USING FILTERS FOR LUNAR/PLANETARY OBSERVATION
by WilliamPaolini
1. Overview For the vast majority of my astronomical observing life, over 50 years, I have never used filters of any kind for planets or otherwise. But after half a century of reading the extraordinary claims by manufacturers and observing organizations alike about the many benefits of the various color...

Re: USING FILTERS FOR LUNAR/PLANETARY OBSERVATION
I also have never been a big filter guy, with the exception of the Moon and maybe Mars.
Will have to play around with the ones I currently have.

Re: USING FILTERS FOR LUNAR/PLANETARY OBSERVATION
My all time favorites are Baader Moon and Sky glow and Baader Contrast Booster individually or stacked together. They work great on Jupiter, Mars and to a lesser degree Saturn. For Saturn and crescent Moon may favorite is Orange #21, for full Moon - Green #58. I also has good results with Red #23A and #25 on Mars.

I already tried the Baader M&S + 82A on the Moon, not a combination I would have thought of myself.

The Wratten #8 yellow (also called "minus blue" in some photographic or scientific circles) is very handy for daytime images of the moon, as it will darken the blue sky, and may increase the contrast of lunar surface details. It is also useful for increasing the contrast in the maria on Mars.
The Wratten #11 yellow/green also can increase contrast on the moon, and as a bonus may reduce the chromatic aberration of apochromatic refractor telescopes as you approach the lunar limbs.
The Wratten #15 deep yellow can be used to bring out Martian surface features, and the polar ice caps. It can also be used to enhance the orange and red features, bands, and festoons on Jupiter and Saturn.
The Wratten #82A light blue works well on Jupiter, Mars, Saturn, and the moon. It's pale blue color enhances areas of low contrast and avoids significant reduction of overall light level at the same time. And here is another bonus. Some users report seeing more details face-on spiral galaxy arms and galactic structure, such as on M51.
Thanks for your great article Bill, and I hope that I have added some useful information too.

However over time, I found that these are the filters that I find most useful:
The variable polarizing filter is great for reducing the incoming light level from the moon on some nights and may reducing "blooming" from some of the brighter surface objects in your captures. And, it works well on some nights with Jupiter and Saturn.

these are very nice sets of the filters, reminding my sets of filters for the classic photography in past.
Since those times, most of my photography filters are gone, keeping the pol filters, the neutral graduals, some KR to kill the skylight, and the Neodymium color contrast enhancers - still useful for digital as well.
Best,
JG
