The innovative OAG-8300 turns any ST-8300 or new STF-8300 into a self-guiding camera system.
The OAG-8300 is designed to work with either the 5-position or 8-position filter wheel. Color cameras, or mono cameras without a filter can also
use the OAG-8300 with a spacer.
What is unique about the OAG-8300 is the 7-element internal optical design. The OAG ontains relay optics that move the guide camera to the side of the imaging camera, and at the same time, a 0.7X reducer effectively doubles the field of view of
the guider. This design allows for a low profile between the camera and the telescope, reducing backfocus requirements, and at the same time, gives a wide field of view that offers more guide stars for the guide camera.
The STF-8300 is the second generation 8300 camera from SBIG in the same body as the popular ST-8300. Physically, the STF-8300 looks identical to the ST-8300 model, with the exception of a desiccant plug on the side of the camera opposite the connectors.
However the STF model has new, faster, lectronics, a full frame buffer, a user rechargeable desiccant plug and automatic image processing. A full frame, high-resolution image will download in less than 1 second. The camera is also available bundled in several of the most popular Configurations with a 5-position or 8-position filter wheel, off-axis guider, ST-i autoguider, and filters.
Special Packages Include:
I. OAG Package includes the camera, FW5 filter wheel, off-axis guider and custom Pelican Case
II. Self-Guiding Package includes the OAG package plus the ST-i Autoguider
III. The Pro Package includes the Self-Guiding package plus a set of Baader 36mm LRGB and H-alpha filters.

The new mid-sized STT Series cameras offer features and specifications found in no other astrocamera – of any size. Drawing on all of SBIG's previous experience and the best of each of their 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.
Check out the following features
• Camera, Autoguider, and Filter Wheel now fully integrated with tracking sensor in front
of filters. No separate guider required!
• New Micron-Precision filter wheel provides unmatched flat field accuracy for high end
imaging and high precision photometry
• Lightning fast downloads < 1 second full-frame
• Superior two-stage cooling to -55 deg C ambient with air only
• Built-in frost detection
• User Selectable Internal Image Processing
• USB 2.0 and Ethernet connectivity for remote observatories
• Superior 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.

Internal Image Processing
SBIG’s new STT-8300, the first high speed 8300 camera with user-selectable automatic image processing!
• Since its founding, SBIG’s
mechanical shutters have been designed for
highly reliable, evenillumination, of the sensor
even at short exposures.
• Even-illumination is especially critical when
taking flatfields with exposures of less than a second or even several seconds.
• Very common when taking sky flats.
The Filter Wheel
Self-Guiding Up Front: Self-Guiding in Front of the Filters
Self-guiding has long been acknowledged 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 selfguiding CCD inside the front cover of the filter
wheel 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

A new filter wheel design for the STT series sets it apart from other designs. The carousel holds eight 36mm filters and inserts are available for 1.25" and 31mm filters. An optional filter wheel cover is available for wide angle imaging with Nikon or Canon 35mm camera lenses, or for anyone who does not need or want the built-in self-guiding feature.
The second unique feature of the STT filter wheel is a positive centering mechanism that precisely re-positions and firmly holds filters in the same position over the CCD no matter how many times the carousel is moved. In our tests of the new design, the re-positioning of filters was accurate to better than one pixel (5.4 microns) using an STT-8300 after several complete rotations of the filter carousel. This degree of precision means that flat fields taken after the filter has moved and returned are accurate virtually to the level of a single pixel.
The new Canon EOS lens adapter for the ST-8300 is designed to fit the camera with or without an FW5-8300 or FW8-8300 filter wheel. A spacer is used in place of the filter wheel to maintain the correct distance for achieving infinity focus. The production adapter is black anodized, except the center ring.
In order to provide even more functionality for the popular ST-i camera, SBIG has developed a Guiding Kit made specifically for the ST-i that turns the small camera into a complete guiding system.
The kit consists of a custom c-mount adapter, a high quality 100mm FL f/2.8 lens with lens hood, rock-solid mounting rings and a universal mounting plate for attachment to virtually any telescope equipped with a piggyback mount or accessory plate that uses a standard 1/4-20 bolt or threaded hole.
The assembled system is ultra-compact, only 6.5 inches long, and weighs less than 13 ounces (368 grams), including the camera!
Even so, it is capable of guiding to sub-arcsecond accuracy on stars fainter than 7th magnitude using 1-second exposures. With its 2.7 x 2.0 degree field of view, this means that there will virtually always be a suitable guide star in the field of view no matter where the telescope is pointed in the sky.
The benefits of this are twofold: first, there is no need to hunt for guide stars, and second, since there is no need to adjust the pointing of the guide scope to find suitable guide stars, the guider can be more firmly mounted to avoid differential deflection.
Unlike mounting systems using rings with three point adjustment screws that can move or flex, the oversized rings of this Guiding Kit clamp firmly around the body of the ST-i camera and hold it firmly in place. Guide scopes that use adjustable mounting systems are almost always plagued with differential deflection. The ST-i guiding Kit is mechanically rock-solid.
In addition to making guiding a complete and easy task, this kit also makes the ST-i a very capable electronic finder scope. The ST-i, with its built-in shutter can take dark frames allowing the useful capture of relatively long exposures compared to other guiders. The lens of our new Guider Kit has a fast focal ratio of F/2.8.
Combined with the sensitivity and dark frame capability of the ST-i means that globular clusters and cores of galaxies are within easy reach of this compact system. In tests of the ST-i and Guider Kit from a typical backyard observatory with average light pollution, stars dimmer than 10th magnitude were detected in 1-second exposures. In 10 seconds, stars dimmer than 13th magnitude were recorded and stars as dim as 15th magnitude were captured in 30 seconds.
The innovative, eyepiece-size ST-i camera is aimed at both entry level and advanced amateur
astronomers. Unlike other autoguiding cameras, the ST-i includes a mechanical shutter, providing
greater sensitivity and more accurate guiding as users can now automatically capture and use dark
frames while autoguiding.
The camera can take exposures as short as 0.001 seconds and focus at up to 21 frames per second. It will download 16-bit images at up to 12 frames per second, allowing users to extract finer detail with higher dynamic range than 8 bit cameras, especially when doing planetary imaging.
SBIG pioneered autoguiding by introducing their first ST-4 autoguider in 1989. Continuing the SBIG tradition of providing complete high quality solutions, the ST-i comes with fully functional versions of Software Bisque’s The Sky version 5 and CCDSoftV5,. Combined with SBIG’s own CCDOps
TM and PlanetMaster TM software for high-resolution planetary imaging, this imaging software suite provides customers with a powerful and comprehensive set of tools. The imaging software suite not only supports the planetary imaging and autoguiding functionality of the ST-i but also includes a full featured planetarium program with telescope control for most commercial telescopes. These are extremely desirable features for users of DSLR’s and other astronomical imaging cameras.
If purchased separately, customers would pay a significant percentage of the price of the ST-i and
imaging software suite just for similar software alone.
