About this product

Model:  stellalyra_8_cf_rc
Part Number:  RC8-Carbon

8" f/8 StellaLyra Ritchey-Chrétien with Carbon Fibre Tube

An excellent choice for imaging smaller galaxies 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 often occurs when focusing some other telescope designs.

It also features a sturdy dual-speed 2" Crayford-style linear bearing 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 Losmandy-style dovetail mounting plate on the base and a handy Vixen-style dovetail mounting plate on top for piggybacking accessories.

The Carbon Fibre telescope tube offers low thermal expansion,  high strength, lower weight and a gorgeous fit and finish.
