About this work
False-color composite of the Orion–Eridanus Superbubble from data of the Northern Sky Narrowband Survey. Ionized hydrogen (Hα at 656.3 nm, without continuum) is mapped to red, blue continuum (including some [OIII] and Hβ emissions) is mapped to green, and red continuum (without Hα but with some [SII] emissions) is mapped to blue. Emission nebulae are reddish while reflection nebulae are green to blue. Stars are partially subtracted in order to make the faint nebulae visible.
The field of view is 50° × 39°. Equatorial center coordinates are RA=4h36m and DEC=3°. North is up.
