• 800 counts. Strange behavior, looks like shutter got stuck. Test with V and r fast OBs.
• Shutter seems not to be working. Try shutdown and restarting the camera.

02:00 - No way. Shutter in strange position

• Try to move with testpower and minicom.
• Succeeded.

02:20 - Exposure ok. Restart (35 min downtime, although it does not affect science time, as it happened during twilight)

02:23 - Slew to NGC 2264

02:25 - dofpia,/BlueOnly

• Usual Z7 -3000 Needed

02:28 - dofpia,/BlueOnly

02:32 - dofpia,/BlueOnly

• still not converging properly, sends crazy Z4=-13544
• Z4 +14000
• Z7 -2000

02:38 - try again....
