  • Antlia H-beta and OIII Filter for visual and photography - 1.25" Mounted

    Antlia H-beta and OIII Filter for visual and photography - 1.25" Mounted

    Antlia H-beta and OIII Filter for visual and photography - 1.25" Mounted

    Antlia HB-OIII filter is engineered specifically for night visual nebulae observation at a high contrast and Deep-sky astrophotography. Its transmission is 90% or greater at critical wavelengths (OIII 500.7nm, OIII 495.9nm, and H-Beta 486.1nm). You’ll notice much higher contrast boost to observe Planetary Nebula, Supernova Remnant, Emission Nebula, Diffuse Nebula, and extremely faint nebulae by Antlia HB-OIII filter.

    When it is used for Astro Deep-sky imaging, it enhances the details of the OIII and H-Beta emission lines with astronomical cameras and DSLRs.

  • Antlia Tri-band RGB Ultra Filter - 2" Mounted

    Antlia Tri-band RGB Ultra Filter - 2" Mounted

    Antlia Tri-band RGB Ultra Filter - 2" Mounted

    It is designed for light pollution suppression for OSC and Mono cameras. The spectral design selected the most substantial information in the RGB bands, which makes Antlia Triband RGB Ultra Filter possible to shoot over 90% of deep sky objects, in addition to its excellent performance on emission nebula, different from other ultra-narrowband filters, it is able to capture galaxies, reflection nebulae, and star clusters from a Bortle 8 location to Bortle 1 while presenting more balanced RGB colors in your images. Also, it has a broad bandpass designed to cope with faster optics up to the f/2 focal ratio.

  • Optolong L-Quad Enhance Filter (L-QEF) Light Pollution Suppression filter - 2"

    Optolong L-Quad Enhance Filter (L-QEF) Light Pollution Suppression filter - 2"

    L-Quad Enhance Filter (L-QEF) 

    L-Quad Enhance Filter (L-QEF) is a quad bandpass light pollution suppression filter for colour cameras. It effectively suppresses the transmission of light pollution wavelengths, especially light pollution generated by artificial lighting (including mercury and sodium lamps), as well as the effects of natural skylight-induced effects on the shot, thus effectively enhancing the contrast and details of the celestial bodies, and making the objects more distinct and stereoscopic. This filter provides better color balance while improving resistance of light pollution. L-QEF can be used for both wide field astrophotography, such as the Milky Way in Summer and Winter, and deep sky objects such as nebulae, galaxies, star clusters, and so forth; It allows you to save a lot of time during the shooting process and get better results at the same time. The design of quad bandpass maximises the colour balance of nebulae, galaxies and other broadband spectral targets.

  • Antlia ALP-T Dual Narrowband Ha & OIII 5nm Filter - 36mm Unmounted

    Antlia ALP-T Dual Narrowband Ha & OIII 5nm Filter - 36mm Unmounted

    Antlia ALP-T Dual Narrowband Ha & OIII 5nm Filter - 36mm Unmounted

    The Antlia ALP-T dual band 5nm filter is a dual line-pass filter which was designed to be used primarily with one-shot color (OSC) cameras such as DSLR's or astronomical OSC cameras. It can also be used as a narrowband filter for monochrome cameras to save imaging time. The advanced multi-coatings on our ALP-T ultra dual band filter effectively isolates the red Ha and the blue-green OIII lines light from emission nebulae, with almost total suppression of optical density (OD)4.5 on unwanted wavelengths from light pollution, moonlight, and airglow. The result is that our ALP-T dual band 5nm filter creates a superior signal-to-noise ratio and better contrast in your images.

  • Antlia ALP-T Dual Narrowband Ha & OIII 5nm High Speed Filter - 36mm Unmounted

    Antlia ALP-T Dual Narrowband Ha & OIII 5nm High Speed Filter - 36mm Unmounted

    Antlia ALP-T Dual Narrowband Ha & OIII 5nm High Speed Filter - 36mm Unmounted

    ALP-T Dual Band 5nm Highspeed Filters are further optimized to work with high-speed imaging systems by shifting slightly the passband and center wavelength. Using these highspeed filters between optics f/2.2 and f/3.6 shows much stronger and more contrasted in nebulae imaging compared to the standard version.

  • Antlia ALP-T Dual Narrowband SII & Hb 5nm Filter - 2" Mounted

    Antlia ALP-T Dual Narrowband SII & Hb 5nm Filter - 2" Mounted

    Antlia ALP-T Dual Narrowband SII & Hb 5nm Filter - 2" Mounted

    The ALP-T dual band 5nm SII&Hb filter is a dual line-pass filter, which lets the deep red Sulfur-II line and the blue Hydrogen-Beta line through and is used with one-shot color (OSC) cameras such as DSLR's or astronomical OSC cameras. It is a significant addition to the popular Antlia ALP-T dual band 5nm Ha&OIII filter and enables false-color images and narrow-band nebula images using OSC. When capturing data with this filter, the nebulae are recorded with greater contrast against the background than without it.

  • Optolong L-Ultimate 3nm Dual-Band Filter - 2"

    Optolong L-Ultimate 3nm Dual-Band Filter - 2"

    Optolong L-Ultimate 3nm Dual-Band Filter - 2" 

    The L-Ultimate is a 3nm dual band filter designed to drastically reduce the effect of light pollution. The 3nm isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue). It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background. It also blocks artificial light from mercury vapor lamps, high and low pressure sodium vapor lights, and unwanted natural light caused by the emission of neutral oxygen in our atmosphere, maximizing the transmission of the main emission lines of the nebula in OIII (496nm and 500nm) and H-alpha (656nm). Used with DSLR, color/MONO CMOS and CCD, this filter is suitable for telescopes with an f-ratio of f/4 or higher (slower).
