Jupiter images

by Vern on Jul.23, 2009, under Astronomy, Planetary

I set up this scope this evening with plans to image the GRS shortly after 1 am then to image the new impact site when it transitted at 3:25 am. I screwed up and lost the first few images of the GRS transit by forgetting to rename them.

Here is the first image at 1:30 am. Jupiter-2009-07-23-0215mdtNote the prominent spot to the northeast of the GRS. Seeing was not good, maybe 4/10 so it was difficult to judge the size as bouncing around a lot. Even so, it was clearly visible on the monitor and through the eyepiece. For a while I thought this might be a new impact — nope it was just Callisto’s shadow — even though Callisto is quite a distance to the east.

Here is one from 3:08 am, note the impact from a few days ago can be seen near south pole.

Next one from 3:15 am mdt, turbulence improved to maybe 5/10.

And finally 3:53 am, shadow very near the limb:

    I’m looking for somebody who knows some astronomical computer programs. I recovered the stars from 30 NASA images and I would like to prove that they were taken on the Moon.

    Anybody knows such computer program?
    Anybody could do it?
