Hi Roy
Welcome to Iceinspace it is great to have you as a new member...besides the astronomy stuff we have a general chat where you can discuss a lot of stuff...its like going to the pub but there is no beer☺
May I suggest you get a focuser mask ... if you want while waiting for one in the post you can make a simple but very effective focuser mask using a disk the size of your app (you can drill holes in your lens cap which I have done☺ but a disk two 1 inch holes opposite each othe an inch from the outter edge...when you look at a bright star it will only appear as one star when in focus ...so focuse until the two disk you will see if not focused become one.
Probably helpful with such a mask to take in focus photos but get a set for comparison taken after the disk has been rotated 15 degrees past its last photo position...that may show focus is fine in one position but not good in another position.
And focus takes a huge effort to get right and in my view takes a great deal of practise...thinking more you could do those photos at various scope angles and detect flex or as a like to think find that sweet region the scope really works well.
Good luck and hope you enjoy your time here.
Alex
