The result is quite promising, so we just imagine the performance it could deliver when we'll get it perfectly tuned ...and that might be any soon!

First Light for the Planewave Telescope !
The new 50cm Planewave telescope (that we refer to as T500) is still not formally aligned, and still not even perfectly collimated, though we managed to take a first astro picture, namely on the Omega Centauri globular cluster.
The result is quite promising, so we just imagine the performance it could deliver when we'll get it perfectly tuned ...and that might be any soon!

May the 9th, Transit of Mercury:
success again...
The previous Transit of Mercury happened on november 2006... Ten years after, we succeeded again to watch the current one, without even needing any travelling: this time it happened at home, in Vicuña, and so we observed it from the Great Solar Observatory of Chile (GOSCh).
While still in progress, we are publishing the first shots of the event...
On the rising Sun, can you glimpse the subtle dark spot of planet Mercury, on the lower left of the Sun disk ?
When higher in the sky, the tiny black dot of Mercury comes easier to see...
The following view is processed as to show some prominences that arise from the chromosphere (that thin red ring surrounding the Sun globe): two of them are visible to the lower left of the disk.
Meanwhile the dark, sharp tiny disk of Mercury keeps going on...

camera Canon 60D - exp: 1/4000 sec. ISO 100 Below is a much classical view of the Sun obtained through a white glass filter. The disk of Mercury approaches its exit (to the lower right) and still appears with a much higher contrast than the small group of sunspots visible above the center of the sun disk.
