iOptron Photron 250 RC f/8 CEM60 Telescope Package
The Photron 250 Package by iOptron is a 250 mm (10-inch) Ritchey Chretien astrograph telescope, an OTA, mount, and tripod which were designed for today's astroimager for a complete imaging and visual system.
Introducing Photron, Ritchey Chretien (RC) telescope system by iOptron: Photron instruments are built to facilitate today's astroimager in capturing the data necessary to create spectacular edge to edge sharp astroimages. To achieve this goal, The RC telescopes incorporate low-thermal expansion quartz primary and secondary mirrors with 99-percent reflective dielectric coatings. The RC optical design delivers coma, spherical , and chromatic aberration-free results; perfect for color and monochrome imaging. A fixed position primary mirror eliminates the image shift that occurs when focusing some telescope designs. The steel tube interior is equipped with 10 knife edge baffles to diminish contrast-reducing stray light from bouncing and improving the instrument for both visual and imaging uses.
There are three extension rings provided for a flex-free solid extension as a means to take-up any unneeded back focus.
Mounting Plates: The 250 mm model includes both top and bottom Losmandy-style dovetail plates adding rigidity to the tube while providing attachment points for the mount and other accessories. The 200 mm model includes 1 Losmandy-style and 1 Vixen-style mounting plates. The 150 mm model includes 1 Vixen-style mounting plate.
The smooth dual-speed 2-inch linear bearing Crawford focuser comes complete with an ASCOM compliant electronic focus control, delivering disturbance-free focusing.This Photron 250 system is packaged with an iOptron patented CEM60 Central-Balanced Equatorial mount, a sturdy iOptron tri-pier, and an iOptron ASCOM compliant electric focuser for disturbance free operation.
