NGC 1579 Emission Nebula

aka "Trifid of the North"





NGC 1579 (Trifid of the North) resembles the better known Trifid Nebula, but lies much farther north in the constellation Perseus. Like the Trifid, NGC 1579 is a dusty star forming region providing contrasting emission and reflection nebulae in the same field. Dark dust lanes are prominent in the nebula's central regions.

Beside NGC 1579 a second reflection nebula is visible: IC 2067 = CED 36 (small blue reflection nebula north of NGC 1579). The dark nebula is LDN1482.

  • Comments:  Although I seemed to capture plenty of sub-exposures, excessive light-pollution made it difficult to separate the signal from the noise. I may try to reprocess this image once better processing skills are learned.
