Useful information:
HD 93308, or HR 4210 [aka Eta Car]*
Coordinates*
10h45m
-59'42"
*Simbad Astronomical Database

Eta Car is currently a 7th magnitude star, but its is a variable.
Its mass is ~ 150 Msun.*
Its Luminocity is ~ 6x10^6 Lsun*
*pg. 528 "An Intro. to Modern Astrophys.", Carroll and Ostlie 1996

The long axis of the Homunculus is 16", which at the distance of about 2.3kpc corresponds to roughly 19000 AU. The mini Homunculus is 1.5" in radius or about 3840AU in radius.*

The radius of eta car is something of a mystery as we can not directly see the star. But most Luminous Blue Variables have Radii between 300-500 Rsun.
