I used a Nikon CoolPix P900 camera to take the shot. No telescope was attached to the camera.
I then used the PhotoScape freeware to process the photo. By applying its backlight correction, I could brighten the dimmer Saturn relatively to the brighter surface of the moon. As a result, I could make Saturn visible, while preventing the image of the moon from becoming saturated.
Although distorted in its light distribution, the image is very interesting and informative.
Here is the best image I got from the moon-Saturn conjunction.
It was taken at 00:16 (UTC-3h) on June 19, 2019, when Saturn was 3490.2 times more distant from the Earth than the moon. The centers of Saturn and the moon were only 25.8 arcminutes apart.
