FEATURED IN OCTOBER

IC410 and NGC1893 – Emission nebula and open cluster

Welcome to the Le Ciel Astro - CCD website. The site is dedicated to the astrophotography of deep sky objects and the solar system (planets, Moon and Sun). The purpose of the site is to share technical experiences in the field of astrophotography. 

Several images of objects from the deep sky and the solar system are exhibited on the site. There is the presentation of the equipment as well as the technique used to take the photos. 

The site presents the software used to acquire and process the images with an Internet link to help you obtain this software. Several other Internet links in the field of astronomy are also presented.

Hoping that the site will be of use to you for the realization of your images of objects of the deep sky and the solar system.
