Abstract : Speckle interferometry has been carried out during the last year with a charge-coupled device (CCD) imaging system. The emphasis of this project has been to minimize all systematic differences that arise between the images of stars in a binary star system and a reference calibration star in order to resolve a previously unresolved binary star system. Systematic errors have been minimized to the level of parts in 10,000 in the power spectrum of a stellar image. This was accomplished by using a 64x64 pixel area near the readout amplifier to minimize charge smearing, by stabilizing our CCD system to the level of a few parts in 100,000, and by using a prism system to compensate for atmospheric dispersion.
