I'm not sure I'm submitting this to the right place, but I believe I have found a catalog error in SkySafari Pro v6.
The description of the galaxy NGC 5173 in Canes Venatici describes it as the "Southern Integral Sign Galaxy."
This cannot be correct, since (a) this galaxy is in the northern hemisphere and (b) it looks nothing like an integral sign (it's a roughly round galaxy).
However, the "Southern Integral Sign Galaxy" appears to be IC 5173 in Indus.
So it appears the catalog descriptions for IC 5173 and NGC 5173 have been mixed up.
