Lucky to have been in Florence for a week and to have visited the Galileo Museum.  Lots of interesting 600 year old astro kit and Galileo's index finger bone in an egg shaped glass jar .  Like to think the good old boy has been giving the 'Inquisition' the finger for six centuries! :happy7:

Blimey, those scopes look about f30 at least. 

I reckon you are right,  his scopes were stopped down to about 25mm and they were about 930mm long- so assuming f=900mm- F36 ish?  Must have had a very small FOV and not much light getting through to the old boy's eyeball.  He did pretty well to see Jupiter let alone its Moons and no wonder he struggled with Saturn's rings. :icon_biggrin:
