GALLERY S BL AST FROM THE PAST Harel Boren Sprawling across the northwestern corner of Vela, the Sails, are the delicate remnants of a supernova some 800 light-years away whose light reached Earth about 11,000 years ago. What a stunning sight that must have been! This view is roughly 6° wide, with east up. DETAILS: Officina Stellare Veloce RH 200 astrograph and SBIG STL-11000M CCD camera with six wide- and narrowband filters. Total exposure: 11.7 hours. W SEAGULL'S HEAD John Vermette Located 8° northeast of Sirius, van den Bergh 93 is known as the Parrot Nebula - but, confusingly, it also serves as the head of the much larger Seagull Nebula (IC 1277 or Gum 1). DETAILS: Hyperion 12.5-inch astrograph and SBIG STL-11000M CCD camera with Hα and RGB filters. Total exposure: 17.7 hours.
