Price History
- Nebula filter for increasing contrast, also suitable for use with smaller telescopes.
- Many objects only first become visible at all when using an UHC filter. But also, highlights such as the Orion, Lagoon or Swan nebulae, show a whole new side to them.
- Can be used at both light-polluted and dark sky sites. Blocks the light from mercury and sodium-vapour lamps.
- 1.25" filter thread, each Astromania Ultra High Contrast Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the O-III and H-beta emission lines.
- As many celestial objects, such as nebulae, radiate at other wavelengths, a considerable increase in contrast can be achieved by this. The background sky appears darker and all at once, faint details become visible.
