A photograph of the satellites of Uranus.

This photo was taken with a Hokenn  200/1000 telescope. The camera was a Meade DSI Pro. I used the Envisage program. Do not use with the "planets" function. Use the "Deep Sky" function to see the satellites of the planet. They see the original photo, a photo cutout, a map taken from Stellarium program and a photo with arrows showing the satellites of the original photo.

Hello! He spent a long time since the last photo. This happened because I had personal problems. Today I upload a photo of the lunar crater Copernicus. Not a good photo, but the lighting of the sun can see very well the emission of matter from the point of impact. Hope you like. It was taken on 12/04/2012 at Buenos Aires time 0h30m.
