This project holds an iPhone 13 with the case on (modify if your case is thicker) allowing the charging port to be accessible for charging during Astrophotography (I use Astrohopper). The phone stays in place when rotated up to 80 degrees in any direction. You can put 2 elastic bands around the phone and holder at the top and bottom of the phone so it does not fall out if you tilt the holder greater than 80 degrees.
Modify the width, length to custom fit your phone. Making the phone area longer might require you shortening the dovetail.....
