The Meade 16" LX200-ACF Advanced Coma-Free go-to telescope with UHTC multicoatings has research-grade optics on a go-to mount that's transportable (if not exactly portable), at a price within reach and reason. This Meade's coma-free field rivals that of the Ritchey-Chrétien optics used in many of the world's largest research telescopes.
