  1. The L-Pro Astrophotography CCD filter is a filter for improving the contrast of deep-sky objects and dampening the sky background.

    • blocks UV and IR (700 - 1100 nm)
    • high transmission at passband
    • improved color balance for DSLRs and One-Shot Color Astro Cameras, e.g. ASI Color Cameras cooled or uncooled by ZWO.
    • high optical quality
    • in 1.25" filter cell
    • The L-Pro Nebula filter permits roughly 3x longer exposure times than without a filter and therefore improves contrast significantly.

  2. Smart solar filter for Equinox and Evscope which works with all Unistellar telescopes

    • Unlock the secrets of Solar Activity
    • Observe the Sun in less than 2 Minutes
    • Safely Experience With Your Family
    • A new solar experience available on UNISTELLAR App (iOS & Android)
    • Witness once-in-a-lifetime solar events

  3. Anti-pollution filter effectively isolates the emission lines not only of emission nebulae but also of galaxies, clusters or globular clusters and reaches a maximum transmission of up to 97%.

  4. Reduce glare and increase contrast of the Moon with the Celestron 1.25” Moon Filter. Also useful for extra bright planets as well as terrestrial viewing over sand or snow. Threads onto most 1.25” eyepieces in seconds

  5. 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.

  7. The L-Pro CCD filter improves the contrast of deep-sky objects and reduces the sky background.

  8. The advantage of the L-eXtreme filter is that there is no transmission between the H-beta and OIII lines, as there is no nebula emission lines there. In this case, it isn't letting light pollution come through so that maximize nebulas signal and make the sky background darker while imaging. The L-eXtreme filter should better isolate the emission lines only and better protect from light pollution.

  10. 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.

  11. 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
