First image of Jupiter for this season

I had a late start with Jupiter this season. Conditions weren't good this early morning. Both seeing and transparency were poor. I was able to produce a fair RGB image. Some artifacts are evident in the northern hemisphere of the green channel image due to some fine dust in my DMK camera.

The NEB is quite and narrow this time round. The SEB looks rather active. The planetocentric map shows the position of the GRS. From the above image, bright patches next to the GRS as well as on top of it are present. Are these a series of strong vortices? Better seeing conditions would be able to verify this. The strong wake associated with the GRS maybe giving rise to these features.

Moreover, the GRS is shown as a light orange colour, with a hint of detail at its centre. Its signal is very evident in both Green and Blue channel filters. After further processing, the GRS in the blue channel in fact shows some more internal detail as shown below:

  1. Not that bad, somehow I'd prefer the blue, though the combined effort is very valid. Wait some more weeks when the planet rises earlier and the atmosphere steadies and get better results.

    Archimedes lunar shot superb, ore so the rills on the left. I never tier when looking at the moon when this area shows. If you can try when the shadows are on the opposite, i.e. about the last quarter, but you have to get up well before sunset. Then compare the views and the results are very interesting as it shows a different observational aspect.

    Unfortunately, NASA gave up the moon eons ago for the planets. They should explore these TLP's by landing spacecraft there as the moon interior is very illusive and worth exploring. By now we should have had regular lunar manned explorations. The Shuttle was too expensive and time waster and too complicated. Now NASA depends on the Soyuz for manned space launches.

    Their so called Orion Command Module is just an updated version of the Apollo, but still unable to be used before four years time, at least, maybe will be mothballed before we know it. USA has to rely on the private enterprise as seems to produce rockets/spacecraft much cheaper and faster..

    Luckily for us here on earth we are blessed by enjoying the Moon through modest equipment without incurring astronomical expenses. And this is free for all.

    So keep up the good work.
