== P3.3	Telescope control – telescope mode and offset == 
•	**Phase**		:	3  
•	**Status**		: 	Draft	 
•	**Category**		: 	Nighttime testing (functionality and operability) (C4)
•	**Recurrence**	: 	once at commissioning
•	**Duration**		: 	30 minutes
**Description**
•	For the correct telescope mode for SHARK-NIR find the offset direction and magnitude.
**Prerequisites**
•	Atmospheric conditions: should be able to see bight stars on the sky (preferably close to zenith?).
•	Authorize SHARK-NIR on the SX side.
•	Target maybe a pair of stars (not too bright) separated by ca. 1arcmin (known value)
**Procedure**
•	Send preset to the telescope.
•	Center one of the stars to the central pixel of SCICAM.
•	Issue the right offset to get the other star at the same pixel in SCICAM.
•	Return to the original star and verify the centering. 
**Success criteria**
•	The offsets produce telescope motions of the size and (particularly) direction expected.
**Notes**
•	Steve Allenson can create a paddle for SHARK-NIR offset if this info is given to him.
**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),
