Hi Godina
I have the original Orion Deep Sky Star Shooter (ODSSS) which has Peltier cooling and I use it as a guide camera with a WO 66mm ‘scope as the separate guide scope.
It came with MaximDL Essentials, an application that I didn’t like, so I use PHDGuiding instead, which I do like. The original ODSSS is a colour CCD and is cooled (via a separate mains adapter) so I don’t get any noise in the 640x480 frame when auto guiding, so the stars are always nice and clean. I generally use exposures of between 2 and 10 seconds to find suitable guide stars.
Just from a casual observation, it seems to guide as well as the separate guide chip on my SBIG ST7 CCD camera in terms of producing round stars in the imaging camera.
Cheers
Dennis
