The INSIDE  (Scientific-Technical Infrastructures and Institutional Services for the Strategic Development of the Canary Islands Observatories) Project – Phase 2 includes the following actions:
1. Advanced instrumentation for telescope facilities: Developments related to the WHT (William Herschel Telescope), HARPS3 (High Accuracy Radial Velocity Planet Searcher 3), HORuS (High Optical Resolution Spectrograph), Laser Star Guide, and QUIJOTE (Q-U-I JOint TEnerife CMB experiment).
2. Improvements in telescope operations and observation programs: Developments related to the TCS and IAC80 telescopes.
3. EST (European Solar Telescope): Preliminary design of the adaptive optics and calibration systems, as well as the preliminary design of the building and dome systems.
4. Strategic technical services and infrastructure to support the scientific exploitation of the Canary Islands observatories (includes equipment for adverse weather and fires, improvement of electric power supply, atmospheric characterization)
