Observations at the TNG can be proposed through the
Italian Time Allocation Committee (TAC) which assigns, based on the scientific merit of the proposals, 75% of the available time. The rest of the time is at disposal of the Spanish and international astronomical communities. The TNG is open to new

The interface between the telescope fork and the instruments at both
Nasmyth foci is provided by two rotator/adapters. Their main function is to compensate for the field rotation by a mechanical counter rotation. The best quality of the TNG is that all the available instruments are permanently

mounted at the telescope. This guarantees flexibility during an observing session, since it is possible to change instrument during the night with a loss of time limited to a few minutes.
