OK.... make it $70 + postage:D

Really? No-one looking for all these mint condition filters at this price?

more details on the contrast booster:


Properties:

Eliminates the color error of economy refractors

Clearly puts the real quality of the lens on display

Removes the bluish "hue" (which equals lack of contrast) during lunar, planetary, solar (with appropriate solar filter) 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. Color recognition will be retained!

The ultimate in lunar filters! - Moon (and Sun!) appear much more natural in color (with a slight yellowish tint) compared to the usual low-priced dark green moon filters usually offered with beginner's telescopes.

Completely removes distracting false color and the resulting smeared and washed out image details. You have never ever seen the Moon so tack sharp in an economy-priced telescope!

Blocks atmospheric "stray light" (skyglow). Sky-background turns into pitch black!

Fits each and every standard filter thread

Combines with the (planoptically polished) Baader Infrared Cut-Filter. In this combination all blue scatter as well as unfocused near infrared light is completely removed - an absolute Must for digital imaging!

Planoptically polished, suitable for being used in front of a binocular viewer, or for afocal image projection during digital imaging (way in front of the focal plane!)

No deterioration of resolution with magnifications of 150x and more as with "raw polished" (flame polished) glass!

Substrate (glass melt): Neodymium doped glass

Coating / rear face: 7-layer hard-multicoating, featuring 0,2% reflection

Coating / front face: 23-layer dielectric long pass blocker Ionbeam hardened coatings on both faces.

Absolutely scratch resistant - may be cleaned any time without fear.

Thanks, and enjoy:thumbsup:
