Telephoto Photos

I shot this moon photo in my front yard in South Florida using an old Nikkor 600mm f/5.6 on a tripod and tethered to my android tablet. I also had a kenko 1.4x teleplus converter on the lens and shot it on a Canon 7d mark ii. This was an out of camera jpeg and this lens had amazing sharpness and lack of purple fringing around any craters.
