Hi all: I bit the bullet and drilled 4 small holes in the new SW880 tube and made an adapter plate to fit my Crayford 2" 1-1/10-1 focuser which has 70mm hole spacing as opposed to the 85mm of the R&P. Operation went well and the 70mm spaced holes fitting just inside the hole in the tube. I also mounted my 9x50mm finderscope, which I modified the eye piece to take the Canon right angled viewer, which, has the advantage of a 2x feature and focusing ring.
I guess I will fit the R&P on the old 8" and offer that for sale in the new year sometime.
I reckon that also voids my warranty
ah well .....
Here"s a pickie of the two items.
