Description

Took this on one of the first clear nights after the skies cleared from the Canadian fires (over MN skies).  

Guiding was not particularly great this night, hovering between 0.4 - 0.6 total rms (PHD2). Could be the balancing of my scope (I can never remember which is declination and which is azimuth, can someone reply with an explanation?)

My final image is pretty noisy; I also had particularly noticeable horizontal banding - perhaps need a longer exposure time. 

Stacking done in DSS. Combining and editing done in PSD. HOO palette with a combo HaOiii as a lum layer.
