NGC 7424 |
|
Info |
NGC 7424 is located in the
constellation Grus. This face on spiral barred galaxy is about 40 million
Light years away from us. It is about 100,000 light-years across making it
remarkably similar to our own Milky Way. Throughout the arms, many bright
bluish clusters of massive young stars can be found. The star clusters
themselves are several hundred light-years in diameter. Massive stars are
born in the arms of NGC 7424, they also die there. This galaxy was host to
a recent super nova event, SN 2001ig, which has well faded and can not be
seen in this image. |

Notes/ Conditions |
Conditions- It has been rather a poor winter/ spring.
Taking the lum, conditions were on both occasions poor to very average.
Also, the same is the case for the colour. Still it was good to be able to
get out! |
