... 5000/6000 light-years away

M17 (Messier 17) , the Omega nebula

 

I'm not completely satisfied, but it is a first attempt! only 1 hour total exposure! I hope to photograph it better soon and with more integration time, before the end of the summer!

 

this is about 10 shots in dual iso 1600/2500 with a CDS Canon 50D on a 130/910mm super-apo triplet. taken from Italian western alps (cugn di goria, colle di sampeyre, 2500m)
