WebOct 2, 2024 · The best approach when the Moon is in the night sky is to use a monochrome camera and a hydrogen-alpha filter. The narrower the bandwidth (3nm compared to 7.5nm, for example), the better it will combat moonlight. Bright nebulae tend to have lots of hydrogen-alpha signal in them, whereas galaxies and reflection nebulae contain almost … WebSep 25, 2024 · The most common narrowband filter for visual observation of nebulae is the OIII filter, so called because it only passes the two blue-green wavelengths emitted by doubly-ionized oxygen at 496nm and 501nm (Figure 8). These filters have a passband just 10-15nm wide, and they do not pass the 486nm spectral line from H-beta.
