NGC7662 - The Blue Snowball

Credits: Fabian RRRR

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.

Facts about NGC7662 by Keith Turnecliff

NGC 7662 has an extraordinary range of brightness, making it difficult to capture all aspects of the nebula.
The inner core is quite bright and is easy to see in amateur telescopes.
However, the bright core is surrounded by an extremely faint halo and an even fainter jet.
