Doubtless someone has already done this,but i havent seen any results.

Thanks Chris. I remember someone posting a great tracked image of an ISS pass about a year ago, but I can't remember exactly how it was done. Most likely just a standard tracked widefield shot I imagine. I'm yet to get myself a mount that will handle the weight of a dSLR.
And thanks again for the invitation to your dark skies.

I watched it come basically overhead (with Laptop and StarryNight intow)
Took a grainy photo and a video seconds before it went into darkness.

From where I am 38 degrees south, the ISS stays in light for 93 minutes:30 sec (+/-30 secs). Unsure if latitude comes into play??

But finally for many years, I've wondered at what precise moment, does the ISS go into darkness. Now I know...... I WON!
This comes in handy for Shuttle missions too.
(but will only apply when shuttle is at the ISS's altitude. Lower altitude means shorter time from sunset)

So if a pass is over you, make sure it falls under 93 minutes from sunset.

93 minutes, that's interesting. I've never thought to measure it. I'm guessing it would change a littlre bit with latitude? Can't quite figure out how though.

Brett, Did you notice how the station reddens as it passes through the shadow of the atmosphere? I got a nice image of this last year.

Cheers,
Stephen
