Hi Everyone,

Just finished processing my first ever image of the sun. :D 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...:sadeyes:) 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.

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!
