Camera and the Telescope
The camera needs some optical system to capture real images. It depends on the
telescope adapter to which telescopes (or lenses) the camera can be connected.
Small 1.25" barrel adapter can be used only on cameras with small CCDs.
Standard 2" barrel adapter is recommended if your telescope is equipped with
2" focuser – higher diameter ensures more robust connection. But the best way
to attach a camera to the telescope is threading the camera to the focuser (be it
T-thread or M44×1 Zeiss thread).

Photographic lens or some small refractor is the best optical system to start
experimenting with the camera. If you are using some bigger telescope at home
for the first experiments, make sure the telescope can be focused to relatively
nearby objects in the room.
It is better to start experimenting at night, because it is very easy to saturate the
camera at daylight. The shortest exposure can be around 0.2 s, which can be too
long at daylight conditions.
The following chapters provide only a brief description of G2 CCD camera
operation under SIMS (Simple Image Manipulation System) program, supplied
with the camera. Refer to the SIMS User's Guide (click “Help” and “Contents”
from the SIMS main menu) for thorough description of all SIMS features.
Temperature Control
Active chip cooling is one of the basic features of scientific CCD cameras
