Re: (IAAC) OBJECT:NGC4762(edge-on galaxy) INST: 18" f/4.2 Newt (dob)



Todd,
NGC 4762 is indeed a good edge-on spiral.  It is also one of the Herschel
400 objects.  In fact, there is a sketch of this galaxy on page 31 of the
Herschel 400 handbook.  I had a fine view of NGC 4762 on 5/24/98 UT
through a 20" f/10 classical Cassegrain.
