Humason 1-2 is a tiny, often overlooked planetary nebula in Cygnus.. At high magnification look for two opposing lobes. A six inch will show the nebula as a faint star that looks slightly non-stellar. Larger apertures and high magnifications are required for a good view.
In "Summertime Planetaries Beyond the NGC" (August 1999, Sky & Telescope) Jay McNeil describes this planetary as "Easily located just 3o east of the 4th-magnitude Sigma Cygni, Hu 1-2 appears virtually stellar at powers below 300x. However, it's identity becomes quite apparent when the field of view is blinked with a filter. Using a 10-inch telescope and magnifications approaching 400x, this object displays wonderful structure reminiscent of the Dumbbell Nebula."
