Baader Planetarium Semi-APO Telescope Filter Size - 2 Inch Semi-APO Filter

Available in 1.25'' or 2'' format
Delivers amazingly neutral views
Cuts annoying violet fringe
Amazing on Jupiter or Mars
High-end Baader quality

Baader's newest addition for Achromat owners. The Semi-APO works like its name implies - delivering an amazingly neutral view, while cutting most of the annoying and contrast-robbing violet fringe that plagues all achromats. The Semi-APO filter combines a stronger Fringe Killer coating formula with the Moon&Skyglow Neodymium substrate. The result is similar performance to the Fringe Killer + Moon&Skyglow combination, but with a slightly stronger violet cut - and at an even greater $ $ value. The Semi-APO filter benefits from all the host of world-class Baader filter attributes. The Semi-APO filter is truly the world's most advanced 'minus-violet' type filter in every regard. Its high efficiency and neutral coloration make it practically disappear in use - while making most of the violet fringe disappear! The effects on sharpness, contrast, and aesthetics are remarkable, even with small refractors. The RGB enhancement of the Neodymium substrate actually boosts color contrasts, particularly for Jupiter and Mars.

As a side benefit, the Semi-APO filter has also proven to be the best Mars filter we've used - with ALL Telescopes, including large Dobsonians, SCTs, and Apochromats. The unique properties that result from the combination of the Fringe Killer's blue wavelength attenuation (attenuation - not total elimination), plus the selective Neodymium RGB passbands, result in a significant contrast enhancement of Martian features. The image retains its natural coloration and brightness, and the optically polished surfaces maintain every bit of the image sharpness, unlike other manufacturers' filters.

The high quality of Baader Planetarium filters permits their use well ahead of the focal plane with no image degradation (ie, for cameras or binoviewers). The inclusion of Baader's renowned UV/IR Cut coatings on the

Baader Planetarium 2" Oxygen III Nebula Filter FOIII-2 Reviews

Baader Planetarium 2" Oxygen III Nebula Filter FOIII-2

The Baader Planetarium Oxygen III Filter delivers the absolute highest contrast views of many diffuse and planetary nebula. For many objects, the Baader Planetarium O-III reveals a level of intricate detail that rivals the best deep sky photographs. Our favorite filter for the majority of nebula, especially The Veil, Lagoon (M8), Swan (M17), Ring (M57) and Dumbell (M29). With a large scope, you can even view the famous 'Pillars of Creation' in M16 (Eagle).

The Baader Planetarium Oxygen III Filter perfectly isolates the two doubly ionized oxygen lines (496 and 501nm), through a very sharp and narrow bandpass (8.2 nm wide!, the narrowest of any O-III filter). Unlike other O-III filters, the Baader Planetarium O-III completely blocks longer and shorter wavelengths (ever wonder why some O-III filters appear RED?, instead of the correct 500 nm Teal color). The result is the highest contrast achievable in an O-III filter.

The Baader Planetarium Oxygen III benefits from the precision fineoptically polished flat substrate, and advanced DWDM plasma assisted coatings. As a result, the Baader O-III will not degrade image sharpness or impart double images. To prevent deterioration from cleaning or exposure to moisture, some other filters even resort to sandwiching their delicate coatings between two layers of filter glass, resulting in potential blurred or double images. Contrary to myth, nebula filters are often useful at high magnifications, where image quality counts. Baader O-III filters can take high magnifications, and stars retain their pinpoint sharpness, even if the filter is used far ahead of the image plane (ie, for imaging use, or ahead of a star diagonal or binoviewer). Combine with our UV/IR filter for the ultimate in O-III deep sky imaging.

Baader Planetarium Solar Continuum Filter, 2" FSOL-2

The Baader Solar Continuum Filter enhances the visibility of solar granulation and sunspot details.
Boosts Contrast and reduces effects of atmospheric turbulence
Works with all telescopes
The Baader Solar Continuum Filter Works for both visual observation and imaging
Can be used a star test filter

Baader Solar Continuum Filter 2"

Superb Baader Planetarium Quality

The Baader Solar Continuum Filter is truly a unique product from Baader Planetarium. A great accessory for solar observation the Baader Solar Continuum Filter is a great compliment to any expensive solar telescope.

The new Baader Solar Continuum filter is designed to enhance the visibility of solar granulation and sunspot details. By transmitting a specific spectral region around 540nm, free of emission and absorption lines, the Solar Continuum filter is able to boost contrast and reduce the effects of atmospheric turbulence. With the Solar Continuum filter in place, images snap to focus, and granulation becomes regularly visible. Details at the limit of visibility become easier to hold, and image motion reduced.

The Solar Continuum filter works well in all types of telescopes, for both visual and imaging. Users of SCTs and achromatic refractors will find it particularly beneficial, as it completely excludes the red and blue wavelengths, and centers on the peak visual wavelengths where the telescope optics are sharpest and free from chromatic aberrations. For digital imaging, we also recommend the Continuum filter be combined with our UV/IR Cut Filter (to completely cut the defocused far infrared wavelengths).

The Solar Continuum filter also makes the perfect star test filter. It's narrow bandpass and complete blockage of longer and shorter wavelengths make it superior to standard green colored filters for testing refractors at their center design wavelength (and peak visual wavelength). With this filter, more accurate appraisals of optical quality can be made, without the effects of spherochromatism or secondary color error. Due to the narrow 10nm bandpass, star testing through the Solar Continuum filter will require a bright test star.

