Herbert,
There is of course another large refractor at Chabot that is not yet setup. It has an 18" achromatic lens using modern glass.
The old Swedish Solar Telescope.

My understanding is this will be useful for nighttime observations also. Nice feature of this scope is you can stay seated while the scope tracks with the two large flats. It will be interesting to compare the images with the two classic refractors.
