Hi,

the suns disk at various wavelengths....

Hope it is interesting...

Wavelengths are 94,131,171,193,211,304,335,1600,1700 and 4500

ang. respectively.

Gordon.... Happy New Year

Hi Gordon, would like a chance to really look at the images. Is it possible you could adjust the rate of change on pics please, would like a few seconds on each one or maybe you could post the separate images.

Thanks

David

Hi David..

I knew that when I put it all together it was too fast.

I have dumped the pics now.

If you save the animation to your desk top,

you may be able to dissect using GIF animator.

Cheers Gordon.

Thanks for that tip Gordon love the images. Gif 3 & 6 outstanding.

Are they real colours? I am asking this as they looks real but none of the wavelengths are within visible lights' range 380-750 nm.

HI Jinstan,

in a way ,you are correct,but also not.Sunlight is complex.

The spectrophotographers would tell you that.

H alpha ,for example needs highly specialised filter systems

to isolate in this narrow band.

However,the other pics are derived from,as,for example, in the first instance

Fe. That is the Fe 94 spectrum.

Hey, this is very specialised and out of the range, as yet ,of

most of us amateurs. The results are intriguing though,and I thought

they would be interesting.

Hello Gordon,

I love these pictures, they are really nice! May I ask how you went about acheiving these? I have no knowledge of solar photography but after seeing these it opens up a new avenue of what to image.

[simplybob]

Wow I'm really liking these! I too would like some insight into how you took these pictures?

Looks like they were taken by SOHO...

Great animation,

Wonder if you can answer a question about Halpha Solar viewing. My friend just obtained a Lunt Ha Double Stacked (60mm) Solar scope. While viewing the sun through it and observing sun spots and flares I noticed an effect which appeared like small black pinpoints flashing all over the image. I put my eye to the eyepiece several times to confirm I wasn't imagining this. I have never noticed this before and wonder if you have any idea what this might be? James

Neat animation!

Hi James,

I have not seen an effect like this.I cannot explain it.

Sorry.
