I know this is late but i have made an 3D printed adapter to make these two fit here is a link for anyone who may want it it is held to the 61 by two M4 x 10 screws you may need to file these a little to stop them hitting the focus tube You will need a square M3 nut and a M3 x 10 screw to clamp the guide scope to the adapter. https://www.thingiverse.com/thing:4140009 all the best Bob
