Description: Comet-centaur 29P/Schwassmann–Wachmann 1 was observed in CO+ emission and continuum during 2007–2009 using the 6-m telescope SAO RAS. The distributions of dust and CO+ ions in the coma are not similar and vary depending on the level of comet activity. CO+ ions are more concentrated towards the nucleus than the dust continuum. The column density of the CO+ was derived and the production rate of CO+ was estimated. We showed that impact ionization by solar wind particles is the main ionization mechanism at large heliocentric distances (more 5 au).
