Hello TareqPhoto with the mak180 you can have long focal length (2700 mm) which will give you a lot of image scale with a girl barlow. In contrast to the 200 (F5) you need more barlow to achieve the same image scale as with the mak180. The difference will be in favor of the 200 (F5) because it has a greater flow of light than the mak180 (20 mm more than the mirror surface), only that, but both telescopes will have the same contrast / sharpness of the image because they have the same obstruction of the 20% which is what determines the contrast and sharpness in a telescope.
