Of all the topics in astronomy, nothing seems to
garner more interest than astrophotography. Let's
face it, the Universe is replete with objects and
phenomenon that defy the ordinary and offer some of
the most spectacular photography ever seen.
For example, you may want to look at the
Messier page
for some great images - or even check out our
Image Gallery.
For more advanced CCD techniques and resources,
go straight to the
Advanced Topics.
I am one of the purists: trained in photography
and imagery, my job uses a wide variety of
photographic and imaging equipment. I cringe at the
thought of easy "point-and-shoot" cameras, but I am
well aware that the images produced by these devices
are acceptable. What's even more cringing is the
thought that
CCD and computer technology make the
would-be photographer believe that anyone is capable
of capturing wonderful, professional quality images.
Nothing is farther from the truth.
Photography is an art, regardless of whatever
technology is used to drive it; but that does not
mean every cannot be a photographer. There are three
very important factors in the creation of a
photographer:
- Patience
- Experience
- Patience
Yes I said patience twice - and photographers
know what I am talking about. Ansel Adams is
arguably one of the finest photographers that has
ever lived:
This 1966 images of Scripp's Pier demonstrates
his ability to use light and shadows to enhance the
finest details while providing a panoramic overall
view of the subject. He also uses some of the finest
photography equipment available. But what is little
known is that he has been quoted saying "often I find
only one usable image from an entire roll of film."
This is what I mean about patience. Regardless of
experience, factors outside the control of the
photographer greatly influence the overall result.
In my world of medical imaging, I also teach others
the tips and techniques involved with my photography
(I have some very impressive images of the human
retina - if you want to see them, let me know). Of
all the things I teach, I say this: the
photographers skill only accounts for 20% of overall
image quality - quality of the subject,
environmental factors and equipment status account
for the rest.
This
section on astrophotography will introduce the world
within a world that provides not only valuable data,
but some very impressive images as well. Be sure to take a look at the

Resources for more information, and feel free to
