Description

Evaluation des possibilités du logiciel APP
Mosaïque de quatre groupes de 30 images. Traité de bout en bout avec APP (stacking et assemblage en une seule opération). Les aberrations du 85mm sont encore présentent, j'espère faire mieux une prochaine fois.

Une partie de la Grande Ourse avec ses étoiles les plus brillantes.
N'hésitez pas à tenter le mode "pleine résolution". On peut discerner la silhouette de certaines galaxies et une nébuleuse planétaire.
Photos prise un soir où la lune était presque à son maximum :)

Part of the Big Dipper with its brightest stars.
Don't hesitate to try the "full resolution" mode. The silhouette of certain galaxies and a planetary nebula can be discerned.
Photos taken when the moon was near to be full :)
