Introduction
Thank you for choosing the Moravian Instruments CCD camera. G3 and G4 
series of CCD cameras were developed for imaging under extremely low-
light conditions in astronomy, microscopy and similar areas. Design of this 
series inherits from G2 cameras, with which they share precise electronics 
providing uniform frames without artifacts and extremely low read noise 
limited only by CCD detector itself. Also the robust construction, rich 
software support and easy manipulation are the same. However, G3 and G4 
CCD camera head is large enough to contain detector up to 24×36 mm for 
G3 series and 37×37 mm for G4 series.
G3 cameras can contain also filter wheel with 5 positions for 2 inch 
(50 mm) diameter filters. Internal filter wheel is not available for G4 
cameras, because a filter wheel capable to carry 50×50 mm square filters is 
too big.
External Filter wheels with 5 positions for 50×50 mm square filters or 
7 positions for 2 inch (50 mm) diameter filters are available for G4 cameras.
Also G3 cameras can be equipped with external filter wheel, but it is not 
possible to combine internal and external wheels on single camera. G3 
camera mus be made without internal filter wheel to be compatible with 
external filter wheels.
Please note the G3 and G4 CCD cameras are designed to work in 
cooperation with a host Personal Computer (PC). As opposite to digital still 
cameras, which are operated independently on the computer, the scientific 
slow-scan, cooled cameras usually require computer for operation control, 
image download, processing and storage etc. To operate the camera, you 
need a computer which:
1. Is compatible with a PC standard.
2. Runs a modern 32 or 64-bit Windows operating system.
Drivers for 32-bit and 64-bit Linux systems are also provided, but 
camera control and image processing software, supplied with the 
camera, requires Windows operating system.
3. Provides at last one free USB port.
