About this product

Model:  stellalyra_6_cf_rc

6" f/9 StellaLyra Ritchey-Chrétien with carbon-fibre tube. 

The RC optical design delivers images free of coma, spherical and chromatic aberrations, making it an excellent choice for colour or monochrome imaging of smaller galaxy and nebulae targets. 

A fixed position primary mirror eliminates image shift that often occurs when focusing some other telescope designs.

It also features a sturdy 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.

It is fitted with a Vixen-style dovetail mounting plate.
