A very dimmed but vast diffused nebula on the border of Cassiopeia and Cameropardalis is Sh2-202. The nebula has been positioned just east of IC1848 with a span of 80 arc minutes or so. You can see an indistinct dark lane crossing in center of the nebula, and a sparse open cluster of Stock23 with 25 member stars has been piled up.
