(Note: for solar observation use only in combination with Astro-Solar Safety Film!)

• Eliminates the colour inherent in popular economy Refractor.
• Clearly puts the real quality of the lens on display.
• Removes the bluish "hue" (lack of contrast) during lunar, planetary, solar and terrestrial observation.
• Strongly emphasizes surface detail on Jupiter and Mars! If you have never seen the GRS (Great Red-Spot) on Jupiter - with this filter you will.
• Over 95% transmission - provides a bright brilliant image compared to the usual dark green color filters, used to bring out detail on Jupiter. Colour recognition will be retained.
• The ultimate in lunar filters! - Moon (and Sun!) appears much more natural in colour (with a slight yellowish tint), compared to the usual low priced dark green Moon-filters, usually offered for beginners telescopes.
• Completely removes distracting false colour and the resulting smeared and washed out image details. *You have never ever seen the Moon (or the Sun with Astro Solar Film) so tack sharp in an economy priced telescope.
• Blocks atmospheric "stray Light" (sky glow). Sky-background turns in to pitch black.
• Fits each and every standard filter thread of 1.25" eyepiece.
• Used with the (Optically polished) Baader Infrared Cut-Filter. In this combination all the blue scatter as well as unfocused near infrared light is completely removed - an absolute MUST for digital imaging.
• No deterioration of resolution with magnifications of 200x and more.
