Primary ID vs Alternate ID populated in the log

There are often more than just two IDs for an object. To determine which is the primary and which is the secondary, SkyTools uses a designation hierarchy. Some types of designations are considered more common, such as a Messier number, so they are used as the primary ID. The next most common designation (say, NGC) is the secondary ID. You are seeing some objects with common names instead of Messier, because common names are at the top of the designation hierarchy. If an object has a common name, this will be the primary ID.

Now that you know how it works, I can tell you that you have control over this hierarchy. If you don't ever want to see a common name, you can turn them off. Or set things up so that the Messier is always the primary ID (if there is one). To do this, open the SkyTools Preferences dialog from the button on the planner tool bar. Select the Designations tab. For more information click the help button on the dialog.

This is one of the many features that makes SkyTools much more customizable that other software.
Clear skies,
