Incredible value 6" f/9 iOptron Photon Ritchey-Chrétien
An excellent choice for imaging smaller galaxy and nebulae targets.
IOptron Photon 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.
