  1. The Sun in H-Alpha light (656.23 nm), 22 august 2024. Prominences.

    A couple of images I did manage to save from a session during a quite bad morning for imaging the Sun, due the poor seeing and the sky transparency. I did like the results, though.
    Details and links to the better quality images in the alt text.

  2. Ein kurzer Blick zur #Sonne. Übung macht den Meister.😄 Visuell aber sehr beeindruckend.

    A quick view of the #Sun. Skill comes with practice. 😄 Visually impressive though.

  3. On Sunday it was 8 years to the day since I photographed the biggest solar #prominence I've ever seen. It was 100,000 km tall & that tiny dot is the approximate size of Earth to scale. Taken with a #CoronadoPST + Canon 1100D with 2x Barlow #Sun #SolarImaging #SuninHAlpha #Chromosphere #SolarFeatures

  4. When we observe the sun under Ha filtering, we are able to see the sun's #chromosphere and its #prominences. The chromosphere is a gaseous layer, mainly hydrogen, which lays above the #photosphere. The high temperatures at that layer causes the hydrogen to glow red at that wavelength, hence the Ha name. Also, you could be able to see a #prominence, which is an eruption-like event of solar material thrown out into space!
