About this product

Model:  stellalyra_6_rc

Incredible value 6" f/9 StellaLyra Ritchey-Chrétien

An excellent choice for imaging smaller galaxy and nebulae targets. 

The RC optical design delivers images free of coma, spherical and chromatic aberrations so is an excellent choice for colour or monochrome imaging.

A fixed position primary mirror eliminates image shift that normally occurs when focusing some other telescope designs. It also features a 2" dual-speed rotatable Crayford focuser.

Three CNC-machined spacer rings are included that provide flex-free focus extension when required.

Interior knife edge baffles reduce stray light for maximum contrast.

Fitted with a Vixen-style dovetail mounting plate.
