Single-Star SNAFU at Prime

See section gif for full details:

  1. If not yet done startup ADAM.
  2. Move the rotator to position angle 180 with the ADAM command ROTPOS 180.
  3. Slew the telescope to the SNAFU star, as for Cassegrain mode.
  4. Take a test GLANCE exposure of the field (1-5 seconds; use filters if the star is very bright). The CCD image will appear on the LEXIDATA and the star should be visible near the centre of the chip.
  5. Use the Grinnell MOVESTAR command, and locate the star with the cursor. The telescope will move and the star will move on the Finder TV image.
  6. Mark the position of the star now on the Finder TV screen with a felt pen or similar marker.
  7. Move the telescope again to the original position by pushing the SCRE button.
  8. Type at the User Interface:

    SNAFU

    and move the telescope with the handset such that the star image on the finder coincides with the position marker put in step 6.

  9. Press the ACK.
