I want to point out that there is a longstanding issue in the Find object tool that is leaving out some objects that do exist in the database catalogues. In this example I show the incomplete list of Hickson galaxy groups in the Find tool. Then I pull up the database and open details of a couple examples that were not coming up (Hickson 90, 68). Upon doing so, the selected objects will appear in the Find tool. So it appears KStars is not loading all the database information itself. This issue likely also affects other catalogues, but I haven't looked at them as closely.
Thank you
