Sun on May 24

[John W]

May 24. It has been cloudy here for days in central Victoria. Managed these two pics of the sun today around noon - sky conditions were poor.
Both pics are single exposures thru a Lunt 100 Ha scope using a Canon 550d camera. The orange pic was exposed for the surface details while the yellow pic was exposed for the prominence on the W limb. The sunspot is AR12546. Thanks for viewing.

Thanks for posting John. A lot of cloud here and your pic might be my last chance to see 12546!

Well done John, during extensive cloud cover across Victoria. Most impressed with the prominence image. Regards, Arthur.

What do you mean by "exposed for"?
"The orange pic was exposed for the surface details while the yellow pic was exposed for the prominence on the W limb. "

I'm only just starting photo-observing the sun with my 500mm fixed f/6.3 lens with ND5 filter. I do get faint surface structure during processing but not much and I'm wondering whether ND3.8 would give me more.

And of course: it would be yummi to catch the prominences if I get lucky.

Reply to Silv,
My photographs are taken in a very different way to what you are trying. My telescope has a special H alpha filter so it is taking shots in a very narrow bandwidth at a single wavelength. What you are doing is using a very very wide bandwidth - you will never get any pics of the prominences or surface detail with what you are doing. Suggest you get some books on the subject.
Cheers, John W.

Cheers for the hint :)
