Amazing field at 47x and UHC-filter. The Orion Nebula was 50 above the horizon and that affects a lot. The trapezium zone was very bright, there are some darker areas visible such Sinus Gentlii and Sinus Magnus. The eastern wisp is brighter and better defined than western. It's also much sharper. There were a lot of faint nebulae on the west side of the main-nebula, also some brighter areas were visible with averted vision. M43 is quite small droplet on north-side.
