About this product

Model:  iop_rc8_6112
Part Number:  6112

Incredible value 6" f/9 iOptron Photron Ritchey-Chrétien

An excellent choice for imaging smaller galaxy and nebulae targets. 

IOptron Photron Ritchey-Chrétien telescopes feature low thermal expansion quartz primary and secondary mirrors with 99% percent reflective dielectric coatings.

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.
