The planet Saturn, with details could hardly see our eyes. You can see the
Cassini Division separating the rings as well as details of its turbulent
surface. Date: April 6, 2012. (Credit: Fernando Silva.)
The red planet is revealed in detail for the CCD
camera Fernando Silva. The polluted skies over the city of Santiago de
Chile are not an obstacle for the astrophotography captures the details of the
Martian surface.
Using a telescope Celestron Nexstar 127 SLT, a
Maksutov-Cassegrain with focal radius of 12, ideal for capturing planets and
planetary camera of the same brand Reimage, Silva took videos of these objects
with little exposure to then add several frames in register.
With
patience, method and art, the author managed to spectacular results wanted to
share with our readers.
The method of "stalking" to add frames in
registration allows circumventing the problem of field rotation that occurs in
telescopes alt-azimuth mount, as the Celestron Nexstar models.
