Description Technical Specs Extended Information
 
Delivers the absolute highest contrast views of many diffuse and planetary nebula.   For many objects, the Baader O-III reveals a level of intricate detail that rivals the best deep sky photographs.   Our favorite filter for the majority of nebula, especially The Veil, Lagoon (M8), Swan (M17), Ring (M57) and Dumbell (M29).  With a large scope, you can even view the famous 'Pillars of Creation' in M16 (Eagle).

The Baader O-III perfectly isolates the two doubly ionized oxygen lines (496 and 501nm), through a very sharp and narrow bandpass (10 nm wide!, the narrowest of any O-III filter).   Unlike other O-III filters, the Baader O-III completely blocks longer and shorter wavelengths (ever wonder why some O-III filters appear RED?, instead of the correct 500 nm Teal color).  The result is the highest contrast achievable in an O-III filter.
Features

  • --greatest contrast of all O-III filters
