To be honest if you are finding focus I would recommend a bahtnov mask

I manually focus my Scopes, sad I know but I want to get it right. Even for me it's an easy solution and I use the celestron focus motor control using APT and the celestron focus software. With the magnifier over a bright star it is very simple. Note I do set the focus steps to 1.
