While each of us live our day to day, there are thousands of small bodies beyond Neptune orbiting the sun tirelessly. This work is about seven of those dwarfs planets. In the summer of 2012,...

ISON Comet Sun Flyby During the last two days, we have been following with particular attention the ISON comet through pictures of SOHO / LASCO. We have composed this video using pictures of the C2, C3, Stereo and a simulation  with Stellarium software. This task was quite complicated due to severa...

This is the first time I post a photo in this forum. I'm not sure if this is the the place and the way. Sun spot on May 9. Meade LX200-R 8" Telescope with 4X powermate and a IMG132E ccd camera from Lunático astronomia. I Hope you like it. Regards http://laazotea.org/sites/default/files/2012-05-...
