| yep, he sure does have us beat ... but I'm loving the fact that I finally learned how to take a decently detailed moonshot! Never been able to accomplish that before ... I feel like a kid at Christmas! |

Yea, didn't mean to take away from fun from us, I am just learning as well. I finally got a shot that I am happy with!

Thanks for the info in this thread. Here's my attempt from tonite:
Sunny f16 +1/2 stop, contrast adjust in raw conversion
PS adjustments: High pass filter and very very slight curve adjustment |

Wow, everybody seems to be taking some decent moon pictures and here are my thoughts...
- Try to take the picture at a relatively clear night, and when the moon is above 45 degrees above the horizon as this will reduce the atmospheric effects. If possible, go to the mountains. It will get better and better as you go higher.
- Use a tripod and if your camera is capable, use the mirror lock-up.Use the timer or a remote shutter release.
- I think f/8 (or somewhere between f/5.6-f/11 range depeding on your lens) is based on the sharpest image that you can capture with a lens. The new genaration lenses should yield the sharpest image around f/8 and older ones around f/11. If you are lucky enough to have one of those nice f/2.8 telephoto lenses, you may also try to go with f/5.6 I guess. I used manual exposure on the camera and set the aperture to f/8. This is supposed to be providing me the sharpest possible image that I could take with my lens as the depth of field is not a concern for this photo (see Bryan Peterson's Understanding Exposure Book).
- Use a spot light reading directly from the moon and set your shutter speed 1.5 to 2 stops faster than what the exposure meter tells you.
- Set your focus to manual and set it to infinity (make sure that it looks sharp on the visor though ;-)).
I just took two photos last night with these settings and it seemed to work fine for me.
This is with Canon 200 mm @ f/8, iso 200 and shutter speed 1/400. I increased the contrast and sharpness a little bit in photoshop. This is the actual size of the original photo. I just cropped it.
And this one is taken with a Kowa TSN663 telescope (supposedly equivalent to 800 mm) with a t-mount adapter for Canon 30D. It has a fixed aperture of f/13. Photo taken at iso 400 shutter speed 1/500. Increased contrast and sharpness in photoshop buy using adjustment layers - curves, high pass layer and multiplicative overlay. This is sort of reduced from the original image. The original cropped image was about 1600x1600 resolution.
Cheers,
Koray

Shot this in my driveway last night a little after midnight:
(a 100% cropped section - viewing actual pixel size)
Aperture: f/11.0
ISO: 100
Shutter: 1/350
Manual exposure
I forgot to use mirror lock up too - drat!
I'm still waiting for a better time when the moon is low on the horizon and REALLY looks big. |

Doesn't work.
Infinity and back it up. Hyper focal kinda' thing.
Believe it or not, AF seems to be more accurate than I can get it manually. |

Auto focus used here. This is a 100% crop, no resizing done. |

Yep, it may not work right at infinity. That's why I said check it from the visor ;-). I got a lock problem a couple of times with autofocusing onto the moon. That's why I decided to go with manual... But if autofocus works that's fine too. |

Hmmm, this may not be a good idea. When the moon is on the horizon, it just looks big. Actually, it is not big at all. Is is just an illusion... And you'll get lots of atmospheric effects. However, you can get a very nice colour (without any detail though).

Thanks for the moon shot pointers everyone. I got a decent one last night with my 300mm lens. Looks like a bit of fringing; if I ever get bored maybe I'll try to fix it...
