• Improve your view of nebulae with your Celestron Origin, especially from urban and suburban skies. This filter blocks light pollution, increases image contrast and darkens the sky background for sharper, more contrasted images.
• This filter transmits only the key Hα-Hβ-OIII wavelengths from emission nebulae, making their colors stand out from the dark background. It also blocks light pollution, allowing it to be used even from urban and suburban skies.
• Made for the Origin 6" RASA lens. Unlike similar filters with narrower bandwidths, this filter was specifically designed to work with the Origin's fast f/2.2 lens.
• Made of Schott glass with anti-reflective coatings, the surfaces of this filter are completely flat and free of defects.

This new, All-In-One design marries high quality components of a telecentric barlow, adapters, snouts and Daystar hydrogen alpha filter into one simple assembly.

Extra narrowband SII-CCD 6.5nm filter (Sulful II for CCD) is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 672nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).

Extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).

The LRGB filter kit is designed for maximum contrast and with extremely high gradients for a clear differentiation of light colors

EOS Clip version of the famous L-eNhance filter by Optolong

Optolong L-eNhance is a dual-band pass filter which has been designed for DSLR (digital SLR), color CMOS and monochrome CCD cameras. The convenience and cost effectiveness of this filter allows amateurs to image a rich selection of astronomical images, even in bright, heavily light-polluted areas. It effectively isolates the H-Alpha, H-Beta, and Oxygen III nebula emission lines and achieves a maximum transmission of up to 90%. The performance of this filter delivers superb images.

Bester H-alpha-Linienfilter für die Astrofotografie von Emissionsnebeln mit höchstem Kontrast und der Wiedergabe zartester Nebeldetails.

♦ schmalbandiger (<=7 nm) Linienfilter für wichtige Nebellinie
♦ bevorzugt für CDD-Kameras mit Full-Frame-Transfer-Technik
♦ 2 mm dick und somit homofokal mit vielen anderen Filtern von Optolong
♦ Interferenzfilter
♦ feinoptisch poliert
♦ mehrschichtig hartvergütet - reflexfrei und weitgehend kratzfest

• AstroSolar® ECO-size Safety Film 5.0 for solar observation and photography at high magnification
• Size: ca. 140 x 155 mm, incl. DIY-instructions and DIY cutting-template – telescope quality – Optical Density (OD) = 5.0
• Safe for visual solar observation (with additional optics) and imaging
• This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics
• For more than 25 years on the market, the only film-material made to not deteriorate the optical wavefront, it does allow to attain high magnification with any long-range optics without reducing sharpness or contrast of the solar surface.
• The film is from the same material as our proven AstroSolar® Safety Filme 5.0 in A4-size, due to high demand now availble in a smaller size at an economical price, suitable as solar filter for small telescopes, finders, binoculars, spotting scopes and camera lenses
