Thanks Ken.
The Quark off the Solar Scout has an internal barlow of 4.3.
The Solar Scout has an overall focal length of 930mm including the barlow and the reducer makes this around 465mm.
The 72ED has a focal length of 420mm x 4.3 of the Quark barlow, so it is running at 1806mm.
That means almost four times the focal length between the two set ups.
