To meet the demands of the next generation astroimaging, SBIG introduces the next generation STT Camera System with self-guiding integrated into a Micron-Precision Filter Wheel.At last, a worthy successor to SBIG’s classic round, dual-sensor ST and STL series self-guiding cameras!The new mid-sized STT Series cameras offer features and specifications found in no other astrocamera – of any size. Drawing on all of our previous experience and the best of each of our previous designs over the years, the STT represents the culmination of everything that the astroimager has asked for in an imaging system, packed into a 4.9 x 4.9 x 2.9 inch camera body.STT Camera Series Highlights•S elf-Guiding in Front of filters•L owest Noise 10Mhz Readout <1 sec•H igh Precision 8-position Filter Wheel•U ser Selectable Internal Image Processing•B uilt-in Frost Detection•2-Stage TE Cooling -55C delta T with air•B uilt-in Web Server•F ull Frame Image Buffer•E ven-illumination (photometric) shutter•E thernet and USB 2.0•B uilt-in RBI Pre-flash•L iquid Cooling Capability Standard•T win Variable Speed Fans•M ulti-coated Sapphire Chamber Window•A ccepts 1.25”, 31mm and 36mm filters•U ser Rechargeable Desiccant Plug •H igh Accuracy Temperature Control•E xternal Triggers In / Out•S tatus, Power and Relay Indicators•W indows 32-bit and 64-bit (and Mac) Software•O ptional Remote Guide Head•O ptional Adaptive Optics (AO-8)•P ower Management System•12VDC Operatio nSTT Series Camera SystemMicron-Precision Filter Wheelwith Built-in Self-Guiding CCD The CameraNo CompromisesThe STT Series is a newdesign with everything theastroimager could want ina camera:•F ast, low noise digitizationand a full frame imagebuffer. At 10MHz theSTT downloads a full frame, low-noise 8300 frame in less than a second.Even-Illumination Shutter • S ince its founding, SBIG’s mechanical shutters have been designed for highly reliable, even-illumination, of the sensor even at short exposures.• E ven-illumination is especially critical when taking flatfields withexposures of less than a second or even several seconds.• V ery common when taking sky flats.• S uperior two-stage cooling to -55C below ambient with air only. Its also water cooling-ready for additional cooling without having to buy a replacement back plate or other additional accessory. Its ready to go out of the box.• A multitude of advanced features such as built-in frost detection, RBI pre-flash, power management system,ethernet and USB 2.0, high accuracy temperature control,sapphire window, and user selectable internal image processing put this camera in a league of its own. No other astro camera has these features, at any price.The STT uses the same efficient pin fin heat sink design as the STX series cameras to achieve the most efficient use of space and weight while maximizing the cooling capability of the camera. This type of heat sink is more expensive than typical parallel fin heat sinks, but the results speak for themselves. The STT prototypes achieved an average temperature delta greater than -50C in 5 minutes and a max of -57C in less than ten.Twilight Flat from Iris / Leaf shutterInternal Image ProcessingSBIG’s new STT-8300, the first high speed 8300 camera with user-selectable automatic image processing! These 30 second dark frames were taken at room temperature to accentuate the number of warm pixels. The first frame is unprocessed, the second frame has a medium filter, and the third frame the most aggressive filter.Each shows fewer bright pixels and each has correspondingly lower noise in the image. The user can select from eight levels of filter strength to suit his needs.Twilight Flat from SBIG Even-Illumination ShutterThe Filter WheelSelf-Guiding Up Front : Self-Guiding in Front of the FiltersSelf-guiding has long beenacknowledged as the best, most accurate way to guide long exposure astrophotos, particularly with commercial SCTs. The single most common complaint however is finding bright stars when guiding through dark or narrowband filters. The STT filter wheel incorporates the self-guiding CCD inside the front cover of the filterwheel so that the guider picks off light from the guide stars before passing through the filters. There are two adjustment knobs on the filter wheel base: one for focus and one for moving the pick-off mirror. Problem solved!Precise Flats Solved : Micron-Precision Filter PositioningWhen taking flat field frames of filtered images, the flat field frame must show exactly the same optical characteristics to be the most effective. If there is dust on the filter, or uneven illumination caused by the filter, this must be represented precisely as seen in the lightimage to be correctedby the flat field frame.The STT filter wheel isdesigned to provide a newlevel of accuracy whentaking flats through filtersby repositioning filtersto within a few micronsevery time. This allows theimager to take extremely accurate flat field frames even after rotating the filter wheel several times, or even after a loss of power.The light frame at top left, taken with an STT and the new filter wheel, shows a large opaque spot caused by debris intentionally stuck on a clear filter.The filter wheel was rotated several times, then the clear filter was re-positioned, and a flat field image was taken through the same dirty filter.The image at bottom left shows the result after applying the flat field image to the original light frame. We measured this positional accuracy to be better than 5.4 microns, or better than a single pixel using the STT-8300.STT-8300 T ypical SpecificationsCCD Kodak KAF-8300Pixel Array3326 x 2504 pixelsCCD Size17.96 x 13.52 mmT otal Pixels8.3 millionFull Well Capacity25,500 e-Dark Current0.02e-/pixel/sec at -15C Antiblooming1000XShutter Mechanical, Even-illumination Exposure0.12 to 3600 seconds, 10ms Correlated DoubleSamplingY esA/D Converter16 bitsGain0.37e-/ADURead Noise~9.3e- rmsBinning Modes1x1, 2x2, 3x3, 9x9, x nDigitization Rate10 Megapixels per secondFull Frame Download< 1 secondMax Cooling Delta-55C with air onlyT emp.
