Erhard Hännsgens 1.07 Meter f/4.5 Dobson at ITV 2003
Pictures: Rolf Stadelmaier and Volker Gerhardt
This is Joshua, the sun of Michael Koch in front of the 350 kg mammoth.
Compare the sizes: Rafael's 30" (background) used to be the biggest scope for many years at ITV, but looks really compact against this 42" Leviathan. The M51 spirals made me nearly fall of the ladder. (picture taken from Daniel Marquardt)
Yes, this is really big...
