Abstract

We present technical, instrumental, and software upgrades completed and planned at astronomical observatory called "Osservatorio Astronomico Regionale Parco Antola, Fascia" (OARPAF), hosting an 80cm, alt-az Cassegrain-Nasmyth telescope. The observatory, located in the Ligurian Apennines, can currently be operated either for scientific (photometry camera) or amateur (ocular) observations, by switching the tertiary mirror between the two Nasmyth foci using a manual handle. The main scientific observational topics are related up to now to exoplanetary transits, QSOs, and gravitationally lensed quasars, and results are being recently published. A remotization and robotization strategy of the entire structure (telescope, dome, instruments, sensors and monitoring) have been set up and it is in progress. We report the current upgrades, mainly related for what concerns the "hardware" side to the robotization of the dome. On the instrumentation side, a new modular support for instruments with spectrophotometric capabilities is on a preliminary design phase, improving the telescope performances and broadening the potential science fields. In this framework, the procurement of spectrophotometric material has started. On the software side, an innovative web-based software relying on websockets and node.js can already be used to control the camera, and it will be extended to manage the other components of the instrument, of the observatory, and of the image database storage.
