QATAR-1 Light curve

Using 3 hours of data from the micro observatory in arizona, and 1 hour of total exposure data, I plotted the following partial transit light curve for the 1 planet of the system. Qatar 1-b is a planet 1.09 the mass of jupiter. Yesterday 15/5/16 it had a predicted transit.

The yellow region indicated the predicted transit. Notice  how the trend is falling, that is probably due to the fact that I had the data of half the transit.


Here is a 1 min sub of the star field, Qatar 1 is encircled.


and here is 48 minute stacked exposure of the star field I made using the images.
