24K24KThe image above will show you the LcCCD14 camera from OES with an important modification: the fan at the backside. It improves cooling significantly.
Other technical specs of the camera are:
Resolution: 772 x 580 Pixels (interlaced) 0.6 arc-seconds per pixel at the CG11 prime focus, 1.4 arc-seconds when used with my dobsonian.
772 x 290 Pixels high res. modes for planets, comets and the moon.
386 x 290 Pixels (binned by 2) more sensitivity and better matched to the long focal length of the CG11. One pixel covers 1.2 arc-seconds here.
Chipsize, fov and type: 6.4 x 4.8 mm, 7.8'x5.9' (C11), Philips FT800P, frame-transfer chip with anti-blooming
Cooling: Peltier (regulated) and fan. (In this specific camera the CCD was never cooled below -5 deg Celsius independend of the environmental temperature. This is a big problem not only in hot summer nights.)
AD-resolution: 12 Bit
Connector: Printerport of PC
Power req.: 3.5 Ampere at 5V , 0.4 Ampere at 12V.
Software: Self made
Image format: FITS !!! (float and 16 Bit). Note! You need twice as much disk space as necessary just because every stupid image processing system (IRAF included) uses it's own image format. Most of these will kill your header information in the first step. So why don't they use the well established FITS-Format for astronomical images. (Most of the programs read and write it, but still convert to the own internal format).
My images of the great comets Hyakutake and Hale-Bopp were made withe this camera, as well as some deep-sky shots.
You can update the latest OES-LcCCD14SC camera software (ZIP-File) from here.
For image processing software I should point you to IRAF
running under the control of LINUX.
