IC1396 widefield in H-Alpha


Recommended Posts

Widefield view of IC1396 and SH2-129 captured in H-Alpha with Astrodon 3nm Ha filter.  56x5m subs totalling 4h 40m.  Processed in PixInsight.  Calibrated with darks and flats, star aligned and stacked (Image Integration).  Post-processed using ABE (Automatic Background Extraction) to remove background gradient then stretched using HistogramTransformation (levels).  Finally the image was scaled for posting here.
