The new STX Series from SBIG will have new imaging CCDs, new tracking CCD, dual interface, greater cooling, faster download rates, new guiding techniques, and more.

Some Design Features of the STXUSB 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.12VDC Operation: 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. Improved Cooling: 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. Even-illumination Shutter: 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.Desiccant + Gas Purge Ports: 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 with inert gas, we have designed the chamber to accept both a rechargeable desiccant plug similar to our current ST and STL cameras, and a gas purge port for purging the chamber with Argon or other inert gas if desired. The camera is designed to operate normally without the need of inert gas in the CCD chamber, but the option to use such gas will be up to the user. 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-of-focus 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.Opto-isolated Relays for Telescope Control: These isolated relays will not require an external Relay Adapter box or other opto-isolator to work with virtually any telescope mount that accepts autoguider inputs for guiding control. 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. Adaptive Optics and Filter Wheels: Due to the sizes of some of the planned CCDs, a new AO and Filter Wheel will be designed for the STX cameras. Filters for most of these chips will need to be larger than 1.25". Some need to be larger than 2" or 50mm round.
ну.. если есть 14-15 тыс.$ в резерве на камеру, то наверное - эта камера будет очень приятным подарком Кстати, у этой камеры есть некий механизм регулировки фокус-дефокус гид чипа. Интересно это как сделано: механически или электронно?
Не, ну может не прям вот эту...
Ну, тут можно одно сказать - надо брать...
Только сначала нужно взять какой нибудь бетоненфокусер
Цитата: Max_canaryskies от 18 Дек 2009 [19:54:03]Ну, тут можно одно сказать - надо брать... Только сначала нужно взять какой нибудь бетоненфокусер и бетонентелескоп впридачу. 2.2 кг на стандартном плече в ~200мм, воткнутое в дристлявый двухдюймовый крефорд, зрелище достаточно жалкое.
у всех камер СБИГа есть возможность быть примонтированными к рельсе (ласточкин хвост или спец.рельса) на которой крепится телескоп. Проблем не должно быть.
2,2 кг + колесо фильтров. Это действительно далеко не каждый кассегреновский задник выдержит.
Антон, а для чего вот эти отверстия и крепеж у камеры ST, тоже самое у STL?
Цитата: rom67 от 19 Дек 2009 [22:28:31]Антон, а для чего вот эти отверстия и крепеж у камеры ST, тоже самое у STL?У STL щели такой вообще нет, есть только дырка с фоторезьбой.У ST в дырке та же фоторезьба а зачем эта щель хз. Под ней сразу печатная плата и бумажка наклеена, что мол больше несколких миллиметров в дырку не совать. Скорее всего для охлаждения.Так что нету у сбига никаких хитрых рельсов, домкратов и такелажа для поддержки камер.
