My skies never approach an l.m. of 7.3 the six mark is typical. I think the
secret was to follow the line of stars to locate it. The picture in the book
was a definite help as I knew exactly where to look. It is a satisfying
little beast to catch. The movement effect, by the way, was very pronounced

The ISBN for the book is 0-913135-14-3. It is priced at $14-95. I bought it
from Broadhurst Clarkson in London at, as British Astronomers will guess,
It is definitely worth the money though. it is distributed in the UK by
Airlife Publishing Ltd., 101 Longden Road, Shrewsbury SY3 9EB, England.

It is a collection of Deep Sky articles. It really is a find for hunting out
odd objects. It has a whole chapter on M31 and its objects plus another on
local group galaxies. It is a pity Deep Sky ceased independent publication.
I got the positions of the M31 supergiants from there and intend to try for
some of the globulars in M31 - one day. There is a whole chapter on them.
