Blue Horseyhead Nebula - IC 4592
Shot this with Rokinon 135mm @ F2.8 attached to an ZWO 533MC pro. All mounted atop an Ioptron SGP with guiding too. 5h 42m of 3 min subs. All taken from my backyard in Dunedin in bortle 4/5 skies. Processed in PixInsight and polished a little using RawTherapee. I reckon the Rokinon lens produces such impressive, sharp images!
