SBIG ST-9XE CCD Imaging Camera System Class 1

 

The ST-9XE is identical to the ST-8XE cameras with the exception of the imaging CCD. The ST-9XE utilizes the same patented dual sensor head design integrating one CCD for self-guiding and another CCD for imaging. In the case of the ST-9XE the imaging sensor is the new Enhanced KAF-0261E detector from Kodak with 512 x 512 pixels at 20 microns square. The ST-9XE Imaging Camera is ideal for use on long focal length scopes where a larger field of view than an ST-7XE is desired, but one's budget does not allow for an ST-8XE camera. Large scopes, even those with relatively fast f/ratios, have focal lengths that "waste" sensitivity of cameras using detectors with small pixels. Longer focal lengths also mean smaller fields of view given a fixed detector size. Take, for example, a C-14 at f/7, 16" SCT at f/6.3 and a 20" f/5. In all of these cases the telescopes have focal lengths of about 98 to 100 inches. When used at 100 inches of focal length, the 9 micron pixels of the ST-7XE and ST-8XE cameras subtend about 0.7 arcseconds - a bit small for this focal length under average seeing conditions. So these cameras are often operated binned 2x2 at focal lengths of 100 inches or more unless the optics and seeing are rather exceptional. For the ST-8XE this is no problem because the detector has 1.5 million pixels and binning 2x2 still leaves the user with a reasonable 765 x 510 pixels @ 18 microns. But binning the ST-7XE 2x2 yields an image that is 382 x 255 so the image size on the monitor begins to get small for this size camera. However, the ST-9XE's 20 micron pixels subtend about 1.6 arcseconds per pixel at 100 inches focal length without binning. Just about perfect for optimum sensitivity under typical seeing conditions. This gives the long focal length user the advantage of larger more sensitive pixels and a reasonably large image of 512 x 512 at a substantial savings compared to an ST-8XE. Moreover, the FOV of the ST-9XE is nearly as large as an ST-8XE.



Sensitivity

With its relatively large (20 micron) pixels, the ST-9XE is approximately 20 times as sensitive as a standard ST-7XE ABG camera (binned 1x1) with a field of view approximately 3.3x as large as the ST-7XE. This compares very favorably with an ST-8XE operating in 2x2 binned mode at about half the cost of the ST-8XE. So for long focal lengths where one cannot take advantage of the smaller pixels of the ST-7XE or ST-8XE, the ST-9XE is an excellent choice.

The ST-9XE is an excellent choice for minor planet and supernova searches when one's budget does not allow for a very large CCD camera such as the KAF-1001E based ST-1001E camera. Moreover, the ST-9XE is capable of self-guiding with a built-in TC237 tracking CCD. It is therefore capable of hour long self-guided exposures for deep space imaging. The ST-9XE accepts all of the same accessories as the ST-7XE and ST-8XE cameras including the integrated CFW8A color filter wheel for color imaging or UBVRI photometric measurements, AO-7 adaptive optics device, CLA7 camera lens adapter, etc.
