462 mm QUARTZ Blank ready to be figured

Fused Silica (Quartz) performs an awesome thermal expansion coefficient of 5.4 x 10-7/ , 6 time less than borosilicate glasses, harder enough to allow better figuring process and advantage in terms of strength to density ratio.

TI 45 Telescope Control Software Test #01

First test of the Astrograph Control Software using a smartphone via WIFI. For more informations on our Astrographs, please visit our website: www.italiantelescopes.net The Control Software is full Ascom Alpaca compliant.


f/4 correctors

The first three TI45 astrograph f/4 correctors are ready!

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.


TI45 electronic board

All the electronic boards are under test and debugging

All the electronic boards of the TI45 Astrograph are under test and debugging

All the electronic boards of our new TI45 astrograph are now under test and debugging. They will control the 4″ field rotator, the four primary mirror cover shutters, all the sensors, fans, heaters on board, the power outputs, etc.
They will be integrated in the TI 45 Astrograph body.

TI 45 Astrograph Harmer Wynne: correctors being handled

Two executive projects of correctors for f/4 (Modified Harmer Wynne configuration) and f/8 (Corrected Cassegrain configuration) of our TI 45 Astrograph were frozen.

Optical performance is now arising  better improved. Results and charts as follows:
