These included minor corrections to Figs. 1. 3 b) and 2. 8 and to the text of Fig. 5. 18. The most important change of all was probably the complete revision of the historical treatment of

ALTER

Major telescopes from Lord Rosse to about 1980,were able, in spite of the limitation of secondary spectrum, to compete with or even excel reflectors with apertures up to 1.22 m (Herschel) was a measure of the two great weaknesses of the reflectors of the time: the poor efficiency through low reflectivity and the problems of mechanical manipulation in such sizes.

Obloquy

Historical introduction,ny excellent accounts exist as chapters in more general works, in biographies or accounts of specific projects, but only a few books are devoted solely to the historical development. The works of King (1955) [1.1] and Riekher (1957, 1990) [1.2] are notable. The recent second edition of Riekher has b

Field correctors and focal reducers or extenders,the field aberrations of the mirror system. If the mirror system does not correct the axial image at the focus in question (e.g. the prime focus of an RC telescope), the field corrector will also be required to achieve this. Normally, field correctors are substantially afocal, i.e. they only have a
