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!
Very nice. The Blue Horsehead Nebula is one of my all time favourite reflection nebulas, and you've done it justice! I cannot wait till we get good enough weather here to give this another go this year.
Beautiful image indeed! When I upgrade my main imaging camera, I'll be using my IMX294 camera on the back of a 135~180mm camera lens to get a wider view... I'm really looking forward to that!!