As with all Baader Planetarium Filters, the Solar Continuum possesses all the trademark Baad

Meade Series 4000 #11 Yellow-Green Filter Color 1.25" 07513

Color filters are an essential tool of the lunar and planetary observer, for filters permit the observation and photography of surface detail that is often virtually invisible without filtration.xFilters solve, or greatly reduce, the effects of two basic observing problems: (a) Irradiation is the fuzzying of a boundary between lighter and darker areas of the Moon or a planetary surface and can be caused either by the effects of highly contrasting light impacting the human eye or by the motion of the Earth's atmosphere, through which the observation is being made. (b) Contrast is the separation of adjacent surface regions according to their color; for example, a light green area on Mars can become mixed in the eye with an adjacent light yellow area, to the effect that the combined area appears yellow-green, unseparated into its component regions.The use of a Meade Series 4000 color filter can mean the difference between seeing small craterlets in the floor of Clavius on the Moon and not; it can mean the difference between seeing five or six whirls, festoons, and loops in Jupiter's north equatorial belt and seeing one or two; it can mean the difference between seeing the inner crepe ring of Saturn and not.

Baader Planetarium UHC-S Nebula Filter - 2" FUHC-2 Reviews

Baader Planetarium UHC-S Nebula Filter - 2" FUHC-2

The Baader Planetarium UHC-S Nebula filter excels at delivering a high-contrast and natural view of emission nebula without excessive dimming and loss of background star fields. It's the perfect filter for viewing emission nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire passband, with total blockage of prominent light pollution lines. This translates to maximum image brightness and contrast. Owners of smaller, 4"-10" telescopes will especially appreciate the high efficiency, and larger scope users will love the rich star fields and detailed subtle nebular shadings that are left intact.

The Baader UHC-S manages to improve on the contrast of the typical broadband or so-called "Deep Sky" filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. Most other "UHC" filters tend to excessively darken the sky and star fields, leaving the nebulae looking artificial and flat, set against an empty background. The high transmission, sharp cutoffs, and more moderate 60nm passband of the Baader UHC-S filter retains a more natural view, yet significantly boosts overall contrast. Imagers will appreciate the broader passband and inclusion of an extremely efficient H-Alpha passband (>99% @656nm), as well as the extreme optical quality.

At the heart of the Baader UHC-S filters are their special fineoptical substrate polishing process and advanced coating design. The result is a filter that imparts no image degradation, unlike other filters. To prevent deterioration from cleaning or exposure to moisture, some other filters even resort to sandwiching their delicate coatings between two layers of filter glass, resulting in potential blurred or double images. The combination of hardened coatings and fineoptical substrate of the Baader UHC-S avoids this image degradat

AstroZap Baader Solar Telescope Filters Size - Meade ETX125 Reviews

AstroZap Baader Solar Telescope Filters Size - Meade ETX125

Made with Baader AstroSolar™ 18Ga. film Filter cell
Aluminum, powder-coated frame with double coated film
Neutral color balance enables use of color filters
Secures onto objective lens with 3 thumbscrews

Baader AstroSolar™ film Filter cell constructed from lightweight 18Ga. aluminum and powder coated white. Heavy duty threaded inserts and nylon thumbscrews insure a secure fit.

With AstroSolar™ the Sun appears in neutral white. Other films and some glass filters produce a blurry bluish or reddish Solar image, thereby cutting part of the spectrum. Especially with an orange sun, it is very hard to see faculae regions which are visible predominantly in the blue wing of the spectrum.

Due to it's neutral color balance, AstroSolar enables the use of various color (or interference) filters which allows the observer to concentrate on certain spectral passbands for investigations of different layers within the solar "atmosphere".

Eye safety

AstroSolar™ is essentially free from pinholes, since - other than with even the most expensive glass filters - it is coated on both sides, so that the chance of two pinholes overlapping each other is extremely faint. Pinholes do appear, but to 1 out of 10000 only in optical density 2.5! Baader AstroSolar™ safety film has been approved for eye safety by the National Bureau of Standards in Germany, the PTB. Unlike any other Solar Filter on the market, AstroSolar™ is CE-tested according to EG-Norm 89/686 and EN 169/92 ( notified body 0196). All processes connected to this product have been thoroughly tested. Coatings are inspected constantly for consistency to ensure your eye safety!

1.25" Orion Hydrogen-Beta Eyepiece Filter

Orion's Hydrogen-Beat eyepiece filter makes it possible to view the elusive Horsehead, California, and Cocoon Nebulas in dark skies
Selective band-pass filter transmits only the hydrogen-beta light these faint nebulas emit
Filter allows you to observe targets that are considered trophies of visual astronomy
Best used with a moderate to large aperture telescope and clear, dark skies
Threaded to fit 1.25" eyepieces and threaded diagonal barrels

Our Hydrogen-Beta Filter may be the only way to see the faint and elusive Horsehead, California, and Cocoon Nebulas. It blocks everything but the hydrogen-beta light these faint nebulas emit, providing the contrast needed for viewing. By isolating the hydrogen-beta spectral line centered at 486.1 nm in a 12nm band-pass and blocking other wavelengths, it effectively blackens the background sky, allowing the faint nebula to become clearly defined. It increases contrast even under dark skies so you can visually capture these prized targets. Use with a moderate to large aperture telescope under clear, dark viewing conditions. Threaded to fit 1.25" and 2" eyepieces and diagonals.
