The Cassini C-80EFSSF optical tube assembly features an 800mm focal length. The Primary mirror is a 80mm heavy duty mirror cell with push / pull collimation screws. The primary mirror is aluminized with Silicon Monoxide Quartz overcoat providing 92percent reflectivity and a resolving power of 1.4 arc seconds. The secondary mirror has an obstruction of approximately 25percent linear (approximately 6percent of the total area). The optical tube assembly is diffraction limited at ?4 (1/4 wave in Sodium light). The finderscope is Cassini's Mars' Eye electronic Finderscope which helps by getting the observer behind the telescope without losing the surrounding field of view when targeting objects.
