Baader Telescope Filter

Like new H-Alpha 7nm 2" filter.

The number of sunspots changes permanently, as well as their shape and size. Depending on magnification, you may even be able todiscern the core and boundary areas of a sunspot (umbra and penumbra).

The L filter is a standard Baader UV/IR blocking filter and can be used for focusing, as well as for taking a luminance image. The C filter is clear glass, and is used for focusing images with RGB and line filters.

2 "Baader H-alpha CCD Filter, HWB 7 nm, Plane-optically polished, with 2" mounting thread. Box contents: H-alpha narrowband Filter 07nm 2 ". We are here to help! General Interest.

'Adaptor with a fully T-2External Thread and internal with 1 filter thread. Filter holder with T2_ External Thread and m28,5mm inner thread. Adapter with continuous T-2 outer thread and 1.25" interior filter thread.

As with all Baader Planetarium Filters, the Solar Continuum possesses all the trademark Baader filter qualities. The new Baader Solar Continuum filter is designed to enhance the visibility of solar granulation and sunspot details.

Filter is 105mm with step down ring to 95mm. No other step down rings included. Included are 2 filters protect the filter film. Series 1 Vivitar 105mm multi coated UV and XIT pro series HD multi coated UV 95mm.

This bandpass provides significant contrast for high-resolution imaging of granulation, flares, sunspots, and other features that are prominent in CaK light. The CaK filter must be placed. The Baader Herschel Safety Wedge Solar Prism may also be used as the energy rejection filter in place of the AstroSolar Photo Film.

Manufacturer part numbers: FSOL-1D or 2458392. The double stacked version of the Baader Planetarium Solar Continuum filter is designed to enhance the visibility of solar granulation and sunspot details.

Combined with the Baader UV-IR-Cut Filter, the Contrast-Booster makes the ideal filter set for digital imaging. Digital imagers can simply add our Baader UV-IR-Cut Filter when needed. Filters are available in both 1.25" and 2" sizes.

The Baader IR-Pass filter blocks wavelengths below 670 nm. At these longer wavelengths, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing). High optical quality, Striae-free substrate, and high efficiency multicoatings result in the sharpest and highest contrast image possible.

These filters are planoptically polished with Baader's famous Phantom Coating Group Multicoatings. This 2" filter has a neutral density of 1.8, so its transmission factor is 1.5%. It has a standard 2" male filter thread (M28.5x0.6) so it can be screwed on to virtually any astronomy eyepiece or accessory that has 2" filter threads.

The NEW Baader 2" Cool-Caramic Safety Herschel Prism is the finest solar wedge ever produced for amateur use. It is the culmination of Baader's many years of experience in the design and production of Herschel Wedges.

Manufacturer part # FSIIHS-1 or 2459395. Conventional narrowband filters cause a heavy loss in transmission due to the strong CWL-shift. Baader f/2 Highspeed Narrowband CCD Filter with preshift and LPFC (low profile filter cell): S-II - 1.25".

Manufacturer part # FOIIIHS-1 or 2459394. Conventional narrowband filters cause a heavy loss in transmission due to the strong CWL-shift. Baader f/2 Highspeed Narrowband CCD Filter with preshift and LPFC (low profile filter cell): O-III - 1.25".

Manufacturer part # FHALHS-1 or 2459393. Conventional narrowband filters cause a heavy loss in transmission due to the strong CWL-shift. Baader f/2 Highspeed Narrowband CCD Filter with preshift and LPFC (low profile filter cell): H-Alpha - 1.25".

The high transmission and fringe reduction work great for both planetary and deep sky imaging. Baader's newest addition for Achromat owners. The Semi-APO filter combines a stronger Fringe Killer coating formula with the Moon & Skyglow Neodymium substrate.

Baader Planetarium has introduced the world's finest UV/IR cut filter. - Sharp cutoff below 400nm. Why spend all your money on quality primary optics - only to place a lower grade filter optic in the path?.

The Baader IR-Pass filter blocks wavelengths below 670 nm. At these longer wavelengths, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing). High optical quality, Striae-free substrate, and high efficiency multicoatings result in the sharpest and highest contrast image possible.

This family of solar filters is made in the most elaborate way, and its construction and design is superior to that of the ASBF and ASSF line of Baader filters. Ideally, AstroSolar film must not be put under stress, either during mounting of the film or during any temperature change.

The O-III benefits from the precision fine optically 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.

Achromat owners rejoice! Baader Planetarium has taken minus violet filtration to a new level. The Fringe Killer brings a type of filtration, never before seen, to the amateur. Rather than simply trimming the shorter wavelengths at a chosen wavelength and slope like all other minus violet filters, the Fringe Killer carefully attenuates a specific region of the spectrum.

These are intended for applications for apertures up to 6" where the highest magnification will not exceed about 120x. The world's finest objective solar filter material - Baader Planetarium's AstroSolar Safety Film - is now available in a complete range of high-quality mounted Baader Solar Filters.

The lower sensitivity of interline transfer CCDs benefits from the more efficient 35nm FWHM. The sharp bandpass and > 90% high efficiency coatings make the Baader H-Alpha filter superior to the common colored-glass based filters; all at a reasonable price.

In addition to their transmission properties, the Baader coatings were developed with another key goal in mind - eliminate the annoying reflections present in other narrowband astro-filters. To achieve this freedom from reflections, along with excellent out of band blocking, required careful design and testing of the coating stacks.

Another unique new filter from Baader Planetarium. The Baader Venus Filter enables amateurs to successfully image in the deep UV, a spectral region normally inaccessible. The latest coating technologies permit the Baader Venus Filter to transmit from 300nm to 400nm, with a peak transmission of 80%!

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.

Manufacturer part #: FCFY-2 or 2458311. Efficiencies of the three longpass filters (Red, Orange, and Yellow) peaks at 98%, and efficiencies of the three bandpass filters (Green, Blue, Dark Blue) achieve 70%.

The result is a filter that leaves natural colors mostly intact, but significantly enhanced. The image on the left was taken without filtration, while the image on the right was taken through a Moon & Skyglow.

When imaging Jupiter in visible light, for example, the equatorial belts may appear white due to ammonia at the higher levels. Very narrow bandpass of just 8nm. Coatings dielectrically applied in a complex and precise process developed by Baader.
