Hi Ken

I had an OMC 140 and it was a beautiful scope.

There are colimation screws on the back plate.

To be honest i have found that Mak's hold up well and very rarely need to be adjusted.

Indeed this to me is one of their selling points.

i am sure that you are going to love the scope

I had an omc 140, dont touch the 3 collimation screws unless you have to, but if it needs it then google daytime collimation, i did my one once and it was not so bad, but do a decent star test before trying it

[JohnC]

Also make sure the star test is always central in the field.

Sounds obvious i know, but you will see distortion as soon as you stray from the central point.

As Nightfisher says only touch it if you have to.

The ones i have seen have always been fine and did not need adjustment.
