이 연구용 카메라는 개발 기간 2년이 걸린 완전히 새로운 카메라입니다. SBIG 설계팀은 최고의 기능과 지난 디자인의 아이디어와 최신의 고속 전자 기기 그리고 대형 포맷 CCD(35mm판 화각에 11만 화소)를 제어하기 위해서 USB인터페이스를 채택하였습니다. 새로운 기능은 듀얼 헤드 셀프 가이드옵션을 포함해 전력 입력구조의 단순화하고 가격과 중량감소를 위한 내장형 2인치 필터 휠의 채용입니다.
이들 대형 포맷 카메라는 이전의 카메라에 비해 저려한 비용으로 더 많은 기능을 제공하도록 설계되었습니다. SBIG의 목표는 경쟁사보다 더 저렴한 가격에 넓은 영역과 셀프 가이드 옵션과 대형 필터휠과 같은 고성능의 이미지 시스템를 생산하는 것입니다.
원격 가이드 헤드 옵션을 추가하여 연구용 카메라에 셀프 가이드 능력을 신장시켰습니다. 이미지 CCD에 추가된 TS-237 CCD칩으로 어떠한 환경에서도 셀프 가이드할 수 있습니다.
One guiding CCD is located next to the imaging CCD in our patented design, similar to the self-guiding arrangement in our ST line of cameras. The remote guiding CCD is in a small separate head that attaches to the main camera body by a short cable. There is no separate power supply or communication cable required. The remote head contains its own TE cooler and shutter. With the optional remote guiding head attached to the main camera body, self-guiding is accomplished by selecting either the internal TC-237 tracking CCD or the remote TC237 CCD using the camera control software. The benefits of this flexibility are obvious. Internal guiding eliminates the need for a guide scope and separate autoguider. It also eliminates the problem of differential deflection of the guide scope or differential motion of the primary mirror relative to the guide scope. However, some users prefer to use an external guider when imaging through dark infrared band or narrow band filters, or for RGB color imaging in regions of the sky with sparse guide stars. The remote guiding head may be used in an off-axis guiding accessory or attached to a separate guide scope. There is only one small cable between the remote head and the main camera body. The remote head can be left connected and the user may freely switch between the internal or the remote TC-237 for self-guiding. All the guiding functions are controlled by the same camera software that normally controls the internal guider.

An internal 5 position 2" filter carousel is integrated into the front cover of the camera body. For color, UBVRI, or narrow band imaging simply add filters to the camera's carousel. There is no expensive separate 2" filter wheel to purchase. The filter carousel accepts both 50mm diameter flats and 48mm threaded filter cells. The front cover of the camera is easily removed for changing filters. Since the CCD is in a separate sealed chamber, removal of the front cover to change filters does not expose the CCD to dust or air and the desiccant does not need to be recharged after replacing the cover. Extra carousels may be purchased for quick and easy transition between filter sets. A shutter mechanism is also located inside the camera body, between the filter wheel and the sealed CCD chamber. A custom LRGBC filters set is optional.
We have added an internal 12VDC regulated power supply to the camera for simplified power requirements and greater tolerance of input voltage variation. When operating in the field from a 12V battery, current drain, power cord extensions and cold temperatures may cause the input voltage to drop below 12 volts. The internal regulated supply will accommodate some variation in input voltage (from about 10 volts to 18 volts) and keep the camera operating normally. This will allow for longer power cords to be used with less concern for voltage drops so long as the input voltage stays within a certain range. A set of indicator LEDs will let you know if your input voltage at the camera is getting too low for normal operation. A universal 110VAC-220VAC to 12VDC power supply is also included for operation from virtually any line voltage in the world.
A set of five LED indicator lights on the side panel of the camera provide critical camera status information. The green LED lets you know the camera is booting up and gives camera exposure status during normal operation. One red LED provides a warning if the heat sink gets too hot. This could happen, for instance, if you were running high power to the cooler and the fan failed for some reason. In this case the camera automatically reduces power to the two-stage cooler to prevent damage. One amber LED warns of an input voltage drop to 11 volts or less but the camera will continue functioning normally. The second amber LED warns of an input voltage drop to 10 volts but the camera will still continue functioning normally. The last red LED warns of an input voltage drop to 9 volts or less. In this case, the camera automatically turns off the TE cooler and continues to operate normally without cooling until the voltage drops to the point that the camera shuts down (around < 7 volts).
The standard cooling design utilizes a very efficient two-stage TE cooler for maximum performance with large format detectors. Each camera is also liquid assist ready so that additional cooling in warm climates may be achieved by circulating water if needed. We are currently testing a special magnetic levitating fan to eliminate even the smallest vibration. Preliminary tests indicate that cooling -50 Degrees C below ambient will be achieved with this system.
Every Research Model camera will be shipped in a custom fitted Pelican brand carrying case for superior protection of your equipment. These cases are waterproof, dustproof, crushproof and have a lifetime guarantee from the manufacturer. Each Pelican case has an automatic pressure relief valve and double hinged latches for easier opening. There is ample room inside for the camera, cables, wall transformer and some accessories in the custom cut foam insert. An optional lid pocket is available from Pelican that will hold charts and manuals.
