I use my Meade LS 6 ACF mainly for visual observations. I wonder if the Meade f/6.3 Focal Reducer/Field Flattener can be used with this ACF telescope and - if yes - how could my visual observations be improved. What will be the focal lenght for this 1524 mm scope after adding the Focal Reducer ? I know the visual field will be enlarged but will the brightness of the DSO be improved as I have heard ? Is there a vignetting efect which can be visually detected ? Thank you in advance for your reactions.
