One of the first images taken with
autoguiding - there is a slight ovalling of stars in RA due to mount
excursions. However a very transparent night! The dim halo
around the galaxy is visible - notice the edge-on background galaxy on the
left edge of M96, as well as other background galaxies (all the PGC galaxies
on my chart are visible in this image, and then some). With reference
to USNO-B faintest star visible is about 18.3 mag.
