Summary0001267: Suggestions for deep sky labels
DescriptionJust two suggestions for the labels of deep sky objects. This is just my opinion; you or other users might have different views.

1. For NGC objects, remove the prefix NGC and leave just the number. For example, NGC 1234 becomes just 1234. This would reduce clutter on the chart. All printed sky atlases I know show NGC objects without the prefix.

2. Make the font used for the labels of deep sky objects the same size. Now, smaller objects have smaller font labels, larger objects have labels with larger font (see attached image). Since I am able to choose the font size for deep sky labels, I think that the labels should stick to the font size I have chosen. Again, all printed sky atlases use consistent font sizes for deep sky labels.

Ad. 1. It's good idea.
NGC 1234 => 1234
IC 567 => I567
PGC 12345 => P12345
UGC 1234 => 1234
etc.

Ad. 2. Modern atlases use variable font size and/or weight:

No.1 Disagree
Stick to the Vizier standard acronyms for labelling dso's unless absolutely necessary as it complicates searches and filters - users will get into the habit of thinking that 'N', 'U' etc are valid catalogue acronyms.

That said, there is also an informal convention (in Webb Society Guidebooks) to prefix common catalogs with a single letter, M=Messier, N=NGC, I=IC, UGC=UGC, P=PGC, H=Hickson. Thus labels would then for example be: M107 and N1234, I567, P12345,U1234 and H67/H67b. This is better than the suggested alternative which drops the source catalogue letter entirely.

No.2 Agreed, sounds OK.

regards
Peter
