Thanks John....sorry for the late response. For the moon, I was using the ASI Camera-straight into the back of the scope For both the ASI585 and the 224. Pinpoint focus was not possible on the 585. For the 224, yes. When i've used the 174, same image train and also focused. I tried various camera settings, but focus was not possible with the 585 and the 9.25" telescope.
