Nebula filter for increasing contrast; also suitable for use with smaller telescope; 1.25 inch filter thread; Astromania uhc filter is individually inspected and proudly inscribed with percentage of light transmittance of O-III and H-beta emission lines
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
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
