Floodfill algorithm improvements
- To improve our algorithm we defined a star to be anything above 5 pixels in size.

- This shows an attempt at removing the background from the image.
- This shows an attempt at removing the stars from the image. Note the image is logged, in order to better see the remnants of the stars.

Stacking
- In order to reduce errors and create better contrast between stars and background, a preliminary stacking effort was performed for 6 images taken in location 1, the result of which can be seen below.
- From this it appears that although some movement is expected across the images, their overlay does not exhibit any easily noticable affects caused by this. Note however no scientific analysis of the effects has been conducted thus far.
