Rigel TMB Planetary UWA eyepieces are some of the most respected eyepieces available. They provide exceptionally high power along with very comfortable eye relief making them one of the best eyepieces around. 6 elements and 58 degrees field of view coupled with 14mm eye relief. They are noted for their high contrast and definition because of their high light transmission and minimal light scatter. The eyepiece is brilliant for lunar and planetary work but is also a very capable performer at splitting double stars and showing huge detail in objects such as nebulae and globular clusters.
