Corwin's Notes
=====
NGC 771 = 50 Cassiopeiae is a star. During one sweep, JH said, "I suspect
this star to be nebulous." No one since, including JH himself, has been able
to see the suspected nebulosity. JH wrote in GC, and Dreyer quoted in NGC,
"Retained in the catalogue for future occasional observation. Nothing can be
more difficult than to verify or disprove the nebulosity of a considerable
star under ordinary atmospheric conditions."
A quick look (via SIMBAD) at the astrophysical literature on 50 Cas turned up
no observed spectral peculiarities associated with it -- it is a normal A1 V
main sequence star. Similarly, a look at the POSS1 reveals no trace of even
faint nebulosity around the star. JH may have been misled by a moment of
particularly poor seeing.
