The fan-shaped cloud that extends northward from the bright, illuminating star in this frame is called Hubble's Variable Nebula. As dust swirls in the immediate vicinity of the star, it casts shadows on the walls of the large shell, resulting in an ever-changing appearance.
This time-lapse GIF uses images that I have taken about weekly for the past six months.
It will be too close to the sun to observe for the next three months, but will return in the pre-dawn sky in August.
Images were taken with a 12 1/2" f/6.7 Dall-Kirkham telescope from my backyard in Tempe. They are typically averaged 5-minute exposures with an SBIG STXL-6300 camera that produces an image scale of 0.88 arcseconds per pixel. I doubled the image scale in post-processing so viewers don't have to lean into the display so much.
