+#### What is the angular resolution?
+- Any image-forming device like a telescope can be used to recognise small details of an object. Hence, the smaller the angular resolution, the better the formed image as it can focus on smaller and smaller details.

+**_SO THE GOAL BECOMES HOW TO MAKE IMAGES WITH SMALL ANGULAR RESOLUTIONS._**

+It seems that in astronomy, there is a relationship between the image resolution $\theta$ and the wavelength
+$\lambda$ giving by $$ \theta = 1.22 \frac{\lambda} {D} $$
+- Where $D$ is the diameter of the telescope.
+- to get better resolution (small $\theta$), we need:
+	- Large lenses ($D$)
+	- shorter wavelength $\lambda$
+- Therefore, as $\lambda$ increases $\theta$ also increases making the image less detailed.
+- Be careful that larger image resolution does not mean better images

 - This is where an image gets exposed for a very long time to detect fainter objects in the sky.
 - The idea is that the longer you wait, the more you collect signals or frequencies for fainter objects. We can see the following simulated image better as we increase the integration hours.
