Note: the experimental setup is improved for QSI 532 model measure (the light source is a white LED + a very stable power supply) in comparison to the QSI 583 model very noisy measure (the light source is a simple halogen lamp).

An analysis of bias frames, read noise, dark signal, photon transfer, flat fields, residual bulk image (RBI) and linearity for the QSI 532 using the KAF-3200ME CCD chip

The QSI 532ws camera mounted on a Celestron C5 Schmidt-Cassegrain provides a long focal length (1250mm) imaging setup that uses only one counter weight on the Sirius mount. Also, this configuration does not use an UV/IR cut-off filter.

The QSI 532ws-M1 CCD camera is a cooled camera used for astrophotography and scientific imaging. The photo shows the QSI 532ws-M1 camera mounted on a Tele Vue NP127is APO telescope and Astro-Physics 1200GTO German Equatorial mount.

Each pair of light frames is made for the same exposure time, but the exposure time is varied from pair to pair. The signal level and noise are determined for each pair of exposures and the noise is plotted against the signal on logarithmic axes.

The QSI 532 analysis pages discuss in detail the performance of a QSI 532ws CCD camera employing the Kodak KAF-3200ME chip, including bias frames, dark signal, transfer curves, flat fields, residual bulk image and linearity.

The QSI 532ws-M1 CCD camera is a cooled camera used for astrophotography and scientific imaging. The above photo shows the QSI 532ws-M1 camera mounted on a Pentax 75mm SDHF APO telescope. The FOV is 101.5 x 68.4 arcmin at 2.79 arcsec/pix. The QSI 532ws-M1 CCD camera comes standard with a 2 inch Nosepiece.

Feb 13, 2008 · Anyway, in the current issue of Astronomy Technology Today (which, if you don't subscribe, you should), Richard Berry reviews the QSI 532ws camera with the Astronomik-equipped filter wheel. In short, the review is very thorough - and favorable - from one of the more demanding imagers out there.

The QSI 532 Cooled CCD Camera from Quantum Scientific Imaging, Inc employs a 3.2 megapixel Kodak Enhanced Response full-frame CCD image sensor with microlens technology.

The 532wsg is an innovative new addition to the QSI 500 Series family of cooled CCD cameras. The "wsg" model has an internal mechanical shutter and filter wheel like the 532ws, plus it adds an integral Precision Off-Axis Guider.
