| Notes | After viewing M57 with two members from my local astronomy club, I decided to sketch M57 before it got any closer to the horizon this year. The Ring Nebula gave off a slight blue/green color with a darker core area. I was not able to see the central star in this planetary nebula but was able to see the faint star to the west of its ring shaped cloud. After my initial observation, I used an Oxygen III filter to see more of the color and cloud formation in M57. When using the OIII filter the central core seemed filled in more and the color had a darker hue, which made it more visible. The cloud itself also seemed fuller when using the OIII filter. However, I felt that the image was sharper without the filter. The sketch was made without the filter in place. |
