Hello, I am a beginner photographer and had a coulple of questions regarding photographing the moon. I have a Canon 1DMarkIV coupled with a 70-200mm f2.8L lens and two extenders - a 1.4x and a 2.0x. My first question is on the settings of the camera. What settings do I use and why? (just so I can understand it). Secondly how best can I use the extenders to photograph the moon. Can I stack them up like so - 70-200mm f2,8L lens attached to both the 1.4x and the 2.0x ...to get more range? Thirdly, are the settings on the camera different if I were to stack the extenders and what are the settings and why? I tried to take a picture last night of the moon and all I got was a bright spot ..thats it just a bright spot. I see other people getting so much clarity with their equipment using the same equipment or similar - like a T3i or a canon 40d with a 70-200mm zoom lens. I would truly appreciate any reponse so that I can learn how to shoot the moon. thanks!
