Collimating query.

Hi everyone,

I am trying to work out if my OTA needs collimating.
I have a loan of a collimator and when I insert it and look down the OTA (I leave the cover on the OTA) I see 2 circles. These circles aren’t completely overlapping, they are offset a bit so I assume it needs collimating.
Around the aperture end, there are 4 sets of 2 small screws.(See attached pic)

Are these the screws for adjusting the collimation? If so, Do I just adjust them till the circles overlap?

Thanks for any help
John
