keepsake observatory puzzle

Hi Guys.
I am hoping that someone out there can help me, I am playing Keepsake, which I know is rather an old game and have got part of the way through, albeit using various W/Ts, but am absolutely stuck on the Observatory puzzle.
My problem with this puzzle is that I cannot figure out which wheels to turn to get the 4 co-ordinates, as none of the W/Ts tell you which ones to click on. Is there anyone who can tell me which wheels to click on and in which order? PLEASE!!!
Hoping in anticipation.

I haven't played this game, but just in case it would be of any help to you, I found a YouTube video for this puzzle here.

Of course, if this isn't the right puzzle, please let us know.

There are also UHS hints for the game (don't know if they would provide any further help/explanations), but you can find that here.

I have played the game, but it's been so many years, I don't remember this puzzle at all. I'd suggest that YouTube video Marian posted a link to.

I don't remember this puzzle, or much else about the game, but it appears that you click a ring to rotate that particular ring. It flips around to confuse you, but the net result is that it rotates the ring you clicked on. You are trying to get the required numbers of each set in the top 4 as pictured in the walkthrough

The waltkhrough tells you what the numbers are in the four sets.
