Hi,

yesterday night I made some test shootings at the night sky and discovered a phenomenon which I can’t explain and hardly name correctly. I would call it „multiple existence“:

Jupiter, X-T4, Samyang 135mm, 1s, f2, ISO2500

it only appears on the bright Jupiter, not on fainter stars.

what I tested is, that it’s not dependent on

  • Camera (happened on X-T4 and X-T2 as well)
  • lens (happened on adapted Nikkor AF-S 80-200 f2.8 as well)
  • ISO
  • f-stop
  • shutter type
  • exposure time

Cameras where in fully manual, no IS/NR, uncompressed RAW, triggered with 2s selftimer.

As far as I know X-Tx cams are quite suited for astro photography - so I‘m wondering what causes my issue.

Any ideas?

thanks,

Greg

As others have pointed out, there's nothing wrong with your shot (other than the fact that it's a bit overexposed).  You're looking at Jupiter plus some of its moons.  Try shorter exposures next time and you might start to see a bit of detail and color within the disc of the planet.

So... no issue whatsoever.
