oftware for the MacOSX operating system. No other manufacturer offers better software than you get with SBIG cameras. New customers receiving their CCD imaging camera should first read the installation section in their CCDOPS Operating Manual. Once you have read that section you should have no difficulty installing CCDOPS software on your hard drive, connecting the USB cable from the imaging camera to your puter, initiating the imaging camera and within minutes start taking your first CCD images. Many of our customers are amazed at how easy it is to start taking images. Additional information can be found by reading the image processing sections of the CCDOPS and CCDSoftV5 Manuals. This information allows you to progress to more advanced features such as automatic dark frame subtraction of images, focusing the imaging camera, viewing, analyzing and processing the images on the monitor, coadding images, taking automatic sequences of images, photometric and astrometric measurements, etc. A PERSONAL TOUCH FROM SBIG At SBIG we have had much success with a program in which we continually review customer39。 s images sent to us on disk or via . We can often determine the cause of a problem from actual images sent in by a user. We review the images and contact each customer personally. Images displaying poor telescope tracking, improper imaging camera focus, oversaturated images, etc., are typical initial problems. We will help you quickly learn how to improve your images. You can be assured of personal technical support when you need it. The customer support program has furnished SBIG with a large collection of remarkable images. Many customers have had their images published in SBIG catalogs, ads, and various astronomy magazines. We wele the chance to review your images and hope you will take advantage of our trained staff to help you improve your images. TRACK AND ACCUMULATE (. Patent 5,365,269) Using an innovative engineering approach SBIG developed an imaging camera function called Track amp。 Accumulate (TRACCUM) in which multiple images are automatically registered to create a single long exposure. Since the long exposure consists of short images the total bined exposure significantly improves resolution by reducing the cumulative telescope periodic error. In the TRACCUM mode each image is shifted to correct guiding errors and added to the image buffer. In this mode the telescope does not need to be adjusted. The great sensitivity of the CCD virtually guarantees that there will be a usable guide star within the field of view. This feature provides dramatic improvement in resolution by reducing the effect of periodic error and allowing unattended hour long exposures. SBIG has been granted . Patent 5,365,269 for Track amp。 Accumulate. DUAL CCD SELFGUIDING (. Patent 5,525,793) In 1994 with the introduction of Models ST7 and ST8 CCD Imaging Cameras which incorporate two separate CCD detectors, SBIG was able to acplish the goal of introducing a truly selfguided CCD imaging camera. The ability to select guide stars with a separate CCD through the full telescope aperture is equivalent to having a thermoelectrically cooled CCD autoguider in your imaging camera. This feature has been expanded to all dual sensor ST series cameras (ST7/8/9/10/2020) and all STL series cameras (STL1001/1301/4020/6303/11000).。
