Sensor Transplant Only.

The SBIG STX-16801 NABG camera is used in Wide Field Photometry, Astronomical surveys, Radiography and Optical testing . The integrated design allows the user to select either Ethernet or high speed USB 2.0 connection to the control computer. The Model STX-16801 uses Kodak’s KAF-16801 CCD with 16 million pixels at 9 microns. The sensor measures almost 37mm square. The STX series has superior cooling to -50 degrees C below ambient with air only. Water-cooling is also possible. STX cameras have internal voltage regulation and may therefore be operated directly from any unregulated 12VDC power supply.

For off-axis guiding, a KAI-340 guide CCD is available in the optional Remote Guide Head, and in the optional STX Guider accessory for the FW7-STX filter wheel.  The STX Guider increases the guider FOV with focal reduction optics.

Product Description

Superior Cooling

stx_proto7-262x0

The STX 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 STX 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 STX achieves a delta of -50C 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.

Variable Speed Fan Control

stxl_fan-1-258x0

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.

User Rechargeable Desiccant

This feature allows the user the greatest flexibility in the field, and avoids having to return the camera to the factory in order to dry the CCD chamber.

Even-illumination Shutter

From our first ST-7 camera, SBIG has incorporated an even illumination shutter for taking short exposure flat field frames. However the rotating disk design becomes rather large with ever increasing CCD sizes.  The STX uses a linear shutter design that reduces overall size and weight, while maintaining even illumination on short exposures with large CCDs.  This is something not found on any other camera with a CCD this large.

Flexible Self-Guiding Options

P1012580ar2

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 STX Guider, which attaches to the FW7-STX filter wheel and adds only 1.1″ of additional back focus distance.  With the guider CCD integrated into the filter wheel, and focal reducing optics to increase the field of view, the optical design is optimized for guiding and everything is controlled through a single interface. The guider connects directly to the camera, and does not require additional power or control cables. The system can be operated by a single software package as one camera.

The StarChaser SC-3 is a new self-contained guiding option with built-in AO support.

Optional AO-X Adaptive Optics

All STX 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. The AO-X requires the use of an STX Guider, StarChaser SC-3, or an off-axis guide assembly with the Remote Guide Head.

For more information please see AO-X.

I2C AUX Port

The STX cameras have a convenient I2C AUX port, which controls all accessories including filter wheels and AO-8T Adaptive Optics accessories..

USB 2.0 and Ethernet

Both USB 2.0 and Ethernet are available on STX cameras. The user does not have to choose the interface at the time of purchase. The STX camera also directly powers and controls all optional accessories including filter wheel, STX Guider, and AO-X Adaptive Optics.

Full Frame Image Buffer

The STX series cameras has a full frame image buffer for storing image data during download. This eliminates any possibility of image artifacts caused by computer processing delays during image download.

Carrying Case

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