I have this Unitron Super focuser (unbranded - likely missing stickers, so likely late production). But I seem to be missing either the point or some part(s). I got it because I "need" to do astrophotography with a dslr which seemed too heavy for the standard focuser on my Polarex model 131 telescope. I have the correct adaptor for fitting this, much larger focuser, to the OTA (although it won't fit the original box).
However I seem to miss what goes in the eyepiece end of the smallest tube. And also some sort of clamping collar to the drawtube (the big one has a lock but not the small one). What am I missing?
Also, what would I do in order to fit 2" stuff to this focuser?
Hope somebody knows something of relevance or has ideas!
