Baader Planetarium Contrast Booster Filter 1.25

5.0 out of 5 stars
1 customer reviews


The ultimate contrast filter for all refractive optical systems. Eliminates color error of inexpensive achromatic doublet objectives to provide the highest level of definition while correcting color balance. Surface details on the Moon and planets stand out boldly. You haven't really seen Jupiter's Great Red Spot though your achromatic refractor until you've used this filter.

Great for terrestrial viewing

By Philip Canard on October, 17th 2009

I have the Celestron branded version in 1.25 size. There was a coating problem with mine and Celestron replaced it. The replacement works fine for getting rid of atmospheric haze in daytime use. Sharpens up distant views significantly. For night use, it improves the view of Saturn significantly in my Nighthawk II scope. The Cassini division is easy with the filter.
