Looks good Barry! Shame about the viewing angles.
Both Baader and Blue Fireball Technologies sell a female to female T thread adaptor that would fit the Orion FF, so an eyepiece adaptor, also Blue Fireball, with T threads on one end and compression spring on the other would mean eyepieces/diagonals will fit without duct tape
Agena Astro in the US have all the bits needed. I'm going to try an Orion FF on my f7 frac soon.
Like to know how the 120 is going Barry.
