Product description TS-Optics Full frame size corrector for Ritchey-Chrétien Astrographs The corrector was developed for all RC telescopes with f/8 which have a 2.5"+ focuser. It corrects the field without altering the focal length. The large clear aperture of 60 mm allows full illumination of full-frame size sensors with suitable adaption. Adaption to the focuser via the M68x1 thread The corrector has a male M68x1 thread at the telescope side. There are adaptions for many established focusers. For the adaption to the female M69x1 thread of the MONORAIL focusers of TS-Optics, AstroTec and GSO RC telescopes you need: M69a-M68a: adapter to the male M68x1 thread M68i-M68i: conversion adapter from male to female M68x1 thread Connection of the camera via the female M69x1 thread The corrector provides a generous working distance of 89.5 mm from the female M69x1 thread at the camera side. Connecting DSLR cameras For connecting DSLR and astro cameras via the M48x0.75 thread, the adapter TSO-M69A-M48A is used. You have exactly 55 mm from the M48 thread to the sensor position. That would be exactly a T-ring and a DSLR camera. Connecting the Zeiss style M68x1 adapters system Many astrophotographers like to work with this professional adapter system. The adapter TSO-M69a-M68a provides an M68x1 connection to the corrector. The working distance from the M68 thread to the sensor is 84.2 mm, so you have enough space for your adaption. Connection of the M48x0.75 adapter system Alongside the T2 system, the M48 adapter system is also very popular. Almost any off-axis guider and many filter wheels have the M48 connection at the telescope side or, at least, can be adapted to this thread. With the adapter TSO-M69-M48, you get a very short transition to M48 with only 1 mm length. Extension tubes for the female M69x1 thread For maintaining the optimal illumination, one should adapt to smaller threads as late as possible. For this purpose, 30 mm and 10 mm extension are offered. These are screwed directly into the camera side thread and reduce the remaining working distance correspondingly. Delivery contents Corrector
