Just to provide some sense of image scale, here are examples of a close-up of a region of the Moon, overlaid with images of Mars and Saturn, all taken with the same set up - Tak Mewlon 180 F12 and Tak x1.6 Extender at an effective focal length of 3456mm.
I have shown the close-up lunar region on a full moon disc so you can better understand the size differences between these bodies.
Cheers
Dennis
