Observations of PS1-3PI J000743.48+803318.0

 The star PS1-3PI J000743.48+803318.0 is a variable of the RRAB type, according to VSX.

This is a rather faint star and, probably, near the limit of my setup (150mm Newtonian with a focal length of 750mm).

The star is located in the V965 Cep field, which I observe regularly. For measurements, I used stacked images with a total exposure of 10 minutes (usually, stacks of 20 images, 30 seconds  each).

The following phase diagram presents observations from July 2022 to April 2024.

These are "Unfiltered with V Zeropoint" magnitudes.
