What's that then... (celestial object in photo)?

[Pupp]

Messing around with long exposures in Cambridge last night as there is a building illumination festival on.... on this and others taken around the same time of Kings chapel (from Clare), there is something apparent to the left of and level with what I assume must be Jupiter. Pretty sure it's not a sensor or lens smudge as it's only on those and looks a bit comet like to me... any ideas?

Too long for that and too long between the various shots with it appearing in the same place I suspect but can see what you mean...

And 20 deg to the left of Jupiter...? You may need to click on the image to see what I'm describing

You can still get artefacts in the lens from reflections. How long was the exposure?

That one was 8 seconds... interesting (to me) thing is the images either side of it with different exposure times also show exactly the same feature in the same location. The captures were some time apart as I was messing with settings and also using the shutter release timer so probably a good minute apart.

Thanks for the replies anyhoo

There's a crop of it straight from the camera RAW file so no processing apart from conversion to JPEG...
