Hi everyone ! I have created this new blog to share more easily my comments about the world of planetary astronomy. Even if I'm already an experienced observer, there are always things to learn and products or techniques to test and I hope to share this here. I will also post informations about the events I'm attending regularly and other stuff. Planetary astronomy today is becoming again a dynamical domain of observation so let's improve and share our passion !
