NGC 6188 and NGC 6164

Game of Thrones returns for its final season and winter really is coming... Apparently...

So it is only fitting that I take a look at NGC 6188, which is sometimes described as the Fighting Dragons of Ara. At middle bottom is NGC 6164, a small planetary nebula, which some like to think is a dragon egg. An absolutely beautiful part of the sky.



20 x 600s ISO 1600 (modded 1200D with 12nm Ha filter)
24 darks
32 flats
superbias of 100 frames
WO Star 71 and HEQ5 Pro



The mount guided at less than 1 arc second RMS all night and I pushed dithering to moderate every frame.
