Thanks for your kind compliments, Peter, Rainer, Eric, James, Arne, Frank, Terry, and Franco

James, I have read about Ellerman Bombs but am still not too sure how to identify one with certainty :)

Thanks Lou and Jack for your kind compliments.

My images tend to be soft and flurry because I like them that way and also because, at this point, I am not prepared to spend too much time on it.

I have received much support and also suggestions to improve. With his permission I am posting 2 other versions done by Eric. These 2 images show more details compared to mine. Do enjoy them and give your comments as well:

A special thanks to Eric for taking time to improve the images and give them other perspectives.

Looks great, Alfred. Seems to see you've got that setup working very well!

Regarding the processed images; it's always gonna be a matter of personal taste really. Out of the three, the first one in the post above is probably my favorite (although the other two are excellent as well).

Ellerman Bombs are tiny micro-flares. Still much bigger by many magnitudes compared to any nuclear detonation on Earth.

Alfred:
Jochen is right, it is a matter of personal taste the way we all process our astronmical images.
Thanks for letting me experiment with your original fine image.
Best regards,
Eric.

Great hires, Alfred, congrats!
I imaged the sun about the same day 11:00am UTC+3 with my C11, but no flare was seen

Very, very nice indeed, Alfred. Beautiful image. The reprocessed images by Eric are great too. Lots of fine details in that spicule field.

Thanks Jochen, James, Alexandra, Raf, Marios, Eric, Franco, Leo and Stu for your kind comment and sharing your thoughts about the different renditions of the image. Thanks for your support for SPOD.

Jochen - I prefer soft images but sometimes I add some more sharpening, like those done by Eric to bring out more details.

James - Thanks for the concise description of Ellerman Bombs, it remains us again about the tremendous energy the Sun has.

Alexandra - the Sun is really a beautiful living thing which amazes us with astonishing features. I have sort of optimised my C11 HA setup. It is really weather cooperating and being there at the right moment. You are making good progress with your CAA HA setup. Expecting to see great HA images soon.

Alfred

I would like to share more information about the settings for the video recording:

I set the aperture to 5msec and push down the gain as much as possible to prevent saturation of bright spot. This is how a single frame looked like:

Image
It may look dark at time of recording but it gave me the details I want to capture. The other settings:

Gain : 22018 Gamma : 3.34 on the Basler acA1920-155um USB 3.0 camera
Best frame had a 56.4 quality number in AS!3.
I chose to stacked 1000 frames out of 3000 frames recorded. At the 1000th frame, the Q number dropped to 48.3 (or 48.5%)

I have discovered that I don't have to stack the best 75%. In this case I stacked the frames from the best 50% and the resultant image was ok. I must add that I made 4 recordings that morning and this was the best. The others were poor. Shows again that seeing plays a big part.

Cheers.

Alfred
