Abstract
This paper presents an algorithm for restoring telescope images corrupted
by turbulence effects and readout noise of a telescope system in order to
determine centroid positions of stars, especially the position of a
reference star. A computation method employing an accurate centroid
estimation algorithm reconstructing a point spread function (PSF) from the
recorded astronomical images has been used. Minimisation of turbulence
effects and telescope control system noise in long exposure images
acquired and recorded by the ground telescope is proposed. As a solution
of the distortion error a minimisation signal is dedicated to GoTo
calibration procedures built in control mechanisms of the
electromechanical telescope system. The proposed method has been verified
in the Matlab environment for real deep sky images recorded by the ground
telescope system.
