    Re: How does the AstraIIIb split mirror work?

    This question also has intrigued me, but I am no closer to an answer
    than you.
    Sometimes, at least in my inexpert hands, it can take a newly installed
    horizon mirror a while to settle down to a steady index and side error.
      You might want to check both fairly frequently to make sure they
    settle down.
