Name: |
M1 (Crab Nebula) |
|
Type: |
Supernova Remnant & Pulsar Wind Nebula |
|
Description: |
Ever wonder what is left over after a super nova explosion? Well the Crab
Nebula is a spectacular example of the remains. Here we see an ever
expanding cloud of gas that used to be the outer regions of a giant star. In
this case the remaining inner core has collapsed into an extremely dense
neutron star. This picture was taken with an Orion Starshoot DSCI II,
Nikon TC-301 2x Teleconverter , and a Nikkor 600mm f4 ED lens. |
