244 mm PLUS support rings (PrimaLuceLab, SKU: PLLANSU244P ) are a pair of massive rings designed for tubes with a diameter of about 244 mm - typically for 10" - 11" SCT or 12" Newtonian/RC class telescopes. The design, in accordance with the PLUS mechanics standard, allows for mounting Losmandy/Vixen rails under the tube and guider guides or other accessories above the telescope, maintaining perfect axiality.
