Don't get a maxfield 3.3 reducer. It is great for imaging but you can see
the central secondary obstruction when used visually. Remember to calculate
the exit pupil of your telescope/eyepiece combination. In your case
telescope diameter/magnification. anything larger than 7mm ( if you have
young eyes)
will just spill light on your iris and not into the pupil of your eye. Have
someone measure your dark adapted pupil and use it to calculate the proper
focal length eyepiece for your telescope.
