Remarks: |
More information about the discovery of this PN can be found at here or here . The color image is highly contrast enhanced so that the exellent resolution of the raw image data is not completely visible. The OIII-data was only applied to the blue channel of the image. The inverted images below show the real intensity distribution in the HII and OIII light at a 100% resolution. In the HII-Image two other ring segements are indicated at 8:00..9:00h and at 2:00..3:00h DDP was used. Eleven years later we did a primary focus image of Ju 1 (how this PN is officially called since 2013) together with Abell 69 and P Cygni. See here. |
