The Riccardi Large Astrograph, RiLA, is the first of this kind due to the review of italian optical designer Massimo Riccardi. This nowdays, new optical design comes from a modification of the Harmer-Wynne scheme. The system is made by an aspherical primary mirror, aspherical secondary mirror and a lens group in the back. The RiLA is corrected in the visible-near IR range, with more than 80% of energy focused in 4-6 microns RMS spot! Like the Riccardi Honders scheme, the telescope results very compact and light weight. The main goal of the RiLA is to cover a very wide corrected field with a fast focal ratio.
