Before the
invention of photography observers sat at
|
|
|
telescopes and
sketched what they saw.
|
|
|
• |
Combining the
optics of a telescope with a specially
|
|
|
constructed
camera to make the first photographic plates took
|
|
|
place around
the 1840s.
|
|
|
• |
By the turn of
the 1900s astronomers turned their attention to
|
|
making
telescopes specifically for photography and not for
|
|
|
observing.
|
|
|
• |
This in turn
led to even better imaging of galaxies and star
|
|
|
clusters as
well as better spectral images for deeper scientific
|
|
|
analysis.
