The Trifid Nebula

Contributor: Lucas Ferreira

Homepage: http://www.Lucastronomy.co.za

The Trifid Nebula in Sagittarius required twenty-six 30-second exposures (ISO 800) which were then processed with 14 dark and 7 bias
frames in DeepSkyStacker. Taken with an 8-inch f/5 Newtonian telescope and a Pentax K110 DSLR camera.

The pinkish rosette-like nebula, divided by tendrils of dark lanes, is the Trifid. The blue (reflection) nebula to its right (north on the sky) is visually far more challenging than the Trifid.
The complex dark nebulae are recorded as Barnard 85. A 3-inch telescope should show them, although there are reports of them being seen in 11x80 binoculars.

nothing more to see. please move along.
