Re: (IAAC) NGC2313 a Dark Nebula??

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:

Ciel clair / Clear skies,

Both seem to have 2313 listed as a Dark Nebula
