I have my Moticam camera attached to its lens and then a 3 pin connector to my 10x eye piece this then is going into the trinocular tube. I would like to replace this with a more stable set up which has the reduction optics as seen in the ebay advert. This would then free up my eye piece so I could use it for direct viewing. It would also get away from the 3 pin adapter which requires I screw in the pins to centre the camera eyepiece on the 10x microscope eyepiece, which does not feel ideal. The question is would this fit? Would it give a good image as now? Do I need to measure something to make sure? Is 0.5x the correct reduction? As you can see I have a swift 380 T. I am assuming I will need to use the c ring connector which came with the camera kit.
