NGC 7023 Iris Nebula

[doessordid]

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 Slice Master to NGC 7023. Imported a new list to SkySafari and it worked.
SkyObject=BeginObject
ObjectID=4,-1,-1
CatalogNumber=Iris Nebula
CatalogNumber=NGC 7023
CatalogNumber=H IV-74
CatalogNumber=Bernes 39

It looks like SkySafari 7 Pro primarily recognizes NGC 7023 for the Iris Nebula but does not identify alternative catalog names like vdB 139, H IV-74, or Bernes 39. Your solution of explicitly adding NGC 7023 under CatalogNumber seems to have resolved the issue.
To ensure compatibility, always include NGC 7023 in .skylist files when referencing the Iris Nebula, while still keeping alternative catalog names for reference.
