Re: (IAAC) How Bright are the Galaxies - Really?
Well considering that the main function of
the revised Catalogue was to eradicate the errors in the original especially
with regard to the correct position of objects, it was an excellent inclusion
into Skymap, afterall, it would be of little use knowing exactly how bright
something was if you couldn't find it in the first place! I would imagine that
seeing faint objects with the unaided eye is affected by many variables other
than V mag anyway, not least the condition of any particular individuals eyes as
a major factor, so to write off such sightings as a non event based soley on
listed magnitudes is perhaps a bit hasty?!

Well, Chris is
correct about the CONTENT of any catalogue or database, but he
which to include in his program. Overall, the new Steinicke
to be a step in the right direction - especially as to
dimensions of the thousands of objects. The magnitude issue,
another matter. I like the dimmer "B" magnitudes, as I find them
guide to back yard visibility. However, others may feel just as
other way - and with perfectly good reasons.
