issue fixed, we try again the acquisition

the sky is mostly clear

sky mostly clear. 07:50 error during the acquisition (SETUP command failed) The problem is the same at the beginning of the night. At this time TO can not call the support, he goes to the telescope and he tries to solve the issue.

no good, facing the wind that is too strong, change target

5:30 wrong acquisition, do it again
