About half an hour ago I finished doing my first pass of processing on all 100 images (10x10 panel mosaic at the moment).

This is a quick stitch of a 3x3 and a crop of the resolution.

I am using a Nikon D700 and my 130mm F/5 refractor so it is effectively a 670mm F/5.1 lens (plate solved). For this one I have only been able to use 60s exposures at ISO1600 (took all of them last Saturday night, due to Sagittarius setting I couldn't go longer). I REALLY need 120s especially for some of the lower signal areas as there is too much noise. Unless I can swamp the camera read noise there is some low electrical noise that cannot be processed out.

Next year I'd like to attempt a 15x15 using a Nikon D810a and collect 80-100 hours of data
