About
Welcome to my site dedicated to astrophotography.
This site is a feedback based on techniques used with my own equipment and borrowed to most other experienced amateur astronomers. It largely presents my photos of deep sky, planets and sky with the description of the different techniques used to achieve them and the associated equipment.
Like many of you, astronomy passionate me since my childhood. The show of eclipses of the Sun and Moon with the visit of the magnificent Hall Bop comet in 1997 amplified this budding passion.
Following a one week internship in astronomy conducted in 2006 at the "Ferme des étoiles" in the Gers state, I gave in to the temptation to acquire a mount and a telescope with the possibility of evolution towards photography then. This learning period in visual, necessary before going to the astrophoto, allowed me to better control the spotting of the constellations and the objects of the deep sky as well as to be familiarized with the adjustment of the material (centering of the polar viewfinder, collimation of the telescope, alignment of the mount, ...)
Then, the period of visual observation has quickly given way to astrophotography because I wanted to keep track of what I saw and, moreover, in color. It is at this point that complications began ...
I started astrophotography in 2009 with a color planetary camera but more seriously since 2011 with a "filter replaced" DSLR camera where I learn and practice techniques from other experienced amateur astronomers present on forums where I contribute also with my rise in skills.
For some time now, I have been taking more and more pictures of nebulae with SHO or Hubble color filters from my new cooled monochrome camera because I find that they bring even more contrast and color with an artistic touch that makes them a little more spectacular. In addition, these filters allow to get rid of a little light pollution. On the other hand, the exposure times are longer and the treatment more difficult.
My home, and therefore my default acquisition site, is located on the outskirts of western Toulouse with light pollution equivalent to an suburban sky. But I am fortunate that my town as well as a few others in the area turn off their public lighting from 23:00 pm to 5:30 am which allows a significant reduction of this pollution.
Feel free to email me for any comments or questions about the different topics covered on this site.
Good visit !
