Perhaps this falls into the category of minutiae, but it's worth
mentioning, I think.

While roaming CdC in the area of Ophiuchus, I found that the
constellation Serpens is divided into two parts. When you search for
the constellations by name, CdC distinguishes the two as Serpens Caput
(to the west of Ophiuchus) and Serpens Cauda (to the east of
Opihuchus). However, browsing objects in those constalltions, I find
that the objects in S. Cauda are all listed as belonging to Serpens
Caput. For example, M5 is correctly labeled as belonging in S. Caput:

Globular Cluster
M   5            NGC 5904           
Constellation: Serpens Caput
Dimension:  19.9'x 19.9'  
Magnitude:  5.80 

...but M16 is labeled as...

Cluster and Nebula
M  16            NGC 6611           
Constellation: Serpens Caput
Dimension:   7.0'x  7.0'  
Magnitude:  6.00 

when it should be located in S. Cauda just over the border from Scutum.

Do the catalogs have an error, or is this a database error that just
picks up S. Caput (which appears first alphabetically) instead of S.
Cauda?


Just wanted to point this out,
Tony Hurtado
