Description

Most of the data used in this image came from the AP 130 GTX listed above. However, I must admin that a certain amount of detail at the core of the nebula was taken from a much earlier image generated with my Celestron 9.25 HD. The much narrower FOV and accompanying higher resolution did add definition to the lace-like structures, impossible to resolve in the wide-field image.
