MuSCAT3: a 4-color simultaneous camera for the 2m Faulkes Telescope North

摘要

We report the development of MuSCAT3, a four channel simultaneous imagcr installed on the 2m Faulkes Telescope North at Haleakala Observatory on Maui, Hawai'i. MuSCAT3 has a capability of 4-color simultaneous imaging in g (400 550 nm), r (550 700 nm), i (700 820 nm), and z_s (820 920 nm) bands with four independent 2048x2048 pixel CCDs. each having a field of view of 9.1x9.1 arcmin2 with a pixel scale of 0.27 arcsec per pixel. The development of MuSCAT3 started from September 2019, and MuSCAT3 achieved its first light on September 28th, 2020. The Las Cumbres Observatory started science operations of MuSCAT3 since November 4th, 2020, although a part of its capabilities are still limited.
