I should have an Skywatcher eq6 mount soon and should be sufficient for what i get. think that the Maksutov-Newtonian will give better images but not sure how it is for visual? i have heard that the Maksutov-Newtonian is difficult to collminate compared with newtonians also that the dept h of focus is very shallow. does anyone have experience of
