Mystery resolved! Leo is looking at NGC2903 barred spiral galaxy 🙂 Galaxy is about 30 mln light years away and is quite nice object for astrophotography. Unfortunately weather this night was not quite good – seeing got worse and also some high clouds appeared, so the photo has not as many details as I would like it to have… Anyway another LRGB picture approach, 150:40:40:40 minutes of exposure, binned 1:2:2:2.
