ISS Predictions – Selected Areas

I have set up a program to automatically compute the ISS transits for different places and upload the results once a day – at around 11:00 am each day. See Zoom-Zoom for the impetus for this as well as references.

NOTE: If the maps come up “empty” it usually means there are no passes in the next 11 days that meet the criteria (within the stated radius and at least 20 degrees or higher in the sky). Also, if the predictions are really old, it means something is BROKEN.  You can leave a comment to let me know as I don’t monitor this very actively.

Please note that intermittently, the application fails to run and update the charts.  Sorry ’bout that.

    I’ve picked up quite a few tips along the way. In no particular order here they are:

    1. Double check! Orbits change and what may have been correct yesterday may be different today
    2. If using e.g. Stellarium to plot the path, make sure it is using the latest “orbital elements”. One day stale may mean a few miles difference.

    Well, it seems you CAN shoot the ISS through some clouds.

    Note that this shot used a Baader Astrosolar PHOTOGRAPHIC filter which is more naturally white but NOT suitable for visual observing. The texture of the clouds is pretty obvious – but the sunspots are also nonetheless visible. Because the clouds were rolling by, I elected to shoot the images in AV mode to handle the abrupt changes in brightness. The shot with the ISS was taken at 1/2000s of a second at ISO 100. The equipment consisted of: a 600mm Orion ED80 refractor telescope, a Canon 1.4x Tele-extender, a Canon 50D all on an Orion Astroview equatorial mount (though the mount was only used as a glorified tripod).

    The effective focal length of the shot is therefore 1344mm and the effective f/stop is 16.8.

    Very cool! I wish I hadn’t gotten caught up in all these “seeing” talk and went out and tried it. I’m the last one without a solar transit. Nicely done – their solar panels were looking right back at you!


What do you think about this?
