Eclipse - Brisbane - surface detail?

[davewaldo]

Hi Everyone,

Just finished processing my first ever image of the sun. Just a small eclipse from Brisbane, but I did get lucky with the clouds.

This was also my first time imaging with my recently accquired C8. Overall I'm very happy with the results. It seems I've even captured a bit of surface detail (not sure what these are called...) in the lower left.

I'd love to get some feedback. Is the grain from my camera (noise) or is it detail of the sun?

Details: C8 (masked to 130mm) with f6.3 focal reducer, on Vixen SP mount, Canon 20D (not modded), 1/500sec @ ISO200 with Baader Solar film. Stack of 3 exposures (which helped bring out detail).

Great image! Nice to see some surface detail using solar film. Can't say I've seen that before.

Great image of the eclipse David

It's awesome that you were able to capture that surface detail.

Well done. It looks great with the active region in there.

I love seeing what members have captured from each designation. Great pic, interesting with the detail too.

Thanks everyone for the positve comments!

So is the grainyness actually the sun surface or is it caused by something else?

What I love is the lumps and bumps on the edge of the moon.
You kind of expect it to be smooth, but of course it isn't.
That's a nice sharp image.

Dave -

That "grainyness" at the 8 o'clock position in your photo is indeed an active region on the sun's 'surface': decaying sunspot AR982, moving towards the limb. Nice work!
