This paper presents 2109 times of minima for 965 objects acquired by 59 members and cooperating observers of the Variable Star and Exoplanet Section of the Czech Astronomical Society (B.R.N.O. Observing project).These observations were submitted to the website of the Variable Star and Exoplanet Section of the Czech Astronomical Society between November 2016 and March 2018.

In this article, the period-luminosity (P-L) relation is determined of delta Sct stars, based on a strictly selected sample of 483 stars from the OGLE-IV Galactic bulge fileds, together with 547 delta Sct, of which 52 are high-amplitude delta Sct stars (HADS) from the CzeV catalogue using Gaia DR2 parallaxes and apparent magnitudes. Absolute magnitudes were corrected for interstellar extinction using the Planck thermal foreground dust maps and the 3D Bayestar probabilistic dust map. Where possible, the CzeV catalogue periods were compared with photometric measurements from the TESS mission.
