The 4 Megapixel STL-4020M with interline CCDs offer large imaging areas, excellent anti-blooming characteristics and high pixel density at a reasonable cost.
The built-in filter carousel accepts both 50mm unmounted round filters and filters mounted in 48mm threaded cells. Filter selection is accomplished with the camera control software. Optional LRGB and UBVRI filter sets are available from SBIG. 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.
The built-in guiding CCD is a TC-237H frame transfer device with high sensitivity and a 657x495 pixel array. The optional remote guiding head contains an identical TC-237H CCD. When the remote head is attached to the main camera the user can select either the internal or the remote guiding CCD for self-guiding a long exposure.
2. CCD for CaK Telescopes: SBIG ST-2000XM
Model ST-2000XM uses an high quality interline CCD from Kodak, the KODAK DIGITAL SCIENCE™ KAI-2001M Image Sensor Megapixel Progressive Scan Interline CCD. The KODAK DIGITAL SCIENCE™ KAI-2001M is a high-performance multi-megapixel image sensor designed for a wide range of scientific, medical imaging, and machine vision applications.

ST-2000XM CCD IMAGING CAMERA (SBIG) |
The 7.4 mm square pixels with microlenses provide high sensitivity and the large full well capacity results in high dynamic range. The vertical overflow drain structure provides antiblooming protection, and enables electronic shuttering for precise exposure control. Other features include low dark current, negligible lag and low smear.

KAI-2000M 2 Megapixel CCD (Kodak) |
The KAI-2001M CCD is a 2 megapixel progressive scan detector with an active image area of 1.92 million pixels. The active image area is 1600 x 1200 pixels. The ST-2000XM is a self-guiding camera, utilizing SBIG's patented dual sensor design. The imaging CCD is nearly the same size as the KAF-1602E used in the ST-8XE but due to the smaller pixel size it contains nearly half a million more pixels than the ST-8XE. Full frame download time is approximately 4.5 seconds with our new high speed USB electronics. This camera is also fully compatible with all of our existing accessories such as the CFW8 filter wheel and AO-7 adaptive optics device. The ST-2000XM has antiblooming protection and the quantum efficiency is comparable to the ABG versions of the new enhanced full frame "E" detectors used in the ST-7XE cameras with a shift in the peak sensitivity toward the blue. Compared to the ABG versions of the full frame "E" series cameras, the ST-2000XM is more sensitive in the blue and green, and slightly less sensitive in the red. Moreover, because the ST-2000XM has two CCDs (a guiding CCD as well as an imaging CCD) in the same camera head, it is capable of self-guiding without any compromise in the quantum efficiency of the imaging CCD. In other words, not only CAN it self-guide, it can do so without having to double the exposure time to compensate for the guiding feature.

3. Astrovid-SolarCam B&W CCD Video Imaging System
The ASTROVID SolarCam™ is a 2/3 inch monochromes video camera system especially well suited to solar imaging. The ASTROVID SolarCam™ works well for white light, H-alpha nad Calcium observing.
 |
Astrovid-SolarCam (AVA) |
The ASTROVID SolarCam™ video camera has greatly increased sensitivity to infrared radiation to approximately 1100nm. This should not be an issue with narrowband H-alpha and Calcium filters. These filters to be safe for visual use, must block out IR radiation.
For white light observations, we highly recommend the Baader Planetarium Solar Continuum Filter and also the Baader Planetarium Neutral Density filters. A Wratten green #56 or green #58 filter can also be substituted. These filters will greatly increase the contrast of fine solar surface detail.
Other filters such as the greens, blues and neutral density filter can also be used with H-alpha and Calcium Solar filters to get the light to acceptable levels to show fine solar surface structure and prominences.
The SolarCam™ has manual controls that should accommodate any solar imaging Situation including white light and narrowband. The compact size of the SolarCam™ will allow it to adapt to any size telescope.
The Astrovid SolarCam System includes, Camera Head with Sony 2/3" Chipset, 25' Shielded BNC to RCA Video Cable, Power Cable, 110 Volt Power Supply, C - 1.25 Inch Adapter, Instructions, One Year Warranty.
