Massimo are very close to this project and its development.
how do you think to realize the secondary?I think you should realize
a machine x small optical surfaces nothing in particular
a gearmotor x turn 10giri per minute a bushing x fix the diskette
It remains amazed by observing the degree of fineness and mechanical realization of professional telescopes of sig.Massimo Boetto.
But we can also create a mechanically that Cassengrain “functions”?
It absolutely In Jean Texereau:telescopes of the kind cassengrain,in chapter
on the mechanical part it is explained in detail in the final realization phase,it is curious to observe
the leap to today's materials and mechanical techniques that when the book was written not exist, with less noble materials but respecting a greater mechanical fineness compared to a”simple” newton,you should have no problems. If you managed to achieve this amazing mirror I do not see what can stop you! always polite and comprehensive I thank you for the answers they will treasure
I will keep you informed
ciao Now some advice:I've never worked diameters from 400mm x and giving good he can to buy
the blank in question which is the best strategy to follow?best work 2 glasses equal
or use a sub diameter?
thank you ok I try in industrial glassworks,I'm in Milan south.
thanks to Massimo proposal I keep it for good if I do not solve.
I asked various optical who engage in various capacities in the construction
of goals and I'll know the results,there would Reginato but the diameters up to 300mm
I am currently not as disponibili.così 200 or 250-
the second asked me a 400mm x 40mm thick Pyrex € 1100
euro 400 sodium calcium.
disco da 330 calciosodio in thickness 30mm € 330
it would be my intention to make a kirkham by 350mm by 20mm but I'm afraid
thick are few
