[BAA Comets] Project Alcock website update

[Roger Dymock]

Good afternoon all,

I have made a small change to the CCD Astrometry and Photometry procedure based on a recommendation
by Richard Miles. 

The Aperture Radius in the Astrometrica config file under the Program tab should be set to an
equivalent of 5.5 arcsecs (or as near as possible). In the case of the SSON telescope the pixel size
(2x2 binned) is 0.8 arcsecs and therefore the Aperture Radius should be set to 7 pixels.

Regards
