NGC 6894 is a magnitude 12.3 planetary nebula in Cygnus. NGC 6894 is sometimes called the Diamond Ring Nebula, because the 14th magnitude star on the left of the nebula gives this planetary the appearance of a diamond ring when viewed through amateur size telescopes. NGC 6894 is located a little more than 6 degrees east of the Veil Nebula. NGC 6894 is a typical planetary nebula appearing as a ring of glowing gas similar to the Ring Nebula in Lyra. This small object is only about 0.9 arc-minutes in diameter.
This image was taken using the University of Arizona Steward Observatory 61-inch Kuiper Telescope. The University of Arizona has a public outreach program at the Mt. Lemmon SkyCenter that I highly recommend. You can view and understand the night sky with an expert astronomer to guide you on an adventure under the stars. They have a RCOS 24-inch telescope dedicated to that program, and some of their astronomy camps also include opportunities to observe with the 61-inch Kuiper Telescope. The 61-inch Kuiper Telescope is located on Mt. Bigelow in Arizona at an altitude of 8230 feet. This RGB composite CCD image was taken with an FLI IMG6303e CCD.
