In order to use the Meade 6.3 focal reducer, you will need that 2" chrome adapter. You could either try the one's off of your 2" eyepieces, or you could buy a brand new one from Scopestuff. The 6.3 focal reducer will screw into the True Technologies filter wheel, but the threads are too long and it will hit the filters and prevent the filter wheel from turning. So I had to use a spacer. I used a 55mm to 52mm reducer as a spacer. Those should be available from your local camera store or B&H Photo.
