 5.5 Slewing to a Target Using Cosmic Debris\\ 5.5 Slewing to a Target Using Cosmic Debris\\

-It is typically dark enough to lock on your first star if TT reports ~ 1000 counts while not point at anything (sky counts) with the SpyCams turned off. This is roughly around 20 minutes after sunset or the time of twilight reported by Cosmic Debris. Here are instructions for slewing to a target and initializing the telescopes on a bright star at the start of the night: You may want to find a bright star near your first target to check the pointing of the telescopes and to do sky flats for the telescope DM's. The [FIND STAR] button on the MAIN tab of the obsgtk is useful in finding a suitable, bright star. It will report the star name, mag, and ALT and AZ in the text window at the bottom of the gui. There is also a printed list of bright stars in order of RA in the binder on the left side of the control room desk. If your first target is bright, then you may slew to it first. Enter the HD number of the star into Cosmic Debris using the Object or Calibrator Tabs. Click the [HD] button to register the entry. (Alternatively, you could enter a CHARA NUM, IRC, HR, HD, or SAO number and click the corresponding button.) If a star or new target is not recognized by Cosmic Debris, [[:chara:trouble_shooting#adding_or_finding_a_star_in_the_chara_database|follow the procedure below for DBADD]]. Check to make sure that EL/AZ reported by Cosmic Debris are correct and safe for pointing (never point below 15-20 degrees elevation). It is recommended to initialize the telescopes on a target between 40-70 degrees elevation. Hit the WHEN button for your first star to see a plot of cart positions and when it is in delay. Enter the ideal reference cart position into the REF text window on the Cosmic Debris Control Tab. Click the [REF] button to send the reference cart position to OPLE. Slew to your first star by clicking [OBJECT], [CHECK STAR], [CALIBRATOR 1], or [CALIBRATOR 2] on Cosmic Debris (depending on which field you entered the target information). Note that these buttons will slew the telescopes AND send the carts to their positions. Verify that the telescopes are moving by checking the azimuth and elevation status in the telescope servers (the left set of numbers show the commanded EL/AZ of the target while the right set of numbers show the current location of the telescope). Also view "SPY1" to check that the telescopes and domes are moving. If the domes do not rotate, click the AUTODOME ON button to enable the domes. The telescopes will usually arrive at the elevation of the target first and then continue in azimuth until the star appears in the finder or ACQ window. If the scopes do not move, check that they are enabled. The telescope server will show RA and DEC coordinates if enabled and will show DISABLED if disabled. The update in the OPLE server will take about 20 seconds for all the carts to get the new metrology calculation. Make sure all carts are tracking to values between 0 and 44m. You might have to click [TRACK] for the reference cart on the OPLE Control Tab. The [OL] buttons should be depressed gray for ALL active scopes (including the reference cart). The [MAN] buttons should be depressed gray for the moving carts to allow the beam combiners to send manual offsets to the carts. (The [MAN] button for the reference cart should be green.) When the telescope slew finishes, check the SPY 1 to make sure that the domes are aligned with the telescope. In the ACQ window, hit [MOVE] under the TV tracking menu on the Main Tab of the Telescope GUI and then click the right star to bring the star to the cross-hairs. If the star is not in the ACQ window, go to the FIND window and do the same, then return to the ACQ window and repeat. If beacon alignments and sky flats are needed, do not center the star until the alignments are done first.+It is typically dark enough to lock on your first star roughly 25 minutes after sunset or the time of twilight reported by Cosmic Debris.

-Unlock the tiptilt beams using the Tiptilt servo control GUI. Turn the telescope TVs to SPY1 so that you can watch the telescopes and domes stow. On the Control Tab of the telescope GUI, click [STOW]. This will send the telescope and dome to the stow position.

After the M1, M3 and finder mirror covers finish closing, close the dome slits by clicking [SLIT CLOSE] on the telescope control tab for each telescope dome that is open. Close the dome enclosures by clicking [CLOSE] on the cylinder GUI. Watch that each reads .000 or .001 when closed.
