CCD Video Photography and Analysis of Comet Schwassman-Wachman 73P Fragments B & C Using the Low-Cost Meade DSI Camera
Abstract
Near Earth Object Comet Schwassman-Wachman 73P had its closed approach to Earth on May 12, 2006. 874 8-second CCD exposures were collected for fragment B using the un-cooled low-cost Meade DSI Camera Model 1. These images have been extensively processed and made into a dramatic video that captures over 2 hour's movement of the comet through a star field. This paper discusses image processing techniques such as image registration, automatic flat fielding, image restoration and estimation of the comet's position using tracking algorithms.
