- 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
- 2 inch filter thread; each Alstar 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
- Can be used at both light polluted and dark sky sites; Blocks the light from mercury and sodium vapour lamps
- 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
- Nebula filter for increasing contrast; also suitable for use with smaller telescopes
