Hadley Tube Ring Adapter for 6.25" Rings

Improved and larger version of the original Hadley Telescope ring adapter. The diameter has been expanded by 3mm to fit a 6.25" ring clamp, with added tool pass through holes to get to the mounting screws. The hardware used for this is the same as the original Hadley design, 10x24 x 0.5" screws. No supports required. Recommend 20% for a rigid part that will not compress when clamping.
