Stub Mandrel Posted January 6, 2017 Share Posted January 6, 2017 Not sure where to post this but... With my SW 130P-DS I got several adaptors, including a number of adaptors for 2" and 1.25" eyepieces. I also got a tube, just over 2" (50mm) long. One end is clearly for a 2" eyepiece, with two knurled fixing screws, the other is internally threaded at about 49mm. I thought it might be to adapt a smaller 1.25" SW focuser to 2" EPs, but it's too big a thread, and it's too small to screw on the end of the 130P-DS focuser, which takes an externally threaded adaptor anyway (I got a spare one with the scope). My guess is it fits the 49mm external threaded focuser of some scope, somewhere, but which one? Any ideas what it might fit? Link to comment Share on other sites More sharing options...
