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.
