Real nice image.  Was it hard to align?  Did you use the ZWO for imaging?

Thanks ,Pentax k50 was used for the image , I found a site for a easy way to tune these up,my primary was out a tad and I had a lot of tilt between the focuser and the primary  ,easy fix with a laser ,also the primary was vary loose

www.hnsky.org/RC-collimation.htm       Note  ,when I removed the secondary I did not remove the 3 adjustment screws ,just backed them off a tad so the center screw would break free .This will keep the distance about  the same when you reinstall it .Also when rotating the focuser to align it with the primary I had the drawl tube to where my camera was in focus and had the tension adjustment screw fairly snug  ....

 

Remember ,once you rotate the focuser and have it lined up it needs to stay there ,you will need to rotate the camera instead

Thanks very much for the link and the tips!   Note The link should have an underscore instead of a dash after rc

I had to do some work on the focuser in mine.  The focus tube was canted in the focuser so if you rotated the focuser, the laser would form a circle on the wall in front of the scope.  Only after I added some more shims and screws on the focuser, I was then able to align the laser in the centre of the secondary.  After that the hnsky procedure works quite well.
