This M33 picture, lost in my hard disk since October, got finally my attention. This is by far the best M33 I have ever pulled out.

NGC4565



Edge-on spiral galaxy, aka Needle Galaxy, located some 30 to 50 million ly away, in Coma Berenices, was first spotted in 1785 by sir William Herschel.
Some other DSO's can also be seen in this galaxy rich neighborhood.

M101 Pinwheel Galaxy


The Pinwheel galaxy, also known as Messier 101 (M101) located in the Ursa Major constellation lies some 25 million light years away from us, was first discovered on March 25th, 1781 by Pierre Méchain, who later informed Charles Messier.

M51 before and after SN2011 dh


M51 animation, before and after SN2011 dh.
Different exposure times between the two pictures make stars look brighter, though this is not true...

Supernova SN2011 dh in M51


This is my first Supernova!
I used my Taka 4" at native f/8 focal length and SBIG's ST2000XM detector. Six 300" exposures aligned and combined in MaxIm, with DDP filter. Post processing in CS4.
