    Hello Dre71,

    no idea what has been behind your dealer's statement about the filters.
    The Lumicon filters are highly respected by the visual observers, and there is also one red H-Alpha low Lambda pass-filter, used in the astrophotography with the DSLR cameras. The other Lumicon filters, as far as I know, are for the visual observations, and definitely not optimized for the astrophotography.

    Baader, Astronomik, Astrodon and others, offer the CCD filters developed for both the DSLR and CCD astrophotography, and they make them in all sizes for the standard filter wheels and threads.

    I'd address your question to another dealer.

    Best,

    I don't know enough about filters to say whether your dealer is right or wrong.

    I do know that Lumicon filters cost around twice as much as equivalent Baader's.

    I agree with JG, try another dealer.

    Heelo Stevie,

    thanks for the comments.


    The price difference between the both filters in Germany is about 25% at the moment, but it used to be next to nothing some time ago.

    There is a mass of pros nad contras opinions, like in

    Best OIII filter? - Page 2 - Getting Started General Help and Advice - Stargazers Lounge

    I would not worry too much. Most of the AP folks report their pics filtered with Astronomik or Baader, and the richies, they take the full sized complete sets of the Astrodon filters.

    Best,

    I have the Lumicon OIII in the 1.25" format. Can't say enough good things about it. No idea how it compares to other brands, but I believe it is "one of" the best.

    Well in theory the threading on filters should be standardized, but I know some have complained of variations between brands. Personally, I have both a 2 inch Orion 2 inch UHC and O-III. I find that I have difficulty screwing them into ES 82 18mm and 24mm EPs occasionally. But no difficulty screwing them into the Orion 1.25 to 2 inch twist-lock adapter when using the 1.25 EPs. I have also heard of others having some issue with the threading on the Orion fillters. I do have a 2 inch Baader Hydrogen-Beta, and don't have any problems screwing it into any EP or accessory. So honestly, I don't see why they would tell you that you had to have a Lumicon. Sounds like they might have been pushing the more expensive brand. I don't believe you would be disappointed with the Baader version.

    As far as differences, I think if you look at the specifications for various brands there are differences regarding passbands, and apparently some do allow a broader swath of light to pass through. But, how much difference you would actually see visually between them can be affected by the individual observer. I know at my age, 58, I don't see some of the subtleties that I used to when I was younger. Therefore, for me, I don't think I would be able to detect much if any difference between brands. I like the ones I have, and have no plans to change them out for Lumicon.

    Hello Stevie,

    with the increasing demand on the market for the CCD-grade filters, the Baader's mass production of the filters, even with the traditional Zeiss expensive quality standards, may allow for prices beating anything else on the market.
    Baader is also well known for their precisely machined filter threads, matching without any problems with all EPs.

    However, as with anything, Baader offers some unsurpassed filters, like the OIII (CCD) 8.5nm both for visual and AP, and their interferometric RGB (CCD) set, Astronomik has the excellent UHC filter, Astrodon has their extremely narrow-band true balanced filters, Lumicon has its legendary visual H-Beta filter (lots of people have seen the Horsehead Nebula the very first time through this filter and they will never forget it), etc.

    Best,

    I managed to get a hold of this one recently JG

    Filter Deep Sky 1.25in - Standard & Specific Telescope Filters

    It's a nice little filter. I managed to see some traces of the California nebula a few weeks ago, and the Veil is excellent. Looking forward to using it on the Rosette. I'm seriously thinking of investing in a 2" for the 27mm Panoptic.

    Hello Stevie,

    thanks for the update on the Lumicon web site.
    Not sure, if Lumicon has made a technology remake, but below are the curves of the older Lumicin deep sky filter

    Astronomical filter curves

    Looking like a good choice for the visual observations, even if the purists would worry about the filter leakage in 400nm - 430nm.

    Looking forward to more of your reports on using this filter, as it helps all of us when making a purchase decission.
    Best,
