    Default New Neodymium Filter



    I just purchased a new Baader Neodymium filter from Agena Astro. I've never used one of these filters, but the advertising was just great.

    Baader advertises that this filter is useful on Jupiter's GRS, Mars Ice caps, as well as globular clusters. Three of my favorite things in one filter. It seems to me that it may also have some use on Cassini's division and some emmision nebulae. If it can do half of this, it will be a useful new addition to my EP case. This also represents a milestone for me. I typically buy the cheapest selection available. Maybe a Baader EP will be next.

    Hello Sixfalls,

    all Neodymium filters are the contrast enhancement filters due to the multiple passbands of the Neodymium doped glass substrate.
    The Baader Moon and SkyGlow Neodymium filter has a very good RGB colors balance, and the UV/IR cut.

    According to my observing sessions, this filter increases the contrast of some features on the planets,
    it increases the color contrast of the stars in the open clusters, it increases the color contrast in the double stars.
    and sometimes it increases the contrast of some galaxies.
    It does not work on the diffuse emission nebulae, and I don't take it on the globular clusters.

    I am mostly using this filter on the galaxies,

    Well JG, it sounds like I will like this filter; but I might want to make it a duo with a quality UHC. Is that about right?

    Hello Sixfalls,

    yes, the UHC filters are very helpful on the galactic nebulae, and the Astronomik UHC filters I am using, are also great to reveal the spiral structure and the star birth (HII, OIII) clouds in the Triangulum galaxy, even through my 6" achro.

    Best,

    I have used this filter for two years. It is the best filter for Jupiter out of all I tried, it enhances colors and contrast of belts and GRS. I got the filter just for that. But then I also discovered that it does help to pull faint globular clusters from LP areas, like city light domes, and it helps on occasion to detect a faint face-on galaxy or even a comet.

    For Mars and Saturn I actually prefer Baader Contrast Booster. Baader makes good quality filters and I learn over the years not to compromise on filters quality.

    No. ND filter just dims the light across the spectrum. Neodymium passes certain wavelengths and blocks others. It is more like a very broadband nebula filter.

    Thanks. I'll check out the contrast booster by Baader as well. I have really learned a lesson on filter quality. I don't want to trash a brand, but I have a cheap UHC, that is just about useless. I've been shopping Baader, Lumicon, and with JG's new recomendation, I'll check out Astronomik. Someone else here recomended that brand to me not long ago it seems.

    Re: Astronomik UHC filter

    This UHC filter is regarded as a filter wit medium passband widths, so it is not as narrow as the Orion Ultrablock.
    I often use it as an all purpose filter for the nebulae, still passing enough stars llights not to get lost on my way,
    and thanks to a wide passband in red, the red Miras and the deep red carbon stars are still bright with a high color contrast.

    There is no UHC filter, which would replace the narrow passband OIII and H-Beta filters on their respective jobs,
    but I love to mount the UHC filters on my binoculars, and to chase the nebulae.
    The UHC filter is always in the filter wheel on my 6" refractor

    I am a Lumicon guy as far as nebula filter goes. Can't go wrong with Astronomik either but they don't have as strong presence in US.
