== P3.1 Telescope control – sending preset == • **Phase** : 3 • **Status** : Draft • **Category** : Nighttime testing (functionality and operability) (C4) • **Recurrence** : once at commissioning • **Duration** : 10 minutes **Description** • Preset of a bright enough on-axis star is sent to the telescope for verifying the communication to TCS, nighttime collimation model for SHARK-NIR, and the pointing accuracy. **Prerequisites** • Atmospheric conditions: should be able to see bight stars on the sky (preferably close to zenith?). • Authorize SHARK-NIR on the SX side. **Procedure** • Send preset to the telescope from SHARK-NIR computer/system. • Check for the position of the star at the SCICAM. If needed, correct the offset to increase the pointing accuracy and record the new nighttime collimation model for the instrument. **Success criteria** • Successful in sending preset to the telescope and therefore the communication with LBT TCS. **Notes** **LBTO support** • Support from LBTI/LBTO? • Presence of John Hill usually helps while collimating for the first time. • Steve Allenson (as the TO) will be a great asset too. **Associated SHARK-NIR personnel** • JF, LM, MdP, MM (from AZ), DV? **Date performed and by whom**
