Rosetta Earth Swing-By 1 - Images

page 1, until 04 Mar - go to page 2

Introduction

On this page you'll find all images of Rosetta before 04 Mar 2005 that were sent to ESA, both from amateurs and from professionals. For the non-specialist, a short explanation of the abbreviations: SCT is a Schmidt-Cassegrain Telescope, typically produced by the companies Meade or Celestron. 12" is the aperture in inch, i.e. 30 cm. The pointing position is given in Right Ascension (R.A.) and Declination (Dec.), which are coordinates in the sky. The magnitude is given in the astronomical magnitude system - the brightest stars are around 0 mag, the human eye sees down to about 6 to 7 mag. 17 mag is quite faint...

Enjoy!
