I really like this one. Thor's Helmet is an emission nebula in
Canis Major, near Sirius, the brightest star in the sky. It is about 30 light years in diameter.
I've done this before but this is much better.
NGC 2903, a galaxy in Leo, about 30 million light years out there.
I added more subs to the Cone Nebula, nearly 2 hours of exposure now.
