The Baader OIII Nebula Filter - 1.25-Inch by Baader Planetarium is a cutting-edge optical tool designed for astronomers seeking to enhance their viewing experience of celestial objects. This filter is renowned for its ability to deliver the highest contrast views of many diffuse and planetary nebulae, revealing intricate details that are often lost with other filters. Its exceptional performance is particularly evident in observing objects like The Veil, Lagoon (M8), Swan (M17), Ring (M57), and Dumbbell (M29), as well as the famous 'Pillars of Creation' in M16 (Eagle).

Key Features:

• Isolates the two doubly ionized oxygen lines (496 and 501nm) with an ultra-narrow bandpass (8.2nm wide)
• Blocks longer and shorter wavelengths for maximum contrast
• Optically polished flat substrate for sharp, clear images
• Advanced DWDM plasma-assisted coatings for durability and clarity

Optical Quality and Durability

The Baader OIII Nebula Filter is crafted with true optical quality glass substrates, ensuring that the filter maintains the full wavefront quality of the telescope.
