Thank you, Steven, for an interesting image of NGC 6822.
According to Sidney van den Bergh in his encyclopedic book "The Galaxies of the Local Group" (Cambridge University Press), N6822 is over two mags less luminous than the LMC. (measured in the V-band)
Yet it still looks complex and interesting, as we are very fortunate to be located in the same galaxy group.
NGC 6822 is a more typical dwarf irregular galaxy than the LMC, in that it is low surface brightness and its overall rate of star formation is very low.
Barnard's Galaxy is not particularly blue either, in the optical regime, with an optical color of B-V equals 0.79
(the LMC is much more blue, at B-V = 0.52)
Some impressive Large Telescope images of N6822 and other members of the Local Group can be found at the website of the Local Group Survey:

One of the more interesting multi-wavelength observations of NGC 6822 concerns the relationship of the optical image to the vast and distended cloud of HI (neutral atomic hydrogen) in which the galaxy is embedded:
Here is an image which overlays DSS (optical) with the borders of this disk of cold atomic gas:
The gaseous part of N6822 is a completely different shape and size compared to the optical part! Also, the vast gaseous disk has only formed stars in its very central part......
cheers,
the bad galaxy man
