Constellation In Focus: Cygnus
Constellation In Focus: Cygnus

NGC 6960 & NGC 6992, the West and East Veil Nebulas, are part of the Cygnus loop, the remains of a supernova that exploded over 100,000 years ago. Two other sections, NGC 6995 and 6979 are close by.

M29 is an unimpressive open cluster, notable only in that it was one of the original discoveries of Charles Messier.

NGC 6819 is a small open cluster with about two dozen stars from 10th to 12th magnitude within a 5? circle. Its discovery in 1784 is attributed to Caroline Herschel.

Deneb, which marks the tail of the swan, is one of the 20 brightest stars in the night sky. Just three degrees away lies NGC 7000, the North American Nebula, so-called because of its obvious shape. This is an active star forming region and quite large, though it?s difficult to see without the aid of astrophotography.

M39 is an open cluster, and is a nice binocular object with 30 or so stars spread over its seven lightyear diameter. It?s also "pretty close" to Earth, at "just" 800 lightyears.

Finally, NCG 6826, the Blinking Nebula, gets its name from an odd phenomenon: its central star appears to blink on and off when you look toward and away from it quickly.
