Purpose: to become familiar with the image analysis program and to develop an understanding to the size and age of planetary nebulae
The first part of the experiment involved using a picture of a church and back round to understand different pixels, ADU, zoom, and how to get the (x,y) coordinates. We then took this brief understanding of pictures and applied it to the stars. We loaded a picture of nebulae m42. After this we needed to calculate the average number of stars or solar masses. We found the (x,y) coordinates of a position in the center of the nebulae and on the edge of the nebulae. We used the following distance formula to find the distance between the points.
After this calculation the answer in pixels needed to be converted to arc seconds for use in the small angle formula where 1 pixel approx. = 3 arc seconds. We now could use the small angle formula to find the actual radius in pc. Where d is the radius D is the distance fro...
