Most of the mechanical parts of our TI45 Astrograph are in phase of realization thanks to the hard work of various CNC machines. Great design, all 3D designed and FEM optimized, all CNC made, for the higher grade Astrograph in the market.
Indeed there was something missing! Now a beautiful inscription on the metal tells us what we are talking about. We are a bit ‘late, but here we come!
We do not call them “correctors”! They are simply the “lens groups” that are part of the optical design. So… “Triplet ED Lens Group”. They are for the TI 45 Astrograph in f/4 mode. Very soon we will show the f/8 mode “lens group”.
The first three f/4 correctors are ready. They are 126 mm of optical diameter (about 5″) and have three elements, one of wich is an ED lens.
This high-end design corrector is the core of our new optical design and thanks to this the optical performances are so awesome (see Optical Performances).
The primary and secondary mirrors are ready too, and autocollimation tests will start very soon. The f/8 correctors lenses are ready too and they are waiting to be mounted.
Here are the two blanks Schott Suprax 8488 ready for polishing. They are 456 mm in diameter (to have a useful diameter of 450 mm) and 50 mm thick. They will be processed with parabolic shape at f/3. These mirrors are made for the first two prototypes of TI 45 Astrographs.
