There is a prog. out there that can show the configuration and
orientation of the ISS from your location but I can't for the life of me find it.
It'd be interesting to check it out all the same.

I just saw the ISS pass very low on the southern horison, 6 degrees max elevation.
I had to go upstairs to the bedroom window to see it, cool all the same.
Looking at sat tracker, it was off the coast of Portugal at the time, amazing!
I cant think of the program either Frank.

Anybody who says that Earthshine is reflected Sunshine is talking Moonshine.

If you have an equatorial mount you should be able to adjust it to track the ISS.
Instead of using Polaris as "pole" use the point in the sky around which the ISS is orbiting on any one orbit.
In the 2 minutes you need for a given pass the rotation of the earth will "trail" that "pole" by just half a degree,which isn't bad.
The ISS orbits every ninety minutes. In ninety minutes the earth will have rotated 22.5 degrees.
For the next overpass of the ISS, 90 minutes later, you will have to swivel your tripod legs in a clockwise direction by 22.5 to keep alignment.
A handy orbit to start off with would be one in which the ISS is orbiting a point directly north of you.
Such an orbit brings the ISS almost directly overhead of Cork City.
