Its been a while since I have photographed the moon so I figured it was time. Once again the 800L doesn't fail to deliver. Even with a 1.4x TC on, the image was sharp and the CA very well controlled. It was quite a windy night and I could see a lot of scintillation and rippling on the lunar surface. Still this image probably has more true surface detail than many of my previous attempts.
