Description

Jupiter is still at dusk when it passes through the meridian, so there is a loss of contrast detrimental to the quality of the videos, but also normal atmospheric instability at the entrance of summer.

So I hesitated to publish this first image given the poor quality especially of the

channels G and B.

Alone, the IR 610 filter did its job, and that's the only reason I decided.

Technically, I made 4 videos of 74s per IR + G + B channel (from 03: 21 UT to 03: 35 UT or 14 minutes of derotation) and retained 6000 images / 72,000 images).

Creation of an IR+G+B image on WinJupos then L+IR+G+B on Photoshop with L=IR (IR reworked in grayscale and sharpened).

The GTR is just visible on the limb of the planet.

Orientation of the planet for aesthetics.
