Hi MaG !
Yes it's been years. Glad to be back. Thanks for your quick reply.
I have followed Judith's solution very carefully many times. No go.
I suspect that something is not right with the game I have loaded.
Someone mentioned that some copies of this game were glitched.(?)
The telescopes do not seem to be functioning properly.
After inserting the 1st filter, it pops out when I insert the 2nd one.
Also when I click on the telescope, a black square appears behind it.
I have to click again to get magnifaction, and the filters are both out.
That square looks a lot like one that appeared in another game I was playing called Aura.
It was a game malfunction, corrected by reinstalling the game and starting over.
When I traverse the ramp without touching the telescopes, each gate has a red 'rust' stain on the gate deck on the left (not on the 'path'), except the last one. When I work the scopes as best I can, that stain is moved to the right onto the 'path'.
It's not actually a hard puzzle, the hard part is how to operate the scopes. I've got the order down, but the filters have me knashing my teeth and rending my garment !
Any thoughts? Do I need a 'save'?
I'm too old to know everything...
