About this image

Just bought the highly recommended Samyang 135mm lens.  Used at f/2.8 attached via adaptor (equipped with 1.25" filter holder) to my Atik 383L+ OSC camera and captured 10x300s exposures (@-20C) with ZWO narrowband (7nm) H-alpha filter and then repeated with TS optics uv & ir cut filter.  Used PHD2 to guide Orion Starshoot autoguide camera on 770/110 ED refractor all on SkyWatcher NEQ6 mount. Main camera was piggy-backed on the refractor.  Images calibrated (flats, bias, darks), stacked and processed using Astrophotography stacking feature in the amazing Affinity Photo software (one-off cost just 30 euros!).  Colours not entirely natural, but never mind!

Next photo is just the narrow band data.
