Description This is the updated, final(?) version of this piece:


One of two bright stars in the constellation Gemini, Castor is actually a multi-star system  that is believed to contain six solar bodies.  Composed of three separate binary systems, Castor is the 20th brightest "star" in our night sky.
To get to know the system a little better, we'll start by seeing how the stars are labeled:
Castor A: A binary system composed of a hot, bluish-white A-type star (Aa) and a coolor M-type red dwarf (Ab)
Castor B: Another A-M binary star pair (Ba and Bb)
Castor C: A pair of cool red dwarf stars with a fast orbit of about a day around each other (Ca and Cb).
All of the red dwarf stars in the Castor system (Ca, Cb, Ab, Bb) are classified as Flare Stars , and you can see a giant solar flare in progress on the the star in the foreground.
Here, the camera is zoomed in on Castor Ca, with its twin Cb in the foreground.  This pair is likely orbiting around the other A and B systems, but with a period of several thousand years.  You can see the other two systems, B and A, as you move down the screen.  They would likely appear to be further away or fainter than this from the perspective of Ca, but I could find no good reference images for this system and had to play it by ear a bit.
This is an entry for Space-Revived 's Chromatic Contest:
Space Art Contest: Chromatic!Space-Revived Presents... THE CHROMATIC CONTEST
At long last, the new Chromatic Contest arrives, open to all members of Space-Revived!
The theme is completely open to your imagination, with a twist: you must use only ONE OR TWO COLOURS in your space artwork. Your space art may represent anything you can imagine, but the most important thing is to champion your choice of colour.

Rules:
• You must be a member of Space-Revived to participate. However, everyone is welcome to join!
• Submit your work to our Chromatic folder.
• State in your description that the image was made for the Chromatic contest with a link to this journal.
• Two entries per deviant allowed, but only one can win.
• All entries must be created after October 14

The colors I chose are orange and purple.

Hi from ProjectComment !

This is such a beautiful painting and close-up! Orange and purple is a hard combination to work with, and you've nailed it .

I really like your placement of the stars, the zig-zag positions make the system look more varied and natural, as it's extremely rare for stars in a system to be perfectly aligned. I also like how you decreased the luminosity effects of the stars as they get further from the foreground, and kept the rest of the piece clear of major landmarks to keep the audience's attention focused on the main stars. Lastly, the solar flare and sunspots make the closest star look active and dynamic, while the darker orange patches convey the impression of significant temperature variability on its surface.

The close-up star looks kind of organic to me, mainly because of the blending and blurring effects on the flares. When I look at photos of the sun's flares, I get the impression of sharpness and high contrast between the flares and outer space. While there is some 'blur', it's mainly due to the radiating from the flares rather than from the flares themselves. Because of the blending/blurring, the central star looks more like an artist's rendition of the star than a photo of a star (which it is). That said, this doesn't detract from the quality of your painting.

Hope this helps, and keep up the excellent work!
& Best of luck in the contest!

Hi bluediscord !  Thanks for taking the time to comment

I have no idea how to make photorealistic flames without better software (e.g. AfterEffects), so I'm glad that the painted look worked out OK.  It's not my usual art style, but I think I'm going to have to try smudge painting more in the future.  That said, I may experiment with less blurring and blending next time -- see if I *can* get that more realistic feel without resorting to fractal noise filters and the like.

Lively.
No other word first comes to mind when I see this. Seeing the star close up as this, it is nothing short of awe-inspiring this restless giant is only the speck of a dot in the night sky to the naked eye. The alignment of the rest of the system, increasingly distant and trailing away to transition into the myriad stars, not only gives a feeling of depth but also the impression the nearest star is the spearhead of a much greater whole.

Thank you for the mention, 'tis a pleasure. Seeing this picture mature has been like I imagine an actual space traveller might experience the last leg of the journey to Castor, seeing the nearest star slowly growing from a bright disc against the dark, the hint of a flare, to a blazing star in all its splendour, reaching out a thoughtless misty limb in a warm welcome...

Thank you for the kind comment   I'm really, truly pleased with how this one came out, and I owe that in part to your willingness to let me see it through your eyes for a time.

Thank you.  Castor is a really amazing system, and I enjoyed sharing it with people who may not have heard of it before

Not bad, not bad at all, what program did you use?

Planetrix In reply to Archange1Michael [2017-11-24 20:16:53 +0000 UTC]

Thanks! This was done entirely in GIMP; the flames were painted with a soft round brush and the smudge tool.
