Comments:  NGC 7662 (also known as the Blue Snowball Nebula, Snowball Nebula or Caldwell 22) is a planetary nebula located in the constellation Andromeda. It has a faint central star that is variable, with a magnitude range of 12 to 16. NGC 7662 is a popular planetary nebula for casual observers. A small telescope will reveal a star-like object with slight nebulosity. A 6" telescope with a magnification around 100x will reveal a slightly bluish disk, while telescopes with a primary mirror at least 16" in diameter may reveal slight color and brightness variations in the interior.
