|2015-6-08: First Summer Astrophotos! ⬅︎ |
|Four of the very cool targets we imaged last weekend here at Starry Hill:
Lagoon Nebula/M8 - a giant, bright star-forming region in Sagittarius, close to the center of our
Dumbbell Nebula/M27 - the remains of a dead star (planetary nebula) in Vulpecula. Our sun may
look something like this when it dies. Notice the
white dwarf at its center.
Hercules Cluster/M13 - a globular cluster with about 300,000 stars in the constellation Hercules.
It is outside our Milky Way Galaxy but closely orbits it.
Pinwheel Galaxy/M101 - a face-on spiral galaxy about 21 million light-years away in Ursa Major,
just above the end of the handle of the Big Dipper.
Each of these photos consists of about thirty individual photos called subs that were stacked
(combined) to reduce noise. Each sub took 30 to 60 seconds of imaging time depending on the brightness
of the object.
We used a Canon DSLR and a relatively small 5" telescope.
