    Default Canon 10D vs. Nikon D70 for astrophotography



    >

    A couple of comments:

    1. Hack code... Doesn't seem like a reasonable alternative for normal folks.

    2. I did take the time to read the Dpreview link you provided as well as
    re-read the S&T article. Someone pointed out that neither seemed to have
    actually done any deepsky imaging with the D70. Have you found some evidence
    to the contrary? Otherwise it seems one would have to be pretty skeptical of
    any conclusions based on these articles.

    Yeah, the same S&T published article where an achromat was measured
    having better control of chromatic aberrations than a true APO triplet
    !
    Bottom line, it is the person who writes the article who makes the
    call.
    Editors in S&T may or may not catch the obvious blunders. In this case
    I think Johhanes fell the victim of pressure to include all available
    cameras and judge them for astrophotography without really having any
    hands on experience. Many people drummed up Nikon as good for long
    exposure but as far as I know only Buil has made a controlled
    evaluation/comparison.
    I've been Nikon fan for all my life, still have three film bodies and
    a small fortune invested in Nikkors, but for digital I've made a
    switch to Canon. After Nikon released D70 I started to regret, but
    Buil has been very convincing in his arguments. Plus he has nothing to
    gain or lose from bashing the either company - I have absolute faith
    in his findings.

    I'm afraid at this point in time and for this purpose (long exposures,
    very low light), Nikon is faling behind Canon. Plain and simple.

    >I would tend to believe S&T's assessment more than some translated document

    "Some translated document" vs two respect journals...

    1. "Some translated document" = Christian Buil, author of one of the original
    books on CCD astronomy, author of the Iris image processing software and
    someone who obviously has the technical expertise to understand the inner
    workings of a camera like the N-70.

    http://astrosurf.com/buil/

    2. Respected journals = two commerical magazines. S&T and Digital Photo are
    not "journals", there is no peer review process that are an important part of
    any journal, these are commercial magazines that garner a certain amount of
    respect.

    For astrophoto purposes, though, you are right: the mirror lockup is
    the #1 change. And one that can be effectively simulated by removing
    a cover, so its not that big a difference in the end.


    Modified 300D for astro-photography:

    The bad news:

    .... $1500.

    The price is not the only bad news. On top of paying up to $900 extra for
    the modification, one must also give up any warranty from Canon. This means
    that if your camera self-destructs in one week, you've got nothing.

    An insane option, IMO. This camera is fundamentally intended for "normal"
    imaging. With this mod, you give that up, you give up the warranty, and you end
    up with a total investment in the same range as you could get a proper
    astronomical imaging camera for anyway. While the 300D does a better job at
    astroimaging than any other digital camera I've seen, it still doesn't come
    close to what a good, cooled, B&W astrocamera is capable of.

    Agreed. Add to the list that you also lose autofocus, which is a
    major reason to own EF lenses in the first place.

    A few examples of my simple astrophotography with an unmodified Rebel
    (which also demonstrate the lack of red sensitivity) may be found
    here:

    If you're willing to put up with the lack of red sensitivity, the
    digital SLR's are fine for simple camera-and-tripod astrophotos, while
    also being excellent for daytime use.

    Chris, where did you find a Digital Rebel body for $600?
