Hi guys!
at first I apologize for missing here so long... job and family and "clouds" kept me away from astroimaging for a while, though I usually pass here for a quick look and found a lot of beautiful images.
Here a result that makes me proudly, a "live joint imaging" session taken last year with my friends Alessandro Falesiedi and Mario Lovrencie, using our 3 scopes:
• Alessandro F. : C11HD@f7,2 con Takahashi Reducer + Avalon M1
• Mario L.: Newton selfmade 10 f4 + mpcc + AZ eq6
• Elio : RC + GSO reducer 0.7 + canon 60d cooled + Avalon M1
total exp. time L: 13h – RGB: 7h
Abell 2151 is the code name of this spectacular cluster of galaxies in the constellation of Hercules whose light took around 500 million years to reach us : the time "emerged land" still floating on fluid magma on our planet , about 250 million years before the dinosaurs!
It 'a fascinating area of the cosmos filled of galaxies which interact with each other in collisions, mergers, or gravitational distortions where we can clearly distinguish the galaxies with high star formation hued blue to those with older populations dominated by yellow, a huge stellar "neighborhood" which extends for about 2/3 million light-years!
With overall integration has been reached galactic mag around the 21, and able to highlight a particular object, so much the name Quasar (almost stellar radio source) the core of an active galaxy, cataloged as QSO J1605 + 1745 with a redshift of z = 2.99 which leads to a calculated distance of between 7 and 10 billion light years, almost to the origins of our Universe !!!
Take a look
on my website, there's a comparison made with the unreachable image taken by Ken Krawford, just for joke...or not!
Thanks for looking and feel free for comment, you are always
Cheers
Elio
