Zuiko 50mm on Atik460 Ha Sadr region

[physicus]

First light for this little 50mm f1.4, set to f5.6, and my first real foray into widefield really.  Three hours total (5x1800s + 3x600s).  AZEQ6 mount, guided with an Altair 60mm.  Really impressed with how this turned out; the limitation is the camera resolution for a change, rather than the optics /seeing etc.  The exposure at f5.6 was actually accidental - I thought I was fully open at the time !  I wrapped a small heater strip around the lens, and found I could focus no problem by twisting the ring through the heater.  Capture and focus in Nebulosity.  Of course, now I want some OIII, but tonight's probably not the best chance - with the moon an' all.  Good chance to test the lens fully open in Ha though.  I've not processed this beyond a stretch, so you can see what is really happening.

That is a brilliant wide field result. Who needs an astrograph?
