It does not look too far out to me. If it stays clear give the scope a star test on Polaris - the images either side of sharp focus should look like a polo mint with the dark shadow of the secondary being the "hole" in the middle. If the shadow is central in the "polo mint" then the scope is in reasonably good collimation.

Looking good, a slight tilt but a star test should confirm.

It should be slightly offcenter if it is a fast scope.............small F number and central if slow high F number................if your scope is F4/5/6 then it looks ok

but like already said focus on Polaris and focus in and out to see if you get a doughnut, if the dougnut ring is in the center then you are OK.

Happy viewing tonight
