At a local auction I obtained an American Optics A10, Infinity plan apochromatic objectives X4; X10; X20; X40 & X100 (oil). Eyepieces are WF X10, but it is designed for demonstrations with a DualView attachment so that tow people can look through it together. There is also a light green arrow for use in indicating points of interest.
It should come in handy for demonstrating at Gormanston!
