The Moon with a telephoto lens and teleconverters
Here is a recent attempt at photographing the moon with
a telephoto lens, on a stationary tripod: http://clarkvision.com/galleries/gal...-c-5x-700.html Canon 1D Mark II 8-megapixel digital camera, a 500 mm f/4 L IS lens with 1.4 and 2x teleconverters. The total focal length is 1400 mm for a full scale of 1.2 arc-seconds per pixel. Be sure and click on the full camera resolution link to see all the detail.

Just curious, how do you get optimal focus (any special tricks, or multiple tries on manual)? Bart |

Bart Bart, The 1D Mark II autofocuses at f/8 and stacked teleconverters only report one magnification, so with a 2x teleconverter on the lens, f/8 is reported to the camera, then adding the 1.4x between the 2x and camera, the camera still sees f/8 and still autofocuses well. So I used autofocus on the moon at f/11.2. Roger |

http://clarkvision.com/galleries/gal...-c-5x-700.html Wait for a calmer atmosphere (winter is, from my experience, the worst - spring and fall are better) and/or stack more frames. Here is one of mine: http://www.photo.net/photodb/photo?photo_id=2745849 17 stacked JPEG's on a night of better than average "seeing". The image was subject to a Laplacian sharpen post-stack, and maybe a bit of USM after it was resized to 1280x1024 (it makes a wonderful desktop). For precision focus, do not depend on AF: get the Canon Angle Finder C or equivalent and manually focus. It works _much_ better, despite the poor quality of the "C"'s image. However, this comment is based on Canon 10D experience; maybe the 1DMkII's AF is more trustworthy. (And your image appears to have suffered more from turbulence than focus.) |

Hi Roger,
I've been waiting for the Nikon D2x (as replacement for my D100), and the fact that I've had a bunch of fine Nikon glass for years. However, with the recent price announcement of $5,000 for the D2x, along with the uncertainty about it's CMOS sensor performance, I'm considering changing to a Canon system. I am NOT a fan of wide angle work so I'm NOT considering the Canon 1Ds Mark II. However, I AM considering the Canon 1D Mark II. I lean towards telephoto work so the 1.3 factor of the 1D Mark II is a plus for me. And at $3,750 street price, it's $1,250 less than the D2x. Now, admittedly it will be limited to 8.2mp versus the 12.4mp of the D2x, but I wanted to ask your candid opinion of your 1D Mark II. Any feedback on the 1D Mark II you can provide would be MOST helpful. Many thanks in advance... "Roger N. Clark (change username to rnclark)" wrote in message ...

Hi You might want to start a new thread so others might see it who are not reading a post about the moon. Having said that, your lenses (at least mine are and other serious amateurs and pros) are probably more expensive than your camera, and the lenses will generally last many cameras. For example, I started with a Canon EOS 650, then elan I, elan II, elan 7, film cameras, then digitals: Canon D60, 10D, and 1D Mark II. I still use some of my original lenses. My newer L lenses will probably last for many more cameras, and in general my lenses have cost me more than all my cameras put together. Why did I choose Canon for my first auto focus camera? Random at the time. I might have just as easily chosen Nikon. I had no preference for either at that time. So, do you really have "a bunch of fine Nikon glass" that you want to abandon, especially before seeing reviews on the D2x? Nikon makes great equipment. Great lenses, great cameras. Perhaps Canon is leading the digital arena now, but Nikon is not far behind, and the front runner could change in a couple of years. Do you have a big telephoto, like a 500mm f/4? Since you say you want to do telephoto work, I suggest if you don't have a super telephoto, to get that first, then assuming you have to wait and save money for a new camera, the whole camera selection and market leader could be quite different, and in general much better. If money is no object, and you can afford to change cameras and super telephotos and all other lenses, then go for it. The Canon lenses and cameras are superb too. But don't forget the Nikon D2x has some innovations the top Canon's do not have. Having said all that, the Canon 1D Mark II is a wonderful camera. The speed is awesome, the auto focus accuracy and speed is excellent, the signal to noise is excellent, battery life is excellent, etc., etc. I've been able to get action shots I could not get with my previous cameras. But I do wish for more megapixels. The speed of the 1D Mark II and the pixels of the 1Ds Mark II (16.7 MPixels) would be ideal. Maybe next year.... Roger "Roger N.
