Op here. Now I have some time to address this question.
>The majority of your photos, much to my bafflement, depict all of the planets in a red light. I didn't really notice with Jupiter, but Saturn has always been depicted as being this off-pale blue, however in your photo it is noticeably red.
The Red hue may be due to my adjusting the white balance so it looks more natural to my eyes, but I usually do an auto adjustment and try to make the color as natural as possible. I will be honest, I've never noticed a pronounced red hue in my photos, except for a few.
As for Saturn, I have not noticed that NASA has ever depicted it as a pale blue. Pics related are Saturn pictures i found very quickly on Wikipedia. Are you sure you aren't referring to Uranus or Neptune (also in pic related)? Those are consistently depicted, and visually appear to be, pale blue-green. I've also included here my own pictures of Uranus and Neptune. From my viewing, even visually (ie not with a camera) Saturn has always appeared pale yellow.
The last pic related is maybe the one you are thinking of? It was taken in False color from Voyager 1, found here: >https://nssdc.gsfc.nasa.gov/photo_gallery/photogallery-saturn.html
Here is part of NASA's Description of the photo, found here: >https://nssdc.gsfc.nasa.gov/photo_gallery/caption/saturn_false.txt
<This image of Saturn, taken by the Voyager 1 spacecraft on Oct. 18,
1980, was color-enhanced to increase the visibility of large, bright
features in Saturn's North Temperate Belt. โฆ
<Three separate Voyager images taken through ultraviolet, green and
violet filters were used to construct this blue, green and red color
composite of Saturn. The lower edge of the rings were "clipped" due to a
slight drift of the spacecraft. Color spots in the rings are an artifact
of image processing.
This leads to a discussion of various photographic filters and their uses in astrophotography. Color filters, like the ones at this link:
>https://www.telescope.com/Orion/Accessories/Telescope-Eyepiece-Filters/125-Orion-Basic-Set-of-Four-Color-Filters/rc/2160/pc/-1/c/3/sc/48/p/99590.uts ,
are used primarily visually to bring out various details in planets (ie Jupiter's Cloud bands, Mars' polar caps, etc) and are not really used for photography, though they can be. I did not use any color filters in my planetary photos, however I may have used a light pollution filter designed for astrophotography, seen here:
>https://www.telescope.com/Accessories/Telescope-Eyepiece-Filters/125-Orion-SkyGlow-Astrophotography-Filter/pc/-1/c/3/sc/48/p/5559.uts?ensembleId=37 .
This is due to living in a severly light polluted area, and this helps to darken the background sky. It should transmit colors naturally, though I concede that it may be the source of the red tinge you see. I don't recall precisely which pictures i used the filter with.
There are other filter sets used for Astrophotography that are very useful for studying astronomical objects, and I will discuss them each below. Each of these sets are used with a Monochrome camera. Essentially you take multiple B/W images through each filter, and assign a color channel to each layer. Then you stack the images to get a full color image. You may assign whatever color to each layer that you want, and vary it's intensity. This means that a single object can be depicted in many ways, with many different colors, and still be accurate depictions. This leads to some remarkable photographs. I will discuss the different filter sets in the next post with more pictures.
