    Default Nebular Filters for Binoculars - frequently asked Questions



    Hello friends of binocular astronomy,

    this post is about to share my experience with using the nebular filters on binoculars, and to address some frequently asked questions.

    a) Nebular filters make sense under light polluted skies, only.
    Correct, here are such filters "must to have".
    However having them, you can watch lots of the DSOs even under the Moon light!
    Moreover, the narrow band nebular filters also dim the light of the stars embedded in some nebulas (Clamshell Nebula Sh2-142 in the NGC 7380, and the Tadpole Nebula Sh2-236 / IC 410 in NGC 1893), increasing the nebular contrast in the open clusters even under clear skies.

    b) Nebular filters do not add the value people expect. Correct with the cheap filters.
    Admitted, I have also paid for the lessons learned. What matters here, is the transmittance (should be more than 90%), and the narrow band around the emission lines. Such high-end filters reveal amazing details in the nebulas, and make many more nebulas visible. However, they may become more expensive than the binocular.

    c) Nebular filters do their job on 6incher and larger scopes. With the Horse Head nebula you'll need a 16incher or even a larger scope, anyway.
    However, some people hold the H-Beta filters in front of their eyes to see the California Nebula and the Barnard Loop without any binocular or scope. The maximum benefit of the nebular filters is expected with any optics giving large exit pupils: 6 to 7mm with small binoculars, down to 4mm with big binoculars.

    I am currently using the following nebular filters with binoculars:
    UHC (Astronomik): Great Orion Nebula, Lagoon, Omega, Dumbbell, and other bright nebulas, resolve some detail.
    OIII (8.5nm Baader): Amazing detail on North America, Cirrus, and on Little Dumbbell. Excellent on most of the planetary nebulas, see also the thread "Hunting Planetary Nebulas with Binoculars".
    H-Beta (Astronomik): to be used in this season on hunting the Sharpless nebulas, and working out details on the Great Orion Nebula.
    Blue(RGB Baader): this is a very broad band pass filter, transmitting 400nm over H-Beta up to the OIII lines. In this sense, not a real nebular filter. However helpful on some bright nebulas surrounded with the dark nebulas, like the Butterfly Nebula, the North America - Pelican Complex, and the Elephant Trunk Nebula, in wide field binoculars under my skies.

    Hoping to have helped anybody considering the nebular filters,

    JG

    If I could ask, please - how do you mount the filters on the binos? I never saw a pair with filter threads. Are they in front of the lens or on the eyepieces? And do you use two of the filters - one for each eye? What is the benefit using two very expensive filters with binoculars vs. using just one with a telescope?
    Thanks,

    Hello Mplanet62,

    most of the Garrett's Optical marine binoculars have threads in the eyepiece barrells to screw in the 1.25" filters.

    With my old 25x100FB I am using rubber eyecups (40mm diam) to fasten the filters. With Leica Ultravid, I can push in the slim filters, as those made by Astronomik.

    Attached find please pics for illustration.

    Where could you find filters for binoculars? I only found solar filters and those that are meant for a telescope. I have the 10x50 Celestron Nature View Porro Prism binos, any help would be great!

    Hello Envirolutionary,

    Fujinon offers dedicated UHC filters to be mounted into the eyepiece barrells of their binoculars.
    Some Garrett's Signature binoculars, like my 15x85, have 1.25" threads in the eyepiece barrells to screw in the nebular filters.
    With the other binoculars without the threads, I fasten the filters in the eyepiece barrells with help of added rubber eyecups, like shown in the post above (05-14-2011).
    In all cases, the filters are between the eye lens of the binocular and your eyes.

    Regarding your 10x50, check out if the eyepiece barrells have sufficient inner diameter ( slightly more than 1.25"), and a sufficient eye relief (16mm as a minimum required) to push-in and fasten the filters.
