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,
£14-95.
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.
