image shows the rosette nebula, an HII region that has shells of red gas in circular layers that resemble a rosette around the outside with little nebulosity in the centre. Some people think the shape resembles a human skull. There is a bright star cluster almost in the centre and the whole nebula is surrounded by a black sky and numerous faint stars

#VeilNebula complex, taken from Oxfordshire, UK. 70mm refractor, 0.8x focal reducer, #AltairQuadband filter + astro-modded #Canon1100D. Shot during summer, 45x120sec ISO-1600. I removed the stars before processing & merged back in at the end, but I need far more practice at that!
