== P3.6	Orient the coronagraphs == 
•	**Phase**		:	3  
•	**Status**		: 	Draft	 
•	**Category**		: 	Nighttime testing (functionality and operability) (C4)
•	**Recurrence**	: 	once at commissioning
•	**Duration**		: 	40 minutes
**Description**
•	Adjust the orientation of the coronagraphic masks with respect to the true orientation of M2 spider.
**Prerequisites**
•	Atmospheric conditions: should be able to see bight stars on the sky (preferably close to zenith?).
•	Authorize SHARK-NIR on the SX side.
•	Suitable bright enough star close to zenith to have negligible effects from flexures (including the possibility of performing AO).
**Procedure**
•	Pointing to a star, the first coronagraph is inserted in the path. The bearing is rotated maximizing the contrast achieved on the SCICAM.  (use the pupil lens to see the pupils alignment maybe)?
•	This operation is repeated for all the coronagraphs. 
**Success criteria**
•	All the coronograph are aligned to the true orientation of the M2 spider by maximizing the contrast at SCICAM. 
•	Note down the contrast achieved for all the coronograph including the atmospheric conditions and the brightness of the on-axis star.
**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?
