Messier 17 - Omega Nebula

  I think I could have benefited greatly from more subs on this one.  I ended up getting all .fits instead of raws on the 1st night.  The second night, MaximDL hung on downloading one of the raws, then the trees took over and I lost the autoguiding star.  I will try to add more sometime this season.  This nebula grabbed my interest simply because it was near Pluto (more on that object later).  I really like it.  Despite only 4 subs for a total of 14 min I think it came out well.

I think I'm the kind of person who doesn't like strong opinions.  It doesn't matter if I agree with your opinion or not, it's not factual, it never will be 100% factual and I don't care for it.  That's probably why I hate politics.

I've always loved facts, provable facts of nature and things concerning science.  

Over time, I found that most facts are mostly reference and it was the creation of and discovery of new things that intrigued me.

"A good friend once told me you are our memory
without them we equal nothing
And all I can see is the place I wanna be
Suddenly my life was so free
Leaves at my feet, blown to the ground
their echoes are reaching my ears
Nights coming fast, suns going down" - A7x
