RE: (IAAC) NGC2313 a Dark Nebula??
Kim,
When you talk about "the new NGC/IC catalogue", what document do you
refer to exactly? (title or URL, please)
There are notably:
The Revised New General Catalogue, by Sulentic and Tifft
NGC 2000.0, by Sinnott
As for The NGC/IC Project, there are three versions of the catalogue in
there, by Corwin, Thomson and Steinicke...
So there are more than only one "new NGC/IC catalogue"...

Subject: (IAAC) NGC2313 a Dark Nebula??
Something I like to do is collect images of the NGC list, I do this via
the
DSS and then "enhance" the images in photoshop so that they have a dark
background and blue-white stars, so that to a certain extent is
replicates
the view in the eyepiece.
It was while performing this part of the hobby that I came across
NGC2313,
which is listed in the new NGC/IC catalogue as a dark nebulae, yet the
image
clearly shows something that is distinctly bright and nebulous, checking
through the observations of Steve Gottlieb that he made for the NGC/IC
project I see the object is not listed, as such I have no Idea what the
magnitude of the bright "thing" is, or even what it is, and also where
is
the dark neb? on the DSS image there was no area that looked any darker
than
any other.
This is a link to a colourized version of the DSS image, no other
adjuatments ahve been made.

Saguaro Astronomy clubs list has it as a difuse nebula.
Anyone had a look at this before?
