M101 Pinwheel Galaxy ( Jonathan Anderson) 4″ f10 achro on HEQ5 Pro Canon 700d (umod) @ISO 1600 120x40sec + darks,flats etc. Processed DSS & GIMP Gradients below the galaxy show how this has been stretched to the limit. Less stretch leaves the spirals disappointing. As Pat said recently – this target could do with more time.
