Night Twentyseven- The Western Veil Nebula

-
Set up the telscope in my driveway last night with a Northern target. This is the Veil Nebula. It is a supernova remnant. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of the explosion, the supernova would have appeared brighter than Venus in the sky. The Veil Nebula is expanding at a velocity of about 1.5 million kilometers per hour which is 932,000 miles per hour. Using images taken by the Hubble Space Telescope between 1997 and 2015, the expansion of the Veil Nebula has been directly observed.

The new Dwarf 3 telescope has arrived

 After a 6 month wait the new "smart telescope" has arrived.  There is no eyepiece to view the celestial objects. Instead, the telescope is linked to your phone or tablet for viewing and images are downloaded when you connect the scope to your desktop. Dwarf 3 telescope First night's images: The Andromeda Galaxy This galaxy is approximately 2.5 million light years from Earth.  Thought to be about the same size as the Milky Way Galaxy and it's headed our way. Should arrive in 4 to 5 billion years. Few actual collisions are expected as the stars are so widely distributed with the final result being one much larger galaxy. This is the only object visible to our naked eye that lies outside of the Milky Way. Everything else we see at night, lies within our own galaxy.  Here is the same image as it comes off the telscope with zero processing.  Here is one more image with the number of background stars reduced through processing.
