NOTE: Regarding yesterday’s issue with the slight elongation on the images, the TOs run tests in the morning and the telescope is in excellent condition. They came to the conclusion that the issue was probably temperature related. For this night, we will continue checking the acquisition images and if we see distortions, we will re-focus.
