Hello everyone!

 

Look at these images. The first one is a composite of a regular pic with the same one overexposed. Note that the moon only appears when the photo is overexposed. In doing that, I noticed these red and blue dots around the planet. Could they also be tiny satellites? Any idea?

 

Thanks!

 

Ed

Maybe some sort of chromatic abberation?  The moon has a smaller red halo as well.

It's camera noise from the glare of the overexposed image of Jupiter.

These are known as the "Muskovite" family of Jovian satellites--they were put into orbit by Elon Musk just to further annoy astronomers.

I wouldn't fire off a discovery report to the Central Bureau for Astronomical Telegrams (CBAT) quite yet. Oh, would that discovering moons were this easy... but no, as the end of a freshly-cut rope might say... "I'm a frayed knot!"    Tom

That's camera noise, enhanced by whatever processing you're doing. Looks like you're using Registax 6 wavelet processing. The ringing is a well known side effect.

 

It would be physically impossible for a 6" scope to resolve any such "moonlets".
