First lights of NOU-T at South Rouen Observatory

After a Lhires III equiped in low resolution mode with a 150 l/mm gratings (2009), LISA (20120), eShel (2015), my observatory is now equiped with a NOU-T built by my friend Joan Garro.

The NOU-T is based on the optical concept designed by Tim Lester.

From my point of view, based on spectra received for the ARAS database, Tim's concept (and treatment) gives the best results in amateur echelle spectra.

See, from Tim's spectrosgraph to NOU-T

NOU-T is placed directly at the focus of the telescope, which avoid the usage of a fiber and the associated loss of light..

This page describes the first lights of my NOU-T, kindly built and tuned by Joan.
