[BAA Comets] Project Alcock website - new tutorial

Thu Apr 10 16:58:03 BST 2014

Good afternoon all,

I have added a new tutorial, Astrometry and Photometry of CCD images using Iris, to the website.

If anyone can tell me how to 'remove' stars from the coma of a comet it would be appreciated. If
that person is going to be at the Winchester Weekend perhaps they could enlighten me then.

Regards
