#1	Nebula filter for increasing contrast also suitable for use with smaller telescopes
#2	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
#3	Can be used at both lightpolluted and dark sky sites blocks the light from mercury and sodiumvapour lamps
#4	2 inch filter thread each Astromania Ultra High Contrast Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the OIII and Hbeta emission lines
#5	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
