Product Info
Manufacturer Description
Much more than a simple minus-violet filter. Based on the popular Baader Moon&Skyglow filter, the Baader Contrast-Booster takes contrast enhancement and skyglow reduction to the maximum level possible from a filter. Not only does this filter deliver a significant enhancement of planetary and lunar contrasts, but it is designed to also totally eliminate the damaging blue defocused haze present in achromatic refractors. Gone are the annoying blue halo and obscuring haze that surround and smear resolution and contrast. Subtle contrasts and colors are boosted, while displaying the full resolution your scope is capable of.
The Contrast-Booster combines a special proprietary melt of Neodymium glass with a carefully designed 23 layer dielectric long-pass blocker on one face, and a 7-layer ultra-low antireflection coating on the other face. By aggressively filtering out the defocused blue wavelengths, a light yellow tint is imparted to objects (noticeably less than a typical yellow filter). The special coatings enable over 95% transmission across key portions of the visible spectrum (including H-Alpha). This results in a filter that retains the colors and color contrasts in tough subjects like Jupiter, without excessive image dimming. Cloud bands retain their ruddy red hues, but now become more striking in contrast. The Great Red Spot finally becomes easier. Planets and Lunarscapes are set against a jet black sky. The Contrast-Booster is a must for Solar observing (with Baader Astro Solar).
As many users have found, this is a great filter for Mars! The views of Mars with all telescopes (including reflectors and apochromats) benefit from the RGB filtration plus blue blocking.
Combined with the Baader UV-IR-Cut Filter, the Contrast-Booster makes the ideal filter set for digital imaging. Rather than add the cost of additional IR filtration (only needed for digital imaging), the Baader Contrast Booster has been optimized for visual use. Digital imagers can simply add our Baader UV-IR-Cut Filter when needed. The true 1/4 wave fineoptically polished surfaces guarantee the sharpness and contrast of the image. Filters are available in both 1.25" and 2" sizes.
The base substrate is a special custom melt of Neodymium doped glass, designed for specific transmission characteristics, and made only for Baader Planetarium. In addition to it's unique spectral characteristics, the Contrast-Booster offers Baader's hallmark optical and mechanical features that set it apart and result in the best possible image sharpness, contrast, and real-world durability.

Jun 15, 2018Exceptional!
Pros: Cons: Comments:I bought this filter to use with my 5" f6.5 achromat but as it turns out, I now even use it with my 8" sct for planetary observations! More than just a strong minus violet filter, it’s also a light polution filters and it also greatly increases contrasts.

May 13, 2016This filter is fantastic!
Pros:Sirius No False Color,Increases Contrast,Strongest Violet Blocker,Tightens Up Stars,For Achromatic Refractors,Removes False Color
Cons:None
Comments:I bought this filter for a 4'' achromatic refractor to remove the false purple fringing inherent in a doublet. It does the job as advertised and I leave it in the diagonal all the time. It also darkens the background sky and increases the contrast making for a more detailed image. The stars are much sharper using the filter than without. This is an amazing filter and well worth the money to bring your doublet refractor to the semi-apo level. On a rating of 1-5, this filter gets a 5. It really works!

Jan 30, 2015Excellent contrast booster
Pros:Strong Construction,Easy to Use,Quality Lenses,Lightweight,Accurate
Cons: Comments:I am using this on an ED 127 APO refractor. It boosts the contrast and brings out the detail in nebulas in suburban skies. I am very happy with the performance of this product and will continue to buy Baader products from Agena.

May 30, 2014My favorite filter
Pros:Easy to Use,Lightweight,Strong Construction,Quality Lenses
Cons: Comments:The Baader Contrast Booster filter is now my favorite all around filter. I have an SCT telescope and observe from my backyard in a semi-rual location. When this filter is in place it boosts contrast not only on planets, but on anything in the sky in general. It reduces the skyglow, giving the back ground sky a slightly darker appearance, and allowing the objects I'm viewing to stand out more.
Bottom Line: Would you recommend this item? Yes
One of the things that separates this filter from all the others, is that it doesn't mess with the stars natural colors. So this is one filter that will find a home in my diagonal, it adds a level of comfort to my viewing that I've come to prefer.This review was provided courtesy of AgenaAstro.com
May 30, 2013Good violet reduction - nothing else
Pros:No
Cons:No
Comments:I used this on my 4" doublet and its violet "shadowing" is mostly mitigated. Though I had hoped to gain some contrast in Jupiter's banding, I was dissapointed to see that the filter just colored it yellow.

Sep 21, 2012Baader Contrast Booster Filter
Pros:Compact,Quality Lenses,Strong Construction,Accurate,Easy to Use,Lightweight
Cons: Comments:I use this to improve the contrast and sharpness in my Vixen achromatic refractor. Big improvement in Sun observation with this filter and the Baader white light solar film filter.
Bottom Line: Would you recommend this item? YesThis review was provided courtesy of AgenaAstro.com
Jul 1, 2012Seeks to provide to you is satisfaction
Pros:Correction capability
Cons:Color balance
Comments:Currently Achromatic 8inch refractor is being used.
Bottom Line: Would you recommend this item? Yes
Moon, the planets, the light spread and chromatic aberration is caused to excel this product eliminates these parts.
It is a good product.
Archromatic Lens makes the Semi-Apochromatic level.
Collapse phenomenon is a little color balance.
Seeks to provide to you is satisfaction enough.This review was provided courtesy of AgenaAstro.com
