First,the mirror was cut, polished and parabolised by amateur astronomer Attila Csillag of Arad, in a series of three identical mirrors.Parabolisation of the first mirror went very well, is powering since then Attila's RFT reflector.
On the second mirror the parabola resulted zoned ,the zone from 0,7R outward being in a parabolic surface with a slightly different focal length.
This become my RFT mirror.
Correction of the defect was made by the Hungarian optician Csatlos Geza who resumed the process from the grinding with the finest abrasive.
In the picture ,one can see the signature of Csatlos Geza ,reflected by the Aluminium coating.
|Am montat intai oglinda intr-o montura azimutala in furca cu un singur brat si pe care o avea Attila disponibila.|
Initially , I mounted the mirror in an azimuthal single fork arm mount that Attila had available.
