* Brought into Photoshop: Zoomed image overlayed onto main image

* Annotation

* **Zoomed in version:**

* Duplicate L and RGB images before stretching

* DynamicCrop on M87

* ArcsinhStretch (This stretch is less aggressive than the one from the main image, in order to show the jet from the black hole)

* LRGBCombination

* CurvesTransformation to boost color saturation

* Zoomed in image overlayed with the main one in Photoshop
