Planetary Nebula Vyssotsky 2-2
This is one of three planetary nebulae discovered in November 1945 by the Russian-American astronomer Alexander N. Vyssotsky during a survey of camera plates taken at the Leander McCormick Observatory at the University of Virginia, USA.  As this PN is the second listed object in Vyssotsky's second publication, it is referred to as Vy 2-2.
Vy 2-2 is a proto-planetary or very young planetary nebula. The kinematic age, derived from the angular expansion, is estimated to 213 ± 26 yr. The PN shows OH maser emission lines and has an angular diameter of only 0.4 arcsec. The central star may be of type Of. [616, 617] The distance is extimated to 4.394 kpc. Apparent magnitudes of the nebula through different filters: B 14.02, V 12.65, R 13.38, J 10.844, H 10.62, K 9.69.

The planetary nebula Vy 2-2 is located in the northern part of constellation Aquila. You'll find it on the longer, eastern edge of a conspicuous triangle of 6 to 8 mag stars, where the southernmost corner is formed by the double star BD +09°4085 (components HD 182219 and HD 182220, separated by 8.7"). The best time for observation is in the months from July to September.
