Pls help identify the object in the picture ,is it just a flare ,reflex on the lens or Am I misssing something in Stellarium?This is 20 sec exposure,at ISO 640,taken by Canon 7D with a Tamron lens attached f 4,5 at the focal lenght of 141mm,I took another exposure of the Jupiter but It was exactly tyhe same?  Intrigued:)

What am I meant to be looking at ?

[Marek]

The fuzzy object on the right side of the Jupiter ,slightly upwards:)

[Rick]

The important information lacking is the date and time of the photo...

[MarkS]

It's not a sky object - it's some kind of lens internal reflection.

I can see 4 moons of Jupiter!

[MarkH]

Yes I think that's an internal lens reflection somewhere.

The date was 25.03.2014 time 09 59 PM,now i belive in flare version ,it was apparently caused by an UV filter ,next time I will remove it before taking a photo:)

I had something similar once and it turned out to be a reflection from a green LED on one of my gadgets nearby. After I fitted a dew shield it disappeared.
