Jupiter Query

Same here, the sky is back to its old self.
The "artifact" in the Jupiter has to be either one of 2 things (presumings its not real),

1, Image capture artifact, dirt on a lens or ccd chip
2, Image processing artifact.

I cant tell exactly which it is, but it has to be one of them. Anyway, like you say, there is always next time.

In my opinion John, when I look at the 'clean' frame, the details on Jupiters surface are so small in your image, that a few of them appear to allign in this 'shape' you think your seeing! I reckon its just an optical illusion. If you had a much larger picture to start with initially, I bet you would not have noticed this artefact!

I checked your images with a colleague that took images on 16 June at 23.00 to 23.44 UT. There appears to be no gaps showing up, assuming you took your images at those times. However, the SEB is very busy at this region and there are two EB/NEB festoon rifts at those times. It is also possible that the close proximity of the Red Spot and the bright festoons, apparently show left shape configurations. I still think this is a weak explanation because your resolution is low.

It's possible the image processing may be pushing or enhancing those brighter parts, due to low resolution, giving one the impression/illusion of a gap within the band.

Thanks Eamonn,

It's frustrating at the moment with the limited equipment I have (resolution and clarity). I agree with your explanation that the brighter parts have been pushed by the stacking to create an illusion. Still, it's useful to have the help of others on this forum, just in case there was something going on.

I've no doubt John that you'll have a bigger scope in the not too distant future which'll give you the resolution you want.

I always find threads like this by far the most interesting on the boards, its great to think outside the box and be challenged by a good question.
Thanks for putting this up John.
