Astrometric and photometric precision of measurements at digital processing of tv wide-angle images of astronomical objects
The analysis of methods of astrometric and photometric processing of star images at TV observations with wide-angle lenses is carried out. Classic methods which are used at CCD-images processing and use fits of star image shapes and also non-standard methods, which include both fits of non-symmetric...

| description | The analysis of methods of astrometric and photometric processing of star images at TV observations with wide-angle lenses is carried out. Classic methods which are used at CCD-images processing and use fits of star image shapes and also non-standard methods, which include both fits of non-symmetric contours of star-like objects by functions and non-fit methods are considered. Iteration methods of star image and background separation in local place of a frame are examined. The investigation was carried out for TV tube of izokon type, photographic lenses Jupiter–3 and Helios–40, videotape recorders of VHS and Super-VHS types. |
