Pourquoi un nouvel Atlas<\/strong>…
Astronome amateur depuis une bonne vingtaine d\u2019ann\u00e9e et appr\u00e9ciant particuli\u00e8rement l’observation visuelle au t\u00e9lescope, j\u2019ai rapidement constat\u00e9 \u00e0 mes d\u00e9buts que pour approfondir la d\u00e9couverte du ciel, les observations spontan\u00e9es n’\u00e9taient pas la meilleure approche et qu’il \u00e9tait donc pr\u00e9f\u00e9rable d’\u00e9laborer une m\u00e9thode d\u2019observation.<\/p><\/div><\/div>

Pour cela se r\u00e9f\u00e9rer \u00e0 diff\u00e9rents ouvrages afin de pr\u00e9parer sa petite fiche ou liste d\u2019observation constitue une d\u00e9marche logique. Dans ce but, les atlas du ciel sont d\u2019une aide pr\u00e9cieuse, cependant la plupart d\u2019entre eux sont organis\u00e9s suivant un d\u00e9coupage de la voute c\u00e9leste en diff\u00e9rentes cartes selon le syst\u00e8me de coordonn\u00e9es \u00e9quatoriales.<\/p>

Pour l\u2019observation visuelle avec un dobson, donc une monture azimutale, je trouve que l\u2019exploitation de ce type d\u2019atlas n\u2019est pas naturelle. De plus, lorsque l\u2019on apprend \u00e0 se rep\u00e9rer dans le ciel, la premi\u00e8re chose que l\u2019on identifie, est le dessin des constellations, form\u00e9 de lignes fictives.
Finalement, avec la pratique, c\u2019est bien la reconnaissance de cette \u00ab signal\u00e9tique \u00bb qui fixe notre attention et nous permet d\u2019orienter rapidement notre t\u00e9lescope. Pour moi cela reste une approche plus simple et plus spontan\u00e9e. J\u2019ai voulu aujourd\u2019hui au travers de cet \u00ab atlas des constellations \u00bb, r\u00e9aliser un guide d\u2019observation \u00ab sur mesure \u00bb plus adapt\u00e9 \u00e0 l\u2019observation visuelle sur le terrain.<\/p>","protected":false},"excerpt":{"rendered":"
