I am selling my SBIG ST2000XM self-guiding monochrome CCD with the CFW8A filter wheel and 1.25" Ha, LRGB filters. It was hardly in use, and I have recently spent $500 sending it back to the USA for complete operational testing, analog board reset and desiccant recharge. I have tested it at 0 degrees Celsius in Singapore with no frosting issues. Due to the heavy light pollution in Singapore, a monochrome CCD like this will provide a gateway for narrowband imaging. Since it does not have a bayer mask, it will be able to fully utilise the full extent of the light that it collects.
Here are some images of the camera:
Here's a 6x5 min H-alpha test image of the Prawn Nebula, photographed from my home window in Toa Payoh.
Asking for $1100. Looking to sell this as I already have another SBIG CCD.
