Ukita Homepage; Initiatives for Metal Mirror Telescopes (iMMT)


Experiments of a metal mirror telescope dedicated to spectroscopy;
A mirror with a Hartmann constant of 1 - 1.5 arcseconds should suffice to carry out observations
from the ground under seeing effects of a few arcseconds.

Concept:
+ --> 2012/Aug/18 --> 2014/Oct
We use a telescope mount of the 65-cm solar telescope (1967 to 2002) and high precision aluminium panel technology (ASTE, ref1).
