Moon with 400 f/5.6 + 2x + 1.5x

[Mark Itol]

Sharing a shot of the moon using the 400 f/5.6 with a 2x and 1.5x (yes, 1.5x Kenko) TC attached. I've never been able to capture this amount of detail with the bare 400 f/5.6; I guess the magnification by the TCs is enough to cancel out the loss of IQ.

Thanks for looking.

Mark, The IQ is good. Perhaps the use of f17 did the trick. I really like the shadows from the craters on right side. :S3:

Looks pretty good Mark! I might go a bit btighter but a very nice job stacking the TC's!

Thanks, Steve and Roman.

Steve, f/17 is actually wide-open (f/5.6). :S3:
