Star Finder

Improved the star finder now out puts the number of stars allong with the coordinates of all the pixels in the stars

Tested on on of Beki's simulated images with no background

Screenshot_2017-11-10_01.15.50.png

It finds that there are 48 stars, there are 47 stars and the image has a white line on the right hand side which is abvoe threashold so it's counting that as the 48th star

I also found the backgroud for one of the real image using the 65X65 box but this took 40 mins to run so I didn't get a chance to plot it.

next step will be to do the aperture photometry and to optimize the background algorithm so it can be useful.
