Scorpius, Galactic Rift and Milky Way

Just love this area of the sky! - Camera collecting photons while drinking beer with some rocking music out the middle of howdy nowhere with me, myself and I. Illumination provided by the Milky Way is the best light source to navigating around site after night vision acquired. A long way from day to day life!
Probably the most action packed region of the sky, Mars and Saturn were welcome guests to the party.
Canon 6D (full spectrum), Astronomik clip in 'L' filter + some data using a 12nm Ha clip in filter, Zeiss Sonnar APO 135mm f/2.0, Astrotrac.
This is a multipanel mosaic consisting of about 100 panels. ISO3200, f2.5 with shutter speeds 4x3s, 4x8s, 4x30s and 8x90s for each panel aligned using PT Gui for each sub in a panel, then again to align panels for overall mosaic.
Combined using Fitswork to expand the dynamic range. Flat frames and dark frames applied to each sub beforehand using Photoshop. The remaining processing (gradient correction, levels, colour, etc) done in Photoshop.
