Hi All,

As I saw the list of the 2016 David Malin Award winners last night,
and congratulate them all heartily,
I’m thinking that the spectacularly colourful images of star spectra
could surely merit featuring for next year…?

Could be a single visual, or a composition or collage?
Could be as time-lapsed sequences of an 'event' too?
(either just animated images or side-by-side with animated graphs)
In these categories:
Deep sky
Junior
Solar System
Animated scientific
Animated aesthetic

What do you think?
Regards
Sol

Not sure what you mean. Can you clarify what you are suggesting?

Do you mean images that highlight different coloured stars like the Jewel Box for example? (I must say I have yet to see an excellent Jewel Box image, it seems very elusive).

Greg.

Thanks, Greg. Here’s to hopefully clarify…

Just found for you a couple of examples (prism or use a grating like a filter). The astrophotographers’ technical skills and illustrative creativity surely can make something out of numerous nuggets of gems.

The Hyades spectra, in http://www.skyandtelescope.com/astronomy-equipment/the-spectral-types-of-stars/

Sharing some ideas here, for bright enough objects depending on the equipment:

Like a star wheel, how about selecting out: Canopus, Achernar, Alpha Cent. as their spectra spin.
Something near the celestial north horizon wheeling their spectra like rays.
Something has just got to be done about the ‘spectral gem’ gamma Vel., and eta Car. A lot of people in the northern hem. cannot even see these, or have not, like, ever.
[The Jewel Box, where bright enough and at certain orientation might just show something special. Good idea, Greg.]
A spectral array of the planets, like earlier this year when we had several up and very bright.
A composition or collage, say of all major star classes or of Wolf Rayets, but with more artistry than blocky strips (at the same time preserving the scientific data).
Terrestrially, I wonder what a lava flow might show. Or an active volcano. Or sunlight reflection off some water or waterfall or an observatory dome.
Spectral animation of part of the sun spectra that’s changing relatively rapidly.
Spectral animation of a comet.
Spectral animation of a planet moving relative to a star or cluster.
Spectral animation of a stellar event, maybe revolving binaries or a nova or SN.


Some of these may not work. Some will. Where there’s a will.
