NGC 7662 is a remarkable little planetary nebula in Andromeda. Visually, it appears as a beautiful blue spot, easily visible even in my little ETX-60 as an out of focus star. Photographically, it shows a sharply defined shell with a ring circling the central star. The shell also shows hints of fine detail. The central star is rather unusual for a planetary in that it is a variable star that ranges from Mv 12 to 16.
