Finger Lakes Instruments (CCD) Atlas Focuser

Today’s sophisticated imaging systems include color filter wheels (asymmetrical weight distribution), off-axis guiders, rotators, corrective optics, and CCD cameras. Together they present a formidable group of equipment that must be moved with micron accuracy and no image shift to achieve the finest results. The Atlas Digital Focuser is up to the task; an engineering pièce de résistance with unique solutions to achieving critical focus with heavy loads.

Tested Under Extreme Conditions

Ice crystals form on the surface of the Atlas focuser after it was removed from FLI's temperature chamber. The focuser handles operation in temperatures below -25°C thanks to a high-performance low-temperature lubricant. Special precautions are necessary for those cold nights, ice buildup must be in kept in check in order to allow the focuser parts to move freely.
