RX Andromedae is almost 1st magnitude!

[PMSchu]

I see the SN at the position of the Crab Nebula on 4 Jan 1055, but ST4v (4.0j) identifies the object as the Cone Nebula. The incorrect ID only occurs at a 60° zoom level or higher. At zooms of 30° or below the Crab Pulsar is identified. The mag of the SN isn't provided.

What am I missing?
