Description

Sh2-261 Lower's Nebula is super faint. I was hoping to finish it off in the Hubble Palette, but my main Astro-Physics Mach1 mount was gone for a month for warranty repair, so I lost a lot of time. It is now dipping into the west with less than a half hour to work with each night, so had to call it here in this bicolor palette.

The HII region Sh 2-261 is often called Lower's nebula because it appears on a photographic plate taken by the father-and-son team of Harold and Charles Lower in 1939.

The Lowers were amateur astronomers, accomplished telescope makers and pioneering astrophotographers from San Diego, California. Harold Lower published a pamphlet in 1939 describing an 8 inch Schmidt camera that he and his son had constructed several years previously. He notes that the camera has been especially useful in photographing what are now called HII regions.
