A unique filter for many different astronomical tasks - incomparable in image sharpness compared to combinations of basic colour filters, made of raw polished glass. The Baader Contrast-Booster is specially designed to improve the ubiquitous beginner telescope - to provide a professional replacement for the simple "dark green" Moon and Solar-Filters made of ‘raw polished" glass.

(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.
