OpticStar SL-131C 1/3" Color Planetary Video Camera
The SL-131C COOLAIR is a high-resolution 1.3 mega-pixel colour camera that can be used to capture images of the Sun and Moon. The camera is very easy to use and provides a quality, low noise affordable solution for viewing or capturing digital video from the telescope and recording it to your computer at a maximum 1.3 mega-pixel resolution. It is ideal for newcomers to astronomy who wish to capture high resolution images of bright objects such as the planets, Moon and the Sun (with a solar scope or suitable filters).
The SL-131C does not incorporate an infra-red block filter but can be fitted as an optional extra. The camera will operate at a maximum true resolution of 1280x1024 but lower resolutions of 640x480 and 320x240 are also supported. The camera is cased in a robust metal body and can be connected to any telescope with a standard 1.25" drawtube. Additionally, the SL-131C has a 0.25" photographic thread that enables it to be attached to a photographic tripod. A PC with a USB2.0 port running Microsoft Windows (64-bit or 32-bit) XP/Vista/7 is required.
The camera is recommended for lunar and solar (with a solar filter) imaging. It includes Opticstar View software for image capture and camera control with a point and click interface. It can capture single frames, a series of single frames in BMP format or in AVI video format. The captured video data can optionally be compressed if required in MPEG-4 format.
The SL-131C camera can stream and store video to disk at up to 15 frames per second at 1280x1024 resolution, it can also grab single frames at 1280x1024. All video and single frames are captured without compression, ensuring high image quality. Higher frame rates can be achieved by reducing the resolution via the camera control software.

Product QuestionsWhat is the highest magnitude object that can be imaged with this camera. I.E., i am considering using this camera for "lucky imaging" of bright double stars, down to magnitude of about 10. Possible?Question by: SteveMcG on Apr 18, 2014 12:34:30 PMThe answer is highly dependent on the aperture of the telescope used and the exposures used for the lucky imaging. Stars are effectively point sources of light in amateur telescopes, so aperture is very important in determining whether stars can be imaged or not in a given time period. Exposure also matters, as the longer the exposure, the fainter the magnitude of stars could be reached. For the old SBIG ST-7, the formula was an 8" f/10 scope under dark skies would get about mag. 14 in one second and about mag. 17-18 in one minute at minimum SNR (around 3:1 to 5:1). This camera is much less sensitive than the ST-7 with 50% QE instead of 80% and 5.2 micron pixels instead of 9 micron. coupled with an approximate 4x signal loss due to the Bayer matrix, you would have an equivalent sensitivity around 30x less than an ST-7, or a difference of 3.7 magnitudes. That means it would take approximately 1 second to get enough SNR for a measurement on a magnitude 10.3 star with this camera and an 8" f/10 scope. Light pollution, transparency, humidity, focus, and tracking accuracy all have profound effects, so take that as a lower limit on needed exposure. 2-3 seconds might be more realistic for a minimum exposure time per frame. A larger scope would shorten the needed time.Answer by: Chris (Admin) on Apr 21, 2014 5:49:29 AM
