I have a 150mm dob (yay!) and what's the most useful max magifcation? Like without distortions or burryness. Focal length is 1200mm if that helps in any way

For reflectors, like yours, I believe it is 50x/inch. So since your scope is 6", the highest useful power would be 300x. You'll only be able to go that high if the weather conditions allow for it. <div class="Discussion_UserSignature"> </div>
