    ISS flyover about an hour ago:

    DSC04091-1_zpsopt51s0v.jpg

    800/5.6, 1/1000 s, ISO 1000. ISS was maximum magnitude -2.0, I tried to 'pre-calibrate' against Vega but still underexposed.

    I looked for it. But the moon was on blast, and it's bright around here to begin with.

    It would have appeared moving right?

    Even as blurry as it is, that's awesome!

    Here's what I got from tonight's flyover- it passed close enough to Arcturus for this:

    and the video:


    deets: same lens settings, except 1/1250s. ISS max apparent magnitude -3.1, max elevation 78 degrees.

    Right- just like an airplane, but no flashing lights.

    Cool. So a stationary camera with a telephoto?

    no, not stationary
    with any sort of telephoto lens big enough to give the sort of image size that Andy got he used 800mm, you are going to have to follow the object across the sky
    it will move out of field of view very quickly

    Yes, I kind of assumed maybe he'd gotten it aimed before the pass...
    I have seen the ISS a couple of times, and yes, it moves right along.

    Tonight's flyover- this time the station is front-illuminated:



    1/1250s, ISO 800. apparent magnitude -3.3, elevation = 58 degrees.

    Yes, it's a telephoto lens on a stationary tripod- I slew the lens a few degrees/s to keep up, tho. A minor point- for the second movie, I had to alter the tripod a little to enable near-vertical orientation, like this:

    and as a consequence, the camera executes a 180-degree roll throughout the sequence of frames which I did not remove.
