IC 4592
IC 4592 is a large blue reflection nebula lit by the light from the multiple star system ν Scorpii - the brightest star in the frame, just below center.
This photo is another framing failure - the nebula is commonly known as the Blue Horsehead but I have truncated the horse's muzzle (at bottom right). It needs a wider field of view, or a mosaic - I'll maybe try again next year.
Anyway, this image is an integration of 211 x240s subframes captured on a QHY168C OSC with WO Zenithstar 103 scope. An STC multispectra LP filter was used. Imaging was controlled via SGP and PHD2, all post-processing was with PixInsight.
Observed from Prachinburi, Thailand
