will give a sun plot for any day and time.
On any given day, you can probably locate the satellite azimuth.
You might also be able to get a vertical reference in comparison to some
fixed objects.
Then, you have to translate that into the offset angle into the dish,
another field with plenty of bad advice posted on the internet.
I saw the azimuth angle of the sun as a non-shadow along the mounting arm
of the LNB. The vertical component was left to signal-based adjustment,
but may also have equaled the LNB mounting arm.
rec.video.satellite.dbs might be a better group for advice.

The unknown offset angle is indeed a difficulty but it is possible to
visualize the focus (and at that time the signal from the satellite) using
some small mirrors stuck on the dish
