NGC 7023 Iris Nebula

[exceedsparkles]

Iris Nebula is missing catalog number NGC 7023.
.skylist  file
SkyObject=BeginObject
ObjectID=4,-1,-1
CatalogNumber=Iris Nebula
CatalogNumber=vdB 139
CatalogNumber=H IV-74
CatalogNumber=Bernes 39
Importing .skylist file to SkySafari 7 pro does not recognize   vdB 139,  H IV-74 or  Bernes 39. 
SkySafari does find NGC 7023. 

I changed CatalogNumber to NGC 7023. Imported a new list to SkySafari and it worked.

Good catch! Yeah, SkySafari tends to rely primarily on the NGC/IC catalog numbers for object recognition. Even though vdB 139, H IV-74, and Bernes 39 are valid alternate catalog names, they often aren’t indexed the same way in the app.
Replacing one of the CatalogNumber entries with NGC 7023 is definitely the right move—once it's in there, SkySafari picks it up without issue. I’ve run into similar quirks before with objects that have multiple designations.
