Constellation - Orion
Bright nebula
Distance - 1500Ly
Mag 3.7

Date - 10/12/12
Seeing - Antoniadi II
Transparency - Average
SQM - 21.63 (LM 6.4)

Telescope - 16" f/4.5
EP - 17.3mm Delos x109 TFoV 0.39˚

Sketch notes
Looked amazing in my new 16" with lots of detail in the gas clouds in M42.
I tried UHC and OIII filters but preferred the unfiltered view as I found the filters too agresive on the fainter parts of the nebulosity and generally didnt really improve the view.
I used the 17.3mm Delos as it filled the FoV and showed more detail than my low power Nagler.
