    Here is how I feel about my recent attempts to "shoot the moon" with the D2x/Bigma:
    51015966.
    They are just not sharp. I don't think that is lens/tripod, or even setup (using a sturdy tripod/IR relase/mirror lockup).
    I think it is settings.
    Can someone recommend a combo of settings to try (ISO, shutter. aperture).
    I'd like to try again tonight and I'll let you know how I do.
    Thanks.

    Pat,

    Here's my last attempt at a moon shot. These were shot with the D70 / 300 2.8 + 2.0 TC. The EXIF is also shown.

    Paul gave you some good information. (Man that hurt to say :wink: ) The Bigma is best stopped down between F8 and F11. If you do this your shutter speed will be to slow and will get motion blur from the moon or your tripod. Raise the film speed to get shutter speed out of the danger zone and now you add noise.

    Having fun yet? :smile:

    Moony f/8-11? I think you've coined a new photography term Bjorn.... :biggrin:

    I'm flattered :redface: , but no, something like this rule has been known for ages so isn't my invention at all :smile: The astronomy guys have plenty of web pages on the subject, for example.

    Thanks Paul. I have a feeling that my Bigma and TC's will be for sale soon as I am doing mainly portrait shots now.

    I think an average tripod would not fair so well. For these shots I am using a heavy surveyors tripod. That combined with mirror lockup, remote released helped considerably. I was never able to get that kind of detail from the D70 and believe it was due to lack of MLU. I have pictures of my tripod setup if anyone is interested.
     
  14. Well I'm not up to it against the experts, but I figure you cannot shoot fast enough with a dark object like the moon and with a huge lesn like the Sigma 800mm F5.6. I try to use spot metering and one stop under max aperture to get decent sharpness for my moon shots ( I figure depth of field is not really an issue at the distance we have to the moon :)).

    Here are a two with the D2H and the Sigma 800.
    40997576.
    and
    51028094.

    I've spent quite a bit of time doing astrophotography at Mt Wilson in Los Angeles. I use my F100 and ISO 100 film but I think the settings should carry over for digital:
    (BTW my scope is a 1000mm F/5 so all settings are based on that)
    Cresent Moon- ISO 100 1/4
    Quarter Moon- IS0 100 1/30
    Full Moon- ISO 100 1/60

    My mount tracks so I don't have any issues with blur, but if I were shooting my D2x and using a stationary tripod I would up the ISO to 400 and adjust the shutter speed accordingly (e.g. Cresent - ISO 400 1/15, etc).

    Hope that helps
