If you have an Edge HD1100 0.7x reducer, have you noticed that the male threads are a bit larger than those on the rear of the scope? I recently took delivery of one and mounted it to the back of the scope just fine. However, when I put the adapter for my crayford feathertouch on the back, it's incredibly tight. It threads in maybe 3/4 turn and beyond that it's very tight. It mounts onto the end of the scope's threads near the flattener element just fine without any tightness. Any ideas on how to remedy this?
Thanks for your help
