Luck and a cloudless clear night allowed me to try a shot at the crescent moon. My Canon T6 Rebel with it 55mm lens did not give very satisfactory results, even with the telephoto converter lens. However a lens adapter and my old 35mm Pentax 210mm zoom, was a great improvement. I do not recall the digital to 35 mm lens factor but I believe it is a bit over 300mm equivalent. I also discovered that no matter how carefully I push the shutter there was some camera shake. But, a 2 second shutter delay took care of that. The lens was manually focused, set to f22, 1/100th second, ISO 100, 2 second shutter delay.
