Although I joined in 2014, I've been too busy running a business to get too involved and now with the COVID-19 crisis, have finally dusted off my 14" Celestron Edge HD six weeks ago only then to have a catastrophe when a Northern Gale blew the dome off the top of my Pulsar Observatory! 

During that night rain got into the RA drive and completely ruined the electronics and after struggling to find support from the original supply chain, decided to upgrade the mount to a CGX-L which in itself created problems in that the mount is 200mm lower than it's predecessor.

Not only that, the bolt positions for the new mount needed re-drilling to get a better Polar Alignment.

Unfortunately, during this major re-build and because of the significant weight of the components, on one occasion  struggled with the tube, which had a considerable bump onto a rubber floor.

I now have a problem as during the process of aligning the finder scope with the main Tube, I find that although both focusing well at short distances, I cannot get the main Scope to focus on a star.

Could this be a collimation problem or even worse a main mirror mis-alignment?
