Guide Acquire Module

DFM Engineering has made many Guide-Acquire-Modules (GAMs) for Cassegrain telescopes. These modules provide autoguiding and star centering functions.

• Provides instrument common functions of acquisition and guiding
• Integrated and standardized controls for all instruments
• Mounts to standard instrument bolt patterns
• Provides standard bolt patterns for instruments
• Allows multiple instruments to be mounted to the standard telescope
• Up to 5 instruments may be mounted: N, S, E, W, and straight through
• Supports photometers, spectrographs, and direct imaging cameras
• Translating, rotating diagonal mirror
• Four position Multiport instrument selector diagonal mirror
• May be used with eyepiece, CCD camera, or autoguider
• Direct imaging filter wheel for 2-inch square filters
• Allows guiding from spectrograph slit jaws and decker
• Projects comparison lamps into spectrograph at telescope F ratio
• Position of probe displayed on telescope control system display
• Illuminated reticle eyepiece
• Usually these GAMs include a X-Y stage for off axis guiding. 
• X-Y stage with probe for guide-acquire camera or eyepiece
• Controllers configured to operate GAM, spectrograph, or photometer
• Motors only powered when moving for minimum heat generation
• Control system can control up to 11 motors
• RS 232 serial control from DFM telescope control system
• Full computer remote control from warm room
