What about this apo ?
When you bring a telephoto lens you can make an adapter with 32mm PVC plumbing tube socket and a rear lens cap a little scope below.
This is 53mm f/14 (a 70-300L with 2.5x Powermate) and with a 24mm Panoptic it works even handheld (31x).
During daylight viewing of tree branches it provides an almost color-free image and high contrast.
