About this product

Model:  stellalyra_10_rc

Incredible value 10" f/8 M-LRS Ritchey-Chrétien

Perfect 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 often occurs when focusing some other telescope designs.

It also features a sturdy dual-speed 3.25" 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 Losmandy-style dovetail mounting plate on top for piggy-backing over accessories.

The iOptron CEM120 mount pictured is not included smiley
