My C11 come with bottom Losmandy-D compatible dovetail but no dovetail nor any handle on top. With a little help of a friendly soul from US who has shipped to me C11 radius blocks and matching ANSI bolts, I managed to install 3x2cm aluminum rail on top - perfect for handling the scope in cold and when the OTA is dipping with dew. The longest task in this project were few weeks it took the parcel with radius blocks to reach Poland.
