Object: 20 Trifid Nebula
Location: Mt. Nerone
Date 3rd Aug 2013
Pencil on white paper
This nebula is quite low at my latitude and thus is always submerged in the light pollution halo from cities in the south. This makes it a quite difficult object without a nebula filter. I have obtained the best results with an UHC-S filter. I also tried with an OIII filters which gives outstanding constrast on Lagoon Nebula, which is just nearby, but it is not the best for the trifid.
