  • IDAS NBX Nebula Booster Filter, 52mm, mounted dual bandpass, H-α & OIII

    $299.00
      • 10nm bandpass for Ha and OIII respectively.
      • IDAS-proprietary “flat-top”, “steep cut-off” and “off-center” design eliminates the emissions’ signal loss due to the spectrum shift until F2 speed.
      • Available 48mm and 52mm mounted (2.5mm thickness)
      • No IR blocker required

    IDAS NBX Filters are designed to enhance the contrast of Hα and OIII emission nebula, yet accommodate the filter spectral shift when used with modern fast optical systems. This dual-band filter is ideal for one-shot color cameras as well as mono-color astronomical cameras

  • Astrodon LRGB Gen2 E-Series Tru-Balance Filter Sets

    $547.00$2,740.00

    Filters in stock ship usually ship within 1 week. Filters on back-order ship usually ship within 3-6 weeks.

    You may click the “Get an alert” button to be notified when an out of stock filter is back in stock. It is necessary to pay for back-ordered filters immediately to reserve your spot in our wait list. Often we have more orders for out of stock filters than we have incoming filters. Many Astrodon filters are perpetually out of stock for this reason.

    SIMPLIFY YOUR IMAGING!
    Astrodon LRGB Gen2 E-Series Tru-Balance Filter Sets were designed for cameras containing the full-frame KAF8300, KAF3200, KAF6303, KAF16200, KAF16803 sensors, as well as most Sony and back-thinned sensors and other cameras with Progressive Scan, Front Illuminated or Back Illuminated Sensors.

  • Astrodon 1.25″ One Shot Color Luminance Filter (UV / IR Cut)

    $75.00

    Astrodon 2″ One Shot Color Luminance Filter (UV / IR Cut) is used primarily to “bracket” the color-corrected band of refracting telescopes. This filter can also be used as a “visible” filter in RGBV (red-green-blue-visible) astrophotography with reflecting telescopes.

  • Astrodon L2P Light Pollution Luminance Filter

    $169.00

    Our L2P filters are designed to be used the same way that you would use a regular Astrodon Luminance filter, either by itself or as part of a LRGB filter set. The L2P filters are recommended for imaging in urban and/or light polluted areas.

  • Astrodon 3 nm Narrowband Filters – H-α 3nm

    $564.00$2,495.00

    You may click the “Get an alert” button to be notified when an out of stock filter is back in stock. It is necessary to pay for back-ordered filters immediately to reserve your spot in our wait list. Often we have more orders for out of stock filters than we have incoming filters. Many Astrodon filters are perpetually out of stock for this reason.

    H-α (hydrogen-alpha) at 656 nm (nanometers) is deep red in color and the most popular narrowband filter. Hydrogen is ubiquitous in the cosmos and is present in emission nebula (North American, Pelican), planetary nebula (Dumbbell, Ring), Wolf-Rayet objects (Crescent, Thor’s Helmet) and supernova remnants (Veil). Many imagers like to present just a black-and-white H-α image of an object. It is has a beauty all by itself, like an Ansel Adams photo. However, most imagers blend their H-α data into their red RGB data to enhance structural detail while maintaining a “natural” look. Therefore, the H-α filter should be your first narrowband addition to your LRGB filters. The basic imaging set of 5 filters becomes LRGBH-α.

    Astrodon H-α filters have a center bandwidth of 656.3 nm

  • Astrodon 3 nm Narrowband Filters – OIII 3nm

    $564.00$2,495.00

It is necessary to pay for back-ordered filters immediately to reserve your spot in our wait list. Often we have more orders for out of stock filters than we have incoming filters. Many Astrodon filters are perpetually out of stock for this reason.

    The next filter to complement your LRGBH-a set is an oxygen filter. OIII (“ohthree”) emits light near 500 nm and is a blue-green- or teal-colored filter. Many of my images of planetary nebula and supernova remnants are taken only with H-a and OIII filters. They show great structural detail, but have natural colors, looking like an RGB image.

    Astrodon OIII filters have a center bandwidth of 500.1 nm.

  • Astrodon 3 nm Narrowband Filters – SII 3nm

    $564.00$2,495.00

    Please call or email before back-ordering Astrodon filters so that we can let you know what the wait will be.

    Back-ordered filters usually ship within 3-6 weeks but sometimes longer.

    If you want the look of Hubble Space Telescope (HST) images, such as the famous “Pillars of Creation” (the Eagle Nebula, Messier 16), then the next filter to consider adding to your collection after H-a and OIII is the SII (es-two) or sulfur filter. The SII filter, like H-a, is a deep red filter near 672 nm. H-a, OIII and SII filters provide that Hubble look for many emission nebula. Again, tri-color narrowband imaging with these three filters can be done with the moon up, so your equipment is not sitting dormant for several weeks.

    Astrodon SII filters have a center bandwidth of 671.6nm
