The Starhopper requires serious modification to fit a 2" focuser using the existing hardware. The secondary mirror cell is supported by a single vane spider that anchors to the 1.25" focuser by the same screw that holds the focuser in place on the tube. The focuser can be removed and the spider reanchored with a lockwasher and a nut. But a new hole would have to be drilled through the tube to accommodate the 2" focuser. To accomplish that and retain a comfortable viewing position, you would have to fit the focuser on the other side of the tube. The secondary cell can be rotated in the spider hub to access the new position. Then you have to fill the old focuser hole. Sorry Doug, thought of this after you left yesterday, but it is a major reconstruction.
