BUBBLE TROUBLE:
I would like to quote one of my favourite heroes, famous Dr. Fredrick Fronkensteen (from the 1974 American
Comedy Film “Young Frankenstein”): “No.
No... Be of good cheer! If science teaches us anything, it teaches us to accept
our failures, as well as our successes, with quiet dignity and grace!” (I
feel as though this shot is more of a failure than a success! ...But it does
serve as a great learning experience.)
NGC7635, The Bubble
Nebula, is a faint emission nebula that floats above the “w” in the
constellation Cassiopeia. The
"bubble" is created by stellar wind from the young central star who’s
mass is thought to be up to 40 times that of our Sun’s! The
top left corner of the image shows 11th magnitude open star cluster
M52.
If I would have
studied the object’s specifications a little more prior to shooting it, I would
have realized how dim it is. This would have prompted me to increase the
exposure lengths, which would have resulted in a brighter image. Much of the
red nebulosity that floats around the central bubble is missing in my picture. The
good thing is, the perimeter of the bubble is still evident. ...Don’t let this
image represent all that God had intended us to see, when he created the Bubble
Nebula. He had much more beauty in mind. Try this link to see a great shot from another amateur astro-photographer:
