At first there wasn't much visible but after few minutes some details came in view. IC 434 is pretty hard and faint object. The weather wasn't ideal but still I was able to see Horse Head with H-beta filter. It is pretty clear darker area in IC 434. The east side is very sharp when other contours are much fainter. Three brighter areas in IC 434. The shape is very difficult, nothing like in photos. H-beta makes stars ~3 mag fainter.
