Changing Nebulae

Here's a companion piece to Jim Thommes' fine M 78.
There aren't too many nebulae that change appearance within a human's lifespan. McNeil's Nebula, next to M 78, is one and NGC 2261, known as Hubble's Variable Nebula, is another.
Attached is a mid-sized image of NGC 2261 that I just finished.
A larger image and explanation for the variability can be found here:

Thats a great image dan! You must have had some good seeing for that one. The nebula must have undergone a change recently as just 18 months ago I saw it in my 20" much like Jeff's image. Now, its only a sketch but I tried to be as accurate as possible. Very cool to see stuff change......
