Strange green mist

Sombody know what the strange green mist is? Grtz

That’s weird, never seen anything quite like that before!
If you look at the single-image cutouts,
you’ll see that it only appears in one of the r-band (=green here) images, so it’s some kind of transient or artifact – possibly some kind of glint in the telescope?


Thnx for your response so quick. Yes I looked at the other images. Thought (still think) it is kind of strange. The edges of the “green fog/mist” looked scattered so I didn’t thought it was something with the lens at first sight. Still a little foggie :wink:
