There is a good dust cover over the main mirror, and I cover up the part with the secondary to minimise dust. There are some large rubber buffers that could be removed to stop the gap, but we have not bothered. The rotation is excellent, just like butter, much better than the 8 inch dob we have that has telflon, this has a metal roller device. Has very large secondary, but all in all very pleased with it. As it collapses it is transportable and can even fit in our small motorhome. The crayford is pretty average, but it works.
