Commissioning of the instrumentation and launch of the scientific exploitation of OARPAF, the Regional Astronomical Observatory of the Antola Park.

The OARPAF telescope is an 80cm diameter optical telescope installed in the Antola Mount Regional Reserve, on the Ligurian Apennines in Northern Italy. We present the the improvements and interventions that have been implemented since the inauguration. The characterization of the site has resulted in a typical background brightness of 22.40 mAB (B filter) -- 21.14 mAB (I filter) per arcsecond squared, and a 1.5 -- 3.0 arcsecond seeing. An estimate of the magnitude zero points for photometry is also reported. The material under commissioning foresees 3 CCD detectors for which we give the linearity range, gain, and dark current; a 31 orders \'echelle spectrograph with R 8500--15000, and a dispersion of n = 1.39 x 10^6 lambda + 1.45 x 10^-4 , allowing radial velocity measurements up to 15.8km/s; and a long slit spectrograph currently under commissioning. The scientific and outreach potential of the facility is proven in different science cases, such as exoplanetary transits and AGNs variability. The determination of time delays of gravitationally lensed quasars, and the tracking and the study of asteroids are also discussed as prospective science cases.
