Abstract
We present a survey of the results of photometric and spectral observations of a nebula AFGL 2688 in the system of post-AGB star V1610 Cyg. Apart from the analysis of the published results, our new spectral observations of the star at the BTA over 2002–2022 are also given consideration. A new understanding of the kinematics of gas and dust in the lobes of the nebula has been obtained. The totality of published data, registered in a wide range of wavelengths, allows us to consider AFGL 2688 as a prototype nebula for the stars undergoing the post-AGB stage. An assumption on the variation of the chemical composition of the central star is made. We discuss the prospects for studying the object in the optical range.
