This is the start of a deep mosaic of the LMC. It is part of the previous colour mosaic enhanced with HA and O3 narrow band.

Canon 300mm F2.8L ,at f/2.8 with 5DH, Astronimik HA and O3, 5x(1,2,4,8 min) 10x16 min, at 800 ISO with fridge at -10C. Because the darks match the lights so well as they are taken at the same temperature (within 0.3 C )the noise is almost non existant even at 800ISO.
I still have to get the colour looking 'better' but this will do for now.
