The optical axis of a Nasmyth telescope should be perpendicular to the Elevation axis and pass through the rotational center of the Tertiary mirror turret rotator. Realized by aligning a laser beam to the rotational center of the two field derotators

The Southern Astrophysical Research (SOAR) 4.1m telescope, located in Cerro Pachon, Chile, has an active optics system that uses a Shack Hartmann wave front sensor to achieve optimal image correction and focus. This Calibration Wave Front Sensor (CWF

The SOAR telescope was designed to have a bare Aluminum coating. This coating is performed in the Gemini-South sputtering facility. Two coatings have been done on the SOAR mirror (2004 and 2009). On both occasions, the reflectivity obtained for the U

We describe the design and implementation of a fourth version of the TripleSpec near-infrared spectrograph (TSpec4). This version of the instrument was designed for and first implemented on the 4-m Blanco telescope on Cerro Tololo, and subsequently c

The 4.1-m SOAR telescope needs fast tip-tilt guiding and active correction of focus and astigmatism to reach good image quality allowed by the excellent site seeing. A concept of the new guider with a 2×2 wavefront sensor is presented. It uses the X
