New Software Included!
Starting October 1, 2019 all new SBIG STXL series cameras now include a license for our renowned MaxIm LT software, a $200 value, at no extra cost.
Self-Guiding in Front of Filters
It is well known that the advantage of easier guiding through a separate guide scopes is often limited by differential deflection of the guide scope relative to the main optical axis due to mechanical flexure or shifting of the mirror in the main OTA.
We solved this problem by introducing the StarChaser SC-3, which attaches to the FW7-STX filter wheel and adds only 0.87″ of additional back focus distance. With the guide sensor in front of the filter wheel, the optical design is optimized for guiding.
The StarChaser SC-3 includes built-in AO support.
Micron-Precision Filter Wheel
In addition, STXL filter wheels are designed with a same precise positioning mechanism. With precise positioning, a filter is returned and held in precisely the same position every time it is rotated into the optical path, even after a loss of power and no matter how many times the filter wheel has moved. We measured this accuracy at better than 5 microns (less than one pixel).
USB 2.0 and Ethernet Interface
The STXL series has both USB 2.0 and Ethernet interface capability for the greatest versatility with a variety of computer systems. Users do not have to choose between the two. The Ethernet interface makes control of the camera over a network easy and less expensive than requiring a local computer to be controlled remotely. Moreover, the camera has a built-in web server. Also, with Ethernet, no camera drivers need to be installed. The STXL camera has a built-in web server that can be accessed from any browser.
The STXL uses an innovative pin fin heat sink. This design is the most efficient for dissipating heat per given volume, and while it is more expensive than typical parallel fin heat sinks commonly round elsewhere, it provides superior performance and minimizes size and weight at the same time. This is one of the reasons the STXL camera weighs less than competing cameras with similar cooling performance. The new heat sink is an optimized design for this camera using a large custom pin fin heat sink mated directly to the hot side of the 2 stage TE cooler to achieve maximum heat dissipation with a single large fan. In less than 5 minutes the STXL achieves a delta of -60C using air cooling only.
Water Circulation Ready
While the design is aimed at sufficient cooling without water assist, it is possible to use water instead of air or in addition to air for optimum cooling. Using water instead of air will not require the use of a fan.
Since the early days of the original ST-7 camera, SBIG has been providing even-illumination shutters in our cameras – something not found in the majority of other astrophotography cameras. “Even-illumination” means that the shutter mechanism is designed to open and close in such a manner that it does not change the proportion of light falling on the sensor due to the shape or motion of the shutter itself. This is what one finds for instance with an iris type of shutter that opens-up starting at the center and closes over the center last.
User rechargeable desiccant
In order to allow the user the greatest flexibility in the field, and to avoid having to return the camera to the factory in order to purge the CCD chamber, we have designed the chamber to accept a rechargeable desiccant plug.
Full Frame Image Buffer
The STXL series cameras have a full frame image buffer for storing image data during download. This prevents possible corruption of the image due to processing delays in the main computer during download.
Variable Speed Fan
If the user desires air cooling only, the fan speed is controllable through software. Variable speed control allows the user to “tune” to fan to eliminate any resonance with the user’s telescope thus suppressing harmonic vibrations.
I2C AUX Port
The STXL cameras have a convenient I2C AUX port, which controls all accessories including filter wheels and AO-8T Adaptive Optics accessories.
Tracking Relay LED indicators
This handy set of 4 LEDs will tell you at a glance if the camera is issuing corrections to the mount in +X, -X, +Y or -Y directions during an imaging session.
The STXL will internally regulate a 12VDC supply so that the camera can be connected directly to any unregulated source such as a car battery. Four power LEDs indicate if the supply voltage drops to 11, 10 or 9 volts and when it is “good.” Operation of the camera is possible with a supply voltage of 9.1 to 14 volts DC. Other LEDs indicate camera status and operation of the relays during guiding.
STXL models can connect to a Remote Guide Head, which is suitable for piggyback guide telescopes or off-axis guider devices. It connects directly to the Guide Head port on the STXL camera, which provides all power and control signals. This provides a convenient, integrated package and minimizes mount cabling.
The StarChaser SC-3 is a new self-contained guiding option with built-in AO support.
Optional AO-X Adaptive Optics
All STX and STXL models can operate with the AO-X Adaptive Optics accessory. The AO-X uses a tip-tilt window to quickly and precisely adjust the image position in response to autoguider feedback. With Adaptive Optics there is no backlash, stiction, or lag, and the movements are precise and accurate. This allows the AO-X to not only remove the effects of periodic error, drift, and wind gusts, but also reduce the effects of atmospheric seeing.

All STXL cameras include a deluxe carrying case, universal power supply, power extension cable, USB cable, guider cable and software.
