Kim,
Knowing
Wolfgang Steinicke for having exchanged a few e-mails
with him about his database, I would say he will be more than happy to give you
more information about NGC2313 being a dark nebula or whatever it is…
His
e-mail address is steinicke-zehnle@t-online.de
I
still maintain there IS a dark nebula around the bright object, it just isn’t
very conspicuous, but it sure is there…

Nice one Owen, thanks
for helping to clear that up, I had not realised that Harold's positions were JD1950, it becomes clear that
they were at least talking about the same thing
at any rate, you conclusion that Wolgang has made an erroneous
description seems correct as well,
interesting that they both use DN but to mean different things though.
On thing
for certain, I will be trying hard to get a look at it later
in the year!!

I think
that Wolfgang has his description
wrong. The object is described
in the NGC as F,vS,R i.e. Faint, very small
and Round which would fit the appearance of the bipolar nebula. It was discovered
by D'Arrest probably using an 11" refractor. There is a dark
nebula from Lynds catalogue nearby but that would not fit the initial description.

You're sharper than
I am Pierre! I was so intent on looking
at the descriptions I never even noticed
that Corwin and Steinicke had
different Co-ordinates for the same object,
in fact Corwin's position is
nearly half a degree west of Steinicke's and the DSS image for that position shows only a small asterism, there is no apparent darkening of the background at all.
Steinicke however
has the bright nebulas position, but describes it as dark.
The plot thickens!!
Either that or I
have missed something fundamental here.

Kim,
Checking the Digitized Sky Survey for both positions reveals the same object
as in the picture you gave the URL to in your first message for
Steinicke’s position, and mysteriously
nothing definite for
Corwin’s position, though there
might be a background dark nebula, my
laptop’s screen not showing it really
much, maybe it’s better on a “real” screen…
Still the same laptop does show some (faint but definite) dark nebula at and
around Steinicke’s position. Steinicke quotes LDN 1653, which is a large object… Use a large field of view to see it. I used 30 arcmins:
