Image Description and Details : CG4 means “Cometary Globule #4” and is a complex of nebulosity and dust with a very peculiar shape (it looks like a concentrate of comets) located in the southern constellation of Poppa. The “head” of the galactic worm has dimensions of about 1.5 light years, while the offshoot that follows the head and which is directed in the opposite direction with respect to the rest of the famous Vela supernova (which is at the center of the huge GUM nebula), it has a length of about 8 light years.
The complex was photographed during ShaRA#4 project; this is a composition of 3 different images in wide field taken with the T3 from Chilescope Service (a very fast 500m f/3.8 Newtonian), processed by Christian Privitera, Andrea Iorio and me (Alessandro Ravagnin).

Image Description and Details : 13 x 90 sec IR and RGB video captures of Saturn (~ 1 hr) were made under very good seeing conditions.
The narrowing of the rings since last year is very clear, so it is pleasing to see a hint of the Encke Division. The Southern Hemisphere is more active than the north, as it receiving more sunlight than before and a particularly large system is evident in the STrZ to the p side of the Central Meridian. The colours of this region that have emerged as the planet's tilt allows a better view are astonishing and beautiful. I have not altered these in any way, save for a balancing of the histograms.
The moons Tehtys (left) and Enceladus (right) were close to the planet and some time later Tethys and its shadow transitted the southern Hemisphere of the planet.
