Abstract

This paper discusses the features of objectives intended for amateur and professional astronomical observations. Type-OK4 crown glass with special dispersion behavior is used to achieve apochromatic correction in refracting objectives, since the technology for obtaining high-quality blanks made from this glass makes it possible to create apochromatic objectives with an entrance-pupil diameter of up to 304 mm. Experimental compositions of the glass have been developed that make it possible to obtain apochromatic systems composed of two lenses.
