Video shows completed adjustment of primary mirror tilt, using Barlowed Laser method.
Notice how the cross-hair of Cheshire collimator perfectly aligns with center donut of the primary mirror, and reflection of donut (small black dot in the donut).
Due to shallow depth of field, I was not able to focus on both cross-hair and center donut of primary mirror at the same time.
iPhone XR and Nightcap was used to capture this video.
Apologies for the background noise.
