Optical image (LRGB filters) of CB230 and surroundings. Approximate size 19.′5 × 13′. East is left, north is up. The bright patch below the centre with the veiled star BD+67 1300, is the reflection nebula Sh2-136/vdB 141. CB230 is the more opaque structure in the eastern part of the cloud, in which the cone of scattered light, associated with the outflow studied in this paper (Sect. 3.4), is clearly visible.
