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
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.
