Nebulae below the galactic plane

A 55°×55° view showing nebulae below the galactic plane is presented. The region includes the constellations Pisces, Pegasus, Andromeda, and Lacerta. Most of the structures are thin reflection nebulae that scatter light from the Milky Way. That is why they are referred to as Integrated Flux Nebulae.

High galactic latitude nebulae below the galactic plane in H-alpha, blue continuum and red continuum — False color composite where Hα (without continuum) is mapped to red, blue continuum (including [OIII] and Hβ emissions) is mapped to green, and red continuum (without Hα but with [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 galactic plane is parallel to the upper border of the image. The pink nebula above the image center is SH2-126, ionized by the LAC OB1 association, located 450 pc away. The emission nebula (red) near the bottom right corner is most likely ionized by π Aqr, a Be Star in a distance of about 340 pc (Gaia DR3). The galaxy near the left side of the image is the andromeda Galaxy (M31) along with its companion, M110.
