The pier looks to me to be a standard Skywatcher EQ6 mount pier extension that in the photo has not been assembled correctly. The bit at the top should be in the bottom. See manual https://storage.googleapis.com/skywa...1455573215.pdf
Hi. As per my previous PM's I'm happy to take the T-adaptor, Variable Projection Camera Adapter and the reticle eyepiece. I can't use the other items though.
