    .. aemann, that chart is absolutely fantastic. It's going straight into my EP case.

    Also thank you for that direct link to the file waiting to be approved.. I had no idea there was a completely isolated management screen/moderation queue just for the downloads subforum, and I'm willing to bet most of the other mods didn't know this either. I'll bring this point to light..

    My pleasure! I hope others find it useful - I can now see what filters I need without spending silly money on ones that won't get used often. I thought that moderator queue was how it was supposed to be...!

    Just checked the prices of UHC and O-III filters - yikes! They might have to wait a while! Are they really effective or is it a marginal effect? My site is pretty dark with next to no light pollution, so would I really benefit?

    The UHC and OIII have been very useful for me at least. On occasion it has been the difference between just seeing a group of stars and seeing the nebulosity among those stars. They are nice to have, although I wouldn't go as far as saying that everyone should run out and get them immediately.
    The UHC and OIII seem to compliment each other well and I don't really see them in terms of one over the other personally. I don't own any planetary filters, so no comment there.

    Rich,

    I did a fair amount of research when considering whether to add a nebula filter to the various filters that came with the Zummell EP and filter set. I settled on a UHC filter rather than an OIII in part because of the price and in part because they seemed to have a similar function. Nevertheless, because nebulas seemed to actually become less visible, after further reading that touted the OIII filter's functionality, I figured go for the OIII. I put it on to various lenses looking through my Meade 826 8" Newtonian. At this point, for more than the cost of Kimberlyb's $80 10" Dob, I got a black-out screen.

    Comments and suggestions, please,
    Mokudo

    Keep in mind ...This is lumicon's recomendations for the most detail ...I am sure there are other filters out there and the results might vary from scope to scope due to aperture and quality ....
    I've gotta say that though the founder of Lumicon, Dr. Jack Marling, is a person I've worked with and consider a friend, this list is PRETTY simplistic. I wonder if it is a "new" one that the current owners of Lumicon have compiled, or if it's originally one that Jack Marling himself posted--does anybody know? Lumicon is now owned by the corporate ownership that also runs Scope City.

    I was groovin' along with the list, very impressed with the part about the planets...but when I got to the deep sky objects, I stopped dead...because one by one, I either disagreed, or felt that the "best one" is not a really meaningful and possible choice for all viewers, all scopes, and for ALL aspects of these remarkably varied objects.

    In fact, though I've seen other compiled lists of recommended filters, including what is perhaps the most celebrated one, for emission nebulae (by David Knisely), I feel that it's important that one not just STOP at any single filter recommendation, but check the object with all the filters used for deep sky enhancement; at the very least, the LPR, UHC, and OIII types.

    The reason is that when you change magnification (& therefore exit pupil) you vary about everything you can see with any of the filters. Sometimes the LPR type (which might barely seem to do much of anything visually, at low power) will have an AMAZING improvement--at high power! And the opposite is true of the OIII--at high power, pfft. Most things except tiny planetaries are hard to see at super high power; at low to medium-low (in almost any scope!) that filter SINGS.

    And for every one of the filters *and nebula types* there are exceptions to what I've suggested, above.

    If you can handle an expenditure, BUY THOSE THREE TYPES. Then you are set and you can have a ton of fun experimenting--your results might be unique to your situation, and differ from the "advice of authority figures".

    (Uh...by the same token I advise you to be skeptical of MY advice and not just take it for granted!)

    Yours,
    Steve W/8HHaggis
