Bresser Messier AR-102XS is a beautiful, bright tube with a lens diameter of 102 mm and a focal length of 406 mm, based on the doublet ED (low-dispersion glass). An additional advantage is the use of a hexagonal extractor, which has significantly lower deflections than the classic Crayford circular cross section. The tube comes complete with the AZ-5 assembly.
