Vai al moduloBaader O-III 10nm 1.25" Filter for Visual Observation
The Baader O-III 10nm filter is designed to enhance contrast and visibility when observing diffuse and planetary nebulae, delivering cleaner and more detailed views through your telescope. It performs exceptionally well on objects such as the Veil Nebula, Lagoon Nebula (M8), Omega Nebula (M17), Ring Nebula (M57), Dumbbell Nebula (M27), and Eagle Nebula (M16).
Enhanced Contrast with Selective Bandpass
This filter accurately isolates the two ionized oxygen emission lines O-III at 496 nm and 501 nm, offering a narrow 10 nm bandpass. By effectively blocking unwanted wavelengths, it improves contrast and reveals finer nebular structures even under moderately light-polluted skies.
High Optical Performance
Unlike many generic O-III filters, the Baader O-III 10nm fully blocks wavelengths outside the useful spectral range, maximizing the signal-to-noise ratio and improving visual clarity. It is an essential accessory for observers seeking optimal deep-sky performance.
