27001 H-Alpha 3nm

The 27001 H-alpha 3nm Bandpass bandpass filter transmits a single spectral band while blocking light on either side.

H-alpha filters are essential for imaging nebulae and other objects which are rich in ionized hydrogen. At 656.3nm, a narrow-band emission filter is required to separate H-alpha from the SII doublet (671.6nm and 673.1nm).

27002 H-Alpha 5nm

The 27002 H-alpha 5nm Bandpass bandpass filter transmits a single spectral band while blocking light on either side.

27002

H-alpha filters are essential for imaging nebulae and other objects which are rich in ionized hydrogen. At 656.3nm, a narrow-band emission filter is required to separate H-alpha from the SII doublet (671.6nm and 673.1nm).

27003 H-Alpha 8nm

The 27003 H-alpha 8nm Bandpass bandpass filter transmits a single spectral band while blocking light on either side.

27003

H-alpha filters are essential for imaging nebulae and other objects which are rich in ionized hydrogen. At 656.3nm, a narrow-band emission filter is required to separate H-alpha from the SII doublet (671.6nm and 673.1nm).

27065 H-Alpha 3nm (optomized for f2.8-f3.6)

27065 H-alpha 3nm Bandpass optimized for f/2.8-f/3.6 – Single Band Filter optimized for Astronomy

27065

H-alpha filters are essential for imaging nebulae and other objects which are rich in ionized hydrogen. At 656.3nm, a narrow-band emission filter is required to separate H-alpha from the SII doublet (671.6nm and 673.1nm). Chroma’s f/3.0 filters are designed to minimize spectral shift and hold their shape better in an f/3.0 beam.
