#zodiacallight — Public Fediverse posts

This slide from the #coronagraphs symposium in Boulder from the talk by Sam van Kooten is quite enlightening: it shows two processing steps of a #PUNCH WFI composite, on the left still dominated by the F corona i.e. #ZodiacalLight i.e. interplanetary dust (just as seen in the Artemis II eclipse images) while on the right the - at such distance from the Sun muuuch fainter - K corona has been brought out which traces the Sun's magnetic field.

Part of the #ZodiacalLight and #earthshine - with Mare Crisium - in yet another #ArtemisII image: https://images.nasa.gov/details/art002e009298

The #ArtemisII picture I had been waiting for - the dark Moon with a bit of #earthshine on the left in front of the #zodiacalLight going all around: https://images.nasa.gov/details/art002e009301 (this is essentially the Apollo 11 image from 1969 - https://www.facebook.com/dan.fischer.393/posts/pfbid02mf6UK3L2j5SgPiQsJk9JVYmo6XvZwDDZ23BYpXwJPDszaSpUYzuinkMyHzh9RF8Rl - again but with the Sun more centered ... and with half a century of photo tech inbetween).

And here the crappy external camera with the low data rate actually delivered: the #ZodiacalLight pyramid at the beginning of the #SolarEclipse for #ArtemisII - it stayed visible in the live feed for 10+ minutes! Contrary to the NASA commentary this was not the first time such an observation had been made by humans in the vicinity of the Moon - the Apollo 11 crew made it on 19 July 1969: https://www.facebook.com/dan.fischer.393/posts/pfbid02mf6UK3L2j5SgPiQsJk9JVYmo6XvZwDDZ23BYpXwJPDszaSpUYzuinkMyHzh9RF8Rl -> https://skyweek.wordpress.com/2024/07/25/allgemeines-live-blog-ab-dem-25-juli-2024/#Jul26

#ZodiacalLight from #Oxfordshire, UK on 25th Feb '25. It's the faint triangle of light that extends up from #Venus to the Pleiades, caused by sunlight reflecting off #InterplanetaryDust. It's a challenge from here because of increasing light pollution. 39x25sec + 20 darks, Canon 1100D +10mm lens. #Jupiter, #Uranus, #M31 the #AndromedaGalaxy & #M33 the #TriangulumGalaxy are also visible in the image.

I had about an hour after sunset last night to try to capture the cone of #ZodiacalLight (sunlight illuminating #InterplanetaryDust) before the Moon rose & I got it! Canon 1100D +10mm lens, 19 x 25sec ISO-1600 f/4.5. Stacked using #Sequator Oxfordshire, UK
