The Photron line of Ritchey-Cretien astrograph telescopes has been expanded wth the addition of four new truss tube models (10, 12, 14, and 16 inch). Designed for today's astro-imager, Photron truss tube RC telescopes deliver a sharp clear image from one edge to the other. The truss tube models are designed to carry on our long standing reputation for creating and manufacturing solid, stable, accurate tracking, mounts, in a high quality RC astrograph telescope.
Photron truss tube RC telescopes feature low thermal expansion quartz primary and secondary mirrors with highly reflective dielectric coatings maximizing the light getting to your eyepiece or imaging device. The RC optical design delivers coma, spherical and chromatic aberration free results; perfect for color and monochrome imaging. A fixed position primary mirror eliminates image shift that occurs when focusing other telescope designs. With a 1/12th wave or better primary mirror our RC scopes deliver images and views that are out of this world.
Each Photron truss tube instrument comes equipped with a dual speed linear bearing Crayford focuser that can facilitate our optional ASCOM compliant electronic focus control. Three extension rings are provided fora "flex-free" solid extension as a means to take up any unneeded back focus. Its backbone, made up of strong, light, carbon fiber truss supports hold the optics firmly in place while keeping weight to a minimum. Its open air design results in rapid cooling, reducing the "wait time" before use. Photron by iOptron, RC truss tube telescopes are sure to meet or exceed even the most discriminating imager or observer's expectations.
Photron Truss RC Telescopes come with: 2 speed Crayford style focuser, 2 inch to 1.25 inch accessory adapter, 2, 1 inch and 1, 2 inch focus extension rings, primary and secondary mirror covers, and a battery holder for the cooling fans.
The 16" model is special order only, and final shipping costs will be calculated upon purchase. For further information, please email email@example.com.
