return to the best focus once you've gone through it. For critical focus, an exposure of about 1 second is recommended to smooth out some of the atmospheric effects.
Section 3 - At the Telescope with a CCD Camera Because the Research Series cameras have regulated temperature control, you may prefer to take and save separate dark images, building up a library at different temperatures and exposure times, and reusing them on successive nights. At the start it's probably easiest to just take the dark frames when you are taking the image.
Section 3 - At the Telescope with a CCD Camera 3.9.2. Sub-Frame Readout in Focus The Focus command offers several frame modes for flexibility and increased frame throughput. As previously discussed, the Full frame mode shows the entire field of view of the CCD with the highest resolution, digitizing and displaying all pixels.
Section 3 - At the Telescope with a CCD Camera 3.9.4. Autoguiding and Self Guiding The CCDOPS software allows the Research Series cameras to be used as autoguiders and self- guiders through the commands in the Track menu. While these systems are not stand-alone like the old ST-4, but require a host computer, they can accurately guide long duration astrophotographs and CCD images with equal or superior accuracy.
Section 3 - At the Telescope with a CCD Camera 3.9.5. Auto Grab The Auto Grab command allows you to take a series of images at a periodic interval and log the images to disk. This can be invaluable for monitoring purposes such as asteroid searches or stellar magnitude measurements.
Section 4 – Camera Hardware Camera Hardware This section describes the modular components that make up the CCD Camera System and how they fit into the observatory, with all their connections to power and other equipment. 4.1. System Components The Research Series CCD cameras consist of four major components: the CCD Sensors and Preamplifier, the Readout/Clocking Electronics, the Microcontroller, and the power supply.
Section 4 – Camera Hardware single 10 minute exposure except that no guiding is required. The reason no guiding is required is that with most modern telescope mounts the drift over the relatively short 1 minute interval is small enough to preserve round star images, a feat that even the best telescope mounts will not maintain over the longer ten minute interval.
Page 47
Section 4 – Camera Hardware If your hand controller is from a relatively recent model telescope it probably has four buttons that have a "push to make" configuration. By "push to make" we mean that the switches have two contacts that are shorted together when the button is pressed. If that's the case then it is a simple matter of soldering the Common and Normally Open leads of the appropriate relay to the corresponding switch, without having to cut any traces, as shown in Figure 4.1 below.
Section 4 – Camera Hardware + relay - relay wiper potentiometer A: Unmodified Joystick B: Modified Joystick Figure 4.3 - Joystick Modification A slight variation on the joystick modification is to build a complete joystick eliminator as shown in Figure 4.4 below. The only difference between this and the previous modification is that two fixed resistors per axis are used to simulate the potentiometer at its mid position.

Section 4 – Camera Hardware PC and Macintosh computer graphics resolutions, the CCDs used in the SBIG cameras offer a good trade off between cost and resolution, matching the computer's capabilities well. Pixel Dimensions - The size of the individual pixels themselves really plays into the user's selection of the system focal length.
Page 51
Section 4 – Camera Hardware twice the signal to noise you would have to increase the exposure 4 times. An STL-11000M with its full well capacity of 50,000e could produce an image with a S/N in excess of 200! Antiblooming – Some SBIG CCD cameras have antiblooming protection. The TC-237 autoguider has antiblooming built into the CCDs.
4.7. Battery Operation The STL-4020M, STL-1301E, STL-1001E, STL-11000M and STL-6303E can be operated off of a 12 volt car or marine battery using a the optional 12V power cord. The camera draws approximately 4 amps from the battery (5 amps with the Remote Guiding Head attached) so it would not be wise to operate directly from your car battery all night without aback up battery.
Section 5 – Advanced Imaging Techniques Advanced Imaging Techniques With practice, you will certainly develop methods of your own to get the most from your CCD camera. In this section we offer some suggestions to save you time getting started in each of the different areas outlined below, but these suggestions are by no means exhaustive.
Section 5 – Advanced Imaging Techniques 5.4. Taking a Good Flat Field If you find that flat field corrections are necessary due to vignetting effects, CCD sensitivity variations, or for more accurate measurements of star magnitudes, try either taking an image of the twilight sky near the horizon or take an image of a blank wall or neutral grey card.
Section 5 – Advanced Imaging Techniques sensational for displaying faint nebulosity with short exposure times. In Auto Resolution Mode, the camera and software will always use High Resolution for all imaging and display functions except when you are in Full Frame Focus Mode. It will then automatically switch to Low Resolution Mode.
Section 5 – Advanced Imaging Techniques 4. Immediately after saving the IMAGE use the Save Track List command on the PC or activate the Track List window on the Mac and use the Save command to save the Track and Accumulate track list. The track list is a file that describes what alignment operations were done to the individual components of IMAGE to achieve the end result.
Page 57
Section 5 – Advanced Imaging Techniques autoguider like the ST-4, but instead requires using a PC to perform the function. These cameras have considerably better sensitivity than the ST-4. CCD autoguiders alleviate you from having to stare down the eyepiece for hours at a time while guiding astrophotographs.
Section 6 – Accessories for your CCD Camera Accessories for your CCD Camera This section briefly describes the different accessories available for your CCD camera. 6.1. Water Cooling The Research Series cameras are equipped with two-stage cooling and a new heat exchanger design that is ready to accept water circulation for additional cooling efficiency, if needed in warm climates.
Section 6 – Accessories for your CCD Camera 6.3. Camera Lens Adapter A camera lens adapter is available for the Research Series cameras. The camera lens adapter allows you to mount a Nikon 35mm camera lens in place of the telescope for very wide field views of the night sky or for daytime terrestrial imaging 6.4.
Section 6 – Accessories for your CCD Camera PC and photo quality color desktop printers that will product photo like prints of your digital images. 6.7. SBIG Technical Support If you have any unanswered questions about the operation of your CCD camera system or have suggestions on how to improve it please don't fail to contact us.
Section 8 – Glossary Common Problems This section discusses some of the more common problems others have encountered while using our CCD cameras. You should check here if you experience difficulties, and if your problem still persists please contact us to see if we can work it out together. Achieving Good Focus - Achieving a good focus is one of the most difficult areas in working with CCD cameras due to the lack of real time feedback when focusing.
Section 8 – Glossary insert a 12-20mm eyepiece, focusing the eyepiece by sliding it in and out of the eyepiece holder, not by adjusting the telescope's focus mechanism. Center the object carefully (to within 10% of the total field) and then replace the CCD optical head. Since the head was fully seated against the eyepiece holder when you started, fully seating it upon replacement will assure the same focus.
Page 65
Section 8 – Glossary CCDs with the antiblooming option can be used to help stop or at least reduce blooming when the brighter parts of the image saturate. Astrometry - Astrometry is the study of stellar positions with respect to a given coordinate system.

SBIG Tracking Interface Cable (TIC-78) Many of the newer telescopes have a phone-jack connector on the drive corrector for connecting directly to an SBIG camera or autoguider. You can interface these telescopes to the Telescope port with our TIC-78 (Tracking Interface Cable), or you can make your own cable.
Appendix B - Maintenance Appendix B - Maintenance This appendix describes the maintenance items you should know about with your CCD camera system. B.1. Cleaning the CCD and the Window The design of SBIG cameras allows for cleaning of the CCD. The optical heads are not evacuated and are quite easy to open and clean.
Appendix C – Capturing a Good Flat Field Appendix C - Capturing a Good Flat Field This appendix describes how to take a good flat field. A good flat field is essential for displaying features little brighter than the sky background. The flat field corrects for pixel non-uniformity, vignetting, dust spots (affectionately called dust doughnuts), and stray light variations.
