This image consists of 28 4-minute exposures (dark master subtracted) taken on July 13th and 14th in Abbotsford.
The Trifid nebula is an active stellar nursery located in Sagittarius just above the Lagoon nebula. It derives its name from its three-lobed appearance. The red regions - emissions from excited hydrogen - are separated by dark dust lanes which block the light in the visible range. Just above the red lobes there is a faint blue region which is caused by star light reflected from clouds of dust. Its distance is estimated at 5,200 ly.
The Spitzer Space Telescope discovered 30 embryonic stars and 120 newborn stars not seen in visible light images.
