    Question Lumicon filters Vs ????????



    How do Lumicon light pollution filters compare to other brands of filters in quality? I see Televue and quite a few others make these type filters. There is quite a few to pick from. I do not want to spend a fortune but want a good quality filters.

    Light pollution filters can vary and many do not put a lot of confidence in them...and after all they are quite expensive to buy.
    Have a read of this article first, I hope it will help ..Dave Knisely on Light Pollution Filters

    I am with Declan on this one ...Also , Most guys that buy filters still have them but have only used them once or twice and they just take up space in there equipment case ..Unless it is one of the anti-fringing filters that stays on a achromat refractor ..

    Hi. Good advice from the folks already. Excellent writeup from David Knisely. I have the Lumicon UHC and O-III filters. They work but it isn't a large difference. A little more contrast and detail. I noticed a little color with M42 that I didn't see without the filter. I haven't tried any other filters so I can't compare them to other brands. Filters are kind of expensive for the benefit returned but there is a small benefit. Just my opinion based on my equipment and viewing conditions.

    Keep in mind that narowband filters like O-III and UHC will make the view too dark unless you have enough aperture, nothing under 8 inches and 8 inches is borderline.

    Just my opinion based on seeing them in use on telescopes smaller than mine (12 inch).

    Hello Big Dipper,

    I am not only a bino freak, but also a filter freak.

    The filters I am regularly using are:

    UHC Astronomik: narrow band ultra high contrast nebular filter, a little bit wider than UHC Lumicon, but more light on H-Alpha line: great on M8, M42, ...
    UHC-S Baader: broad-band nebular filter: useful on some galaxies like M33, etc
    H-Beta visual Astronomik: a little bit wider than H-Beta Lumicon, not yet tested
    OIII 8.5nm Baader: possibly the best visual OIII filter on the market: great on nebulas North America, Cirrus, Pacman, etc , and on the planetary nebulas
    #47 violett transmitting filter TS: blocks the H-Beta, OIII through red
    blue (RGB) Baader: transmitts blue light 400nm through OIII: useful to dim the yellow Sodium/Natrium street light emission lines red to green
    Sky Glow Neodymium Baader: color contrast increasing filter, dims the Natrium emission lines: nice on binaries, and on some galaxies (M81)

    The ARO - Filter Research

    Some of the filters may show aging of the stacked multilayers. Other may suffer from dew on cold nights. That's why you should carefully consider what you really want and expect, before buying those expensive filters.

    Thanks for all the information. I will probally get the H-Beta, OIII, UHC filters for my scope. It is an Orion XX12i 4.9. I really like the scope. Need to add a few more things down the road. Next major change will be a Moonlite focuser not to far in the future. Thanks again
