Manuf. No. SBIG STX-630331
SBIG 6.3 Megapixel KAF-6303 CCD Camera with High QE and ABG, STX-630331
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. This difficulty is addressed with two new guiding techniques developed by SBIG and implemented in the STX series cameras: Simultaneous Guiding and Differential Guiding.
Built-in Guiding CCD with Adjustable Focus
Simple self-guiding and control of our Adaptive Optics accessory using just the internal tracking CCD will be a standard feature. The guiding CCD in the STX cameras will be a new KAI-340 CCD with 640 x 480 pixels at 7.4u. As the imaging CCDs get larger, the guiding CCD gets pushed farther away from the center of the optical axis. Depending on the nature of the optical system, this can cause the image on the guiding CCD to be slightly out of focus when the image on the main CCD is in focus. To address this, the new STX cameras will have a user accessible adjustment for changing the focal point of the on-board guiding CCD.
Optional Remote Guide Head
A Remote Guide Head will be optional for the STX cameras. Self-guiding through a separate guide scope or off-axis guider, and control of the Adaptive Optics accessory, can be done using the Remote Guide Head instead of or in addition to the on-board guiding CCD. The same KAI-340 CCD will be used in the new Remote Guide Head made for the STX series cameras.
The external guide head will not only continue to guide while the imaging CCD is downloading an image, but it can be operated simultaneously with the on-board guiding CCD. This allows a unique type of guiding through a separate guide scope that will correct for differential deflection by using the external guider to make fast corrections while the on-board guider makes slow corrections. Differential deflection tends to occur over a longer period of time than drive errors, typically minutes vs. seconds. A long exposure taken with the built-in guider is capable of reaching dim stars without searching, even through narrowband filters, and a long exposure with slow corrections with this on-board guider will correct for the slow differential deflection typically experienced with a separate guide scope. In the mean time, the Remote Guide Head can simultaneously make fast corrections using the brighter stars easily found with a short refractor mounted piggy back to the main OTA. This technique, developed independently, is similar to the technique employed successfully by Italian amateur Filippo Ciferri using two separate cameras for which he deserves full credit. With the STX, however, a single camera and remote head will perform both the fast and slow guiding, as well as the imaging, all at the same time, using a single instance of the control software and only one connection to a computer.
SBIG has a patent pending on a new guiding technique using an artificial guide star. Although artificial stars are used in a variety of techniques on professional telescopes, the SBIG technique is somewhat different and easy to implement on amateur scopes. An artificial star is created near the focal plane of the imaging CCD and an image of this star is retroreflected into a separate guide scope. By using one real star in the FOV of the guide scope and the artificial star image reflected from the main scope, the difference in separation caused by telescope pointing errors is used to make the corrections to the telescope drive. There is no problem with differential deflection and a single CCD external guider can be used to monitor both the real and artificial guide stars. The artificial star image is not seen by the imaging CCD.
USB 2.0 and Ethernet
Both USB 2.0 and Ethernet will be available on each STX camera. The user will not have to choose the interface at the time of purchase. The STX cameras will have the same convenient I2C AUX port that we use on the ST and STL cameras for power and control of accessories such as filter wheels and Adaptive Optics, and will operate from any unregulated 12VDC source.
In similar fashion to the STL cameras, the STX will internally regulate a 12VDC supply so that the camera can be connected directly to any unregulated 12VDC source such as a car battery. The camera will have 4 power LEDs that will 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.
Full Frame Image Buffer
The STX series cameras will have a full frame image buffer for storing image data during download. The STX will be able to image during download process. We are exploring the possibility of using this buffer for pre-processing pixel defects based on a defect map provided by the CCD manufacturer, at the user’s direction.
Multiple A/D Channels
Having multiple A/D channels available makes a number of things possible. For instance, the STX cameras will be able to download and guide, or guide with two guiders all at the same time. Guiding can continue uninterrupted using the Remote Head during an autograb sequence, or an automated LRGB sequence, just as it would if you were using a separate camera or autoguider independent the camera.
Our engineers have modeled an optimum cooling design for this camera using a large custom pin grid array heat sink mated directly to the hot side of the 2 stage TE cooler to achieve maximum heat dissipation with a single large fan. The STX is designed to achieve a minimum delta of -50 degrees C with air only, and a similar delta with water 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. Chilled water may also be used alone or with the fan for even greater cooling.
Starting with the first ST-7 camera, SBIG has incorporated an even-illumination shutter for taking short exposure flat field frames on all self-guiding cameras. However, the rotating disk design becomes rather large with ever increasing CCD sizes. Therefore, a new shutter design will be introduced with the STX series that reduces the overall size and weight of the camera body, while maintaining even illumination on short exposures with large CCDs.
Variable Speed Fan Control
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.
Focusing Mechanism of Tracking CCD
As CCDs get larger, the tracking CCD is moved farther off-center from the optical axis. This can result in out-offocus guide stars. In order to compensate for different telescopes and different tracking CCD locations, the built-in guider will have a small, user accessible, focus adjustment for the tracking CCD. Once this is set for a particular camera and scope combination, it will not be necessary to change it.

Special Order Item
Takahashi Mewlon-300CRS Dall-Kirkham OTA Telescope, TLK3502
The Mewlon-300CRS is the largest in the corrected Dall-Kirkhams made by Takahashi. The internal 3-element ED corrector transforms the M-300 into a corrected flat-field instrument. An integral stepping motor control secondary focusing, which Takahashi first introduced in 1990, is now an advanced computer controllable focusing system. The focus system called Active Focus can be computer controlled by ASCOM compliant programs such as Focusmax and Maxim DL.
The Active Focus system, ASCOM compliant, enables the secondary focusing to be computer controlled by programs such as Focusmax and Maxim DL. This system includes backlash control as well. A hand control that can focus manually or with USB connector to a PC is included.
Additionally to aid cooling a low vibration three fan system in standard equipment. This system uses three sensors: one on the mirror, a second inside the tube and a third outside the tube to properly measure ambient temperature which enables the cooling system to operated either manually with the hand control or by PC. A convenient USB B connection is supplied on the hand controller for easy computer connection. For manual operation the fan button is pressed to turn on the cooling system. Focusing is powered by a 12v AC power supply for computer focusing or four AA batteries for manual focusing. A free driver is used to enable computer controlled focusing.
The M-300CRS is a flat field corrected telescope that produces a flat field high contrast images and pinpoint star across the entire field due to its three element ED permanent corrector. This is a perfect match for the new Takahashi UW flat field 90 eyepieces.
The Mewlon Series of Dall-Kirkham Telescopes by Takahashi combines refractor-like performance in a larger folded optic reflector design. The standard EM-200 or optional NJP mounts provide a stable, accurate platform for the M-210. The integral polar alignment telescope and R.A. axis level make accurate polar alignment to within 2 arc minutes of the celestial pole quick and easy. The reticle is designed to be used in either Hemisphere until the year 2030. No other manufacturer uses such a highly accurate polar telescope. The Mewlon series of Dall-Kirkham Cassegrain telescopes from Takahashi offer the experienced observer a level of performance and portability not found in other Cassegrain telescopes mass produced for amateurs. The classical Cassegrain telescope offers excellent performance, but they are extremely expensive to produce at large apertures. By concentrating on the Dall-Kirkham Cassegrains, the Mewlon telescope offers a professional level of performance within reach of most amateurs.
