A mini LMC dwarf galaxy in Sagittarius

NGC 6822 or Barnards Galaxy, is a dwarf galaxy in Sagittarius about 1.6 million light years away and about 7000 light years in diameter. It has plenty of HII and a few OIII emission nebulae regions and to me it resembles a mini LMC. The galaxy sits in a pretty dusty region of the sky not far from the main band of the Milky Way, with lots of intervening galactic cirrus dust, which covers the field.

It was nice and clear for most of the two nights with little or no Moon and I enjoyed above average seeing when collecting the Ha and OIII but sadly, it fell well below average for the Lum and was pretty poor for the RGB ...so I did some tricky blending to use the NB data to boost the details a little but I used no decon or deliberate sharpening in the processing.
