Results & Observations of Image

Activity 4 Questions:
  1. Describe whether or not you feel manipulation of the image was helpful or not helpful to you in looking for new information in the Supernova Remnant (SNR). Be specific with examples from your observation notes.
  2. Elaborate on which of the image manipulations was most helpful and what resulted from that manipulation of the SNR image.
  3. Evaluate the effectiveness of manipulating this image versus the other 3 images. Was manipulating this image more or less helpful in looking for new information in the SNR image?
  4. Explain if there was anything visible in the image after manipulation that was not visible to you before manipulation. If so, what does it appear to be?
