Comet 67P/Churyumov-Gerasimenko (67P) was imaged with the 2m telescope at Mt.Wendelstein Observatory in the Alps. Coma and tail monitoring was performedduring 51 nights between 22 August 2015 and 9 May 2016. The images through rand i Sloan Digital Sky Survey (SDSS) filters show the dust distribution aroundthe comet, while images in the SDSS g filter indicate also the presence of comagas in early September 2015. The dust color of 67P implies intrinsic reddeningof 9 %/100nm. After maximum shortly after perihelion passage the dust activitydecreased with a heliocentric exponent of 4.1 to 4.2 from late September 2015until May 2016. The opposition surge during early 2016 can be explained by alinear light scattering phase function (beta ~ 0.04) or an asteroid-likeHG-type phase function (G ~ 0.15). The radial brightness profile indicates a'quasi-steady-state' dust coma from late September to the end of 2015. Dustfragmentation during about a month after perihelion may be responsible forradial coma profiles with slopes below unity, while dust accumulation due tovery slow dust expansion velocity may result in steeper than unity profilesduring 2016. Three fan-shape dust structures are characterized in the coma of67P. A short dust ejection event on 22 -23 August 2015 has produced a dustarc-let and jet feature in the coma. In September 2015 the appearance ofcometary dust tail is dominated by young dust produced around perihelion. Theolder dust dominates the tail appearance as of mid November 2015.
