    Default RegiStax, Jupiter, NexImage, Celestron 4SE



    There are two more Jupiter photos



    Jupiter with Ganymede Moon and Ganymede Shadow Transit
    September 18, 2010 12:33 AM EST

    Video file was taken with Celestron NexStar 4se, 2x Barlow lens and NexImage camera (total time 4 minutes, 5frames per second, 1200 frames, output 640x480). AVI frames stacked in RegiStax v5. Finally, image was processed in PhotoShop.



    Jupiter with Ganymede Shadow Transit and the Great Red Spot
    September 18, 2010 2:22 AM EST

    Video file was taken with Celestron NexStar 4se, 2x Barlow lens and NexImage camera (total time 5 minutes, 5frames per second, 1500 frames, output 640x480). AVI frames stacked in RegiStax v5. Finally, image was processed in PhotoShop.

    If in previous photos I used 15fps for this photo I used 5fps which allow me do not use very aggressive RegiStax Wavelet, and minimized artifacts as minimum for big images.

    It is interesting that “TheSky first Light Edition” shows not only location of Jupiter Moons, but also location of the Great Red Spot. Today at night I already think to go sleep, but when I found it, I just wait time when I can make photo of Jupiter moon shadow and the Great Red spot in one photo. I think that such prediction is a useful tool for choosing time to make Jupiter photos.

    Clear skies,
    Valentin

    I really like Ganymede and its shadow!

    I know very little about planetary astrophotography. (Well, I know very little about astrophotography, period.) Did last night's moon make it more difficult to take the video?

    Thanks.

    I just waited the moment, when it happens. The only one problem yesterday was weather.

    On the film you not really see how it happens, quality of original frames is not OK (4 inch telescope). Magic happen only after RegiStax.

    Small notice: Usually in normal time you see both moons and shadows but because Sun from other angle you may be even don’t understand from photo that this shadow connected with moon. But now we are close to opposition and Jupiter, Earth and Sun near one line. So it may be more obvious that shadow connected with the Jupiter moon. It is one of the Jupiter opposition effect.

    Clear skies,
    Valentin

    Great images. I'm going to try your 5 fps suggestion tonight - if the clouds ever go away.
