Sonnenflecke / Sun Spots - 20220425

Little children paint yellow suns and blue clouds on a white paper – we all did it once upon a time.

As grown-ups we have learnt the sunlight's color is what we define as white or neutral daylight. Sunrise or sunsets only appear yellowish, orange or even strongly red because the light rays are diffused, distracted, dampened and filtered by the quality of the local atmosphere. The more dust or soot up there the more of only the longest wavelengths pass through – that is red.

Maybe because the yellow-black contrast is the strongest for our eyes' perception, maybe for sentimental reasons I (and many others) still use yellow colors to present the sun disk, even here on AstroBin. This color may origin from any sort of non-neutral filter material or by just coloring the sun in post processing as I did so often.

However ... this time I decided to present my stacking result as a color image which shows the natural color temperature of our most important star: white.

NB: April weather at it's best, with instant weather changes, rain, gusty winds, rushing rain clouds, rain showers, some high clouds above all ... and very rare little blue spots where the sun is permitted successful imaging session of the beautiful sun spots these days.

I only had 10 seconds for the 50 single frames I took. The last couple of frames show passing clouds already and afterwards, in an instant, the next rain showers came in ...

Given these environmental circumstances, I'm happy with the detail I carefully worked out of the stacked image.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
