About this image

Was hoping to collect RGB and H-alpha filtered data as well, but cloud came in and the wind increased bringing a premature end to the evening's imaging. So just luminance image, hoping to complete next time. Darks subtracted during imaging by SharpCap. Stacking and minor treatment in AffinityPhoto.
