Just getting back into using my telescope and have an old celestron #58 filter that really helped with tbe moon. I have a small budget so found a good deal on mostly Tiffen filters with 3 old Celesteons. Now I have almost all (missing #47 and #82A). Now I see they have nebula filters so I will need to get a few but they are pricey. To bad it's going to be awhile before I can try these out as crappy weather is moving in. I have never enjoyed my scope as much as I have over the last few weeks and it should get better wih these filters.

Nice haul! As someone who used to do a lot of planet sketching, I've always been an advocate of having a comprehensive set of color filters. They can be very helpful when doing long, detailed sketches over long periods. And individually they aren't expensive so it's easy to build a collection piecemeal without ever breaking the bank. Just know that a lot of the enhancements you see will be subtle, and like any piece of gear, color filters have a bit of a learning curve. Swapping out filters while sketching is a really good way to get a feel for what they can do. 

 

What I like to do is keep all of my 1.25" filters organized and labeled in a Plano plastic case from Home Depot with simple foam inserts. Makes it easy to locate the filter I need quickly in the dark. It's cheap and makes life easy.

I iike that idea of storage, and my next question was going to be what is best way to store as most mine do not have indivdual hardcases. Does the foam seem to cause any problems over time? I know some foam breaks down over time and don't want to ruin the lenses.

I've had them in that case for about 7 years and haven't run into any issues so far.

People often talk down color filters, and I suppose for the beginner that's understandable. However, they can be useful for planetary and lunar observing. Subtle, but useful. I should have tried some on Venus when it was around.

Why would people talk down color filters? With the one I had I noticed a difference when I used it. Now I probably have some I don't need but for $5.50 each I'd rather have it then not. I am still looking for a #47 and #82A

I think #82A is one of my top 3 most indispensable filters, and I would highly recommend prioritizing that one. #47 is very aggressive and a limited use filter, but 82A is enormously flexible.

I have seen 82A as being really good. Just need to find one.

I was able to briefly try out some of my new filters,WOW!!! #21 does a really nice job on the moon. I fried ND9 also and it did well also but I think 6 or even 3 may have been been better choice but did not try tonight. I tried my polarizer and I am not sure it really helped with the double ouble in Lyre. It js possible I may not be using enough magnafication but the moon is almost full so I sky is pretty bright. So glad I picked all these up, and for anyone who is reading this and on the fence for buying color filters, DO IT. Find nice vintage ones, they really help.

I'm not huge into filters of any kind, but I have three Meades I can comment on.

 

1. Meade ND96 moon filter has 13% transmission. I don't use it in my personal viewing, as I use high magnification to greatly reduce brightness. However, when I zoom out to show others the full moon or nearly full moon, I use it, or someone complains the brightness hurts their eyes. 

 

2. Light yellow #8. It's a very pale filter with a color shift so slight, you can hardly notice it in my refractor. My scope shows far less CA than it's supposed to show, and this filter reduces it even more, to where it's just not noticeable unless you try hard to see it. It also can give a slightly improved view of Saturn on some nights. I try it, once in a while, on Venus too.

 

3. Light blue #82A. I try this one on the moon, Saturn and Venus and it never hurts the view. Sometimes, it might even be a little better than my preferred natural view. 

 

I've also experimented with stacking the #8 and #82A on Venus.

I enjoying views of tbe moon with and without filters, just depends on what I want to do for viewing. Cirrently do not have any planets to see so it's the moon and some stars atm. I am trying like heck to see M57 but I have no idea if i've seen it yet, just not sure how it would look througb a 6' scooe and what magnification you need to know you seen it.

Hi Moonbiter,

 

and congratulations to the stack of the Tiffens.

Herewith, you will realy be biting in the finest details on the Moon a planets.

 

On a side line, as the astronomy filters are not enough, I have started to repurpose the special filters from the microscopes accessories.

 

Let us know, how your Tiffens will be doing,
JG

Filters useful in Astronomy:

 

Colored Filters for Moon and planets:

Reds: 29, 25, 23A

Oranges: 21

Yellows: 15, 12, 8

Greens: 11, 56, 58

Blues: 38A, 80A, 82A

Violets: 47

Magenta: 30

Specialty: Baader Moon & Sky Glow (Jupiter), Baader Contrast Booster (Mars)

Neutral density: 13% (full or near full moon), 25% (half full to gibbous), 50% (crescent to half full)

Polarizing: Single (for sharpening), Variable (to replace ND filters)

 

Nebula filters:

Broadband--small enhancement

Narrowband (UHC)--large improvement

O-III line filter--super enhancement on specific objects

H-ß line filter--super enhancement on specific objects.

Optica b/c filters are my favorites.  Here are mostly complete sets in 1.25" and .965" including interference filters and ND.  It's taken a long time to accumulate them.  They are extremely well made.  The interference filters have low transmission rates compared to modern filters.  There are also IR and true UV and polarizing filters.  Optica b/c also published a fine book to accompany their filters that is loaded with good information on using filters.

And you have still place left for more than a dozen of other filters,

Thank you.  Most of those empty slots have been filled.  Oddly enough, the only one I can't seem to find is the light red.  That one should be easy, but it's not.  One other interesting thing about the Opticas is that the 1.25" and .965" use the same size glass - only the cells are different.

You don’t have leopard or zebra pattern.  You really are just wasting time if you haven’t gotten a reasonable collection of animal print filters for planetary viewing.

You're forgetting plaid. You can only use it with really FAST optical systems though.

I just put a Ronchi screen over the filter for a zebra effect.  As for leopards, I have plenty of dust on my eyepieces that provide for that.

I can't see any Tarten either.

Moonbiter, try to find an #82A or even a deep violet (is there one ?). The point is that the blue wavelengths  ( ~ 500 =nm) are shorter than green and red, and if you have a scope with exquisite optics this may give better resolution on the moon. Particularly if its a newtonian, classical cassegrain, or one of the unicorn premium Maksutovs. 

 

If you have a Mewlon, Vixen VMC or refractor it may, or may not help. SCT's probably won't show any difference.

 

@Deathwarpedup, you mean "tartan", surely ?

Weirdly, both tartan and tarten seem to work on a google search
