  The technique of Blind Iterative De-convolution (BID) was used to remove the
atmospherically induced point spread function (PSF) from short exposure images
of two binary stars, HR 5138 and HR 5747 obtained at the cassegrain focus of
the 2.34 meter Vainu Bappu Telescope(VBT), situated at Vainu Bappu Observatory
(VBO), Kavalur. The position angles and separations of the binary components
were seen to be consistent with results of the auto-correlation technique,
while the Fourier phases of the reconstructed images were consistent with
published observations of the binary orbits.
