Star ghosting/flaring or light bouncing?

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

Moons?

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.

Thanks

Thanks @Jerry-astro,

good points with overexposure.

i was so confused about the „issue“ that I wanted to get it as clearly as possible, image quality was no concern anymore.

So I guess that my gear is quite capable in resolving the Jupiter moons

Clear skies

The flaring you see coming from Jupiter looks like diffraction. Jupiter is the closest, largest and brightest object in the photo. The other point sources of light are it’s moons, which Jupiter has a constellation of over 60 moons if I recall correctly.

Im no astrophotography buff, but I do love observing the night sky and learning about astronomy and astro physics
