I found a cluster-like object around HR6692 (HIP 88012) in Sgr when I was making a DSO hunting plan. However it doesnot get any DSO label. The cluster-like object looks like below. The star catalog for Stellarium is "Star catalogues, v2.0" (extended data).

The object looks like Jewel Box and NGC3293 in FOV = 0.29°.

As I removed "Star catalogues, v2.0", the same field looks like below. The same confuse may not exist in Standard Version of Stellarium.

I checked same filed in Sky Safari and did not found the same struct.

The size of the "cluster-like object" is 0°2'30''. I searched in SIMBAD, and got the result ranked as Mag V as below.

Seems like catalog makers can get confused in dense star fields. You can always switch on DSS to check for real DSOs.

DSS shows the single star in a dense field. Simbad has no cluster. Again a few stars too many in the catalogs.
