NGC1499 – The California Nebula

NGC1499 – The California Nebula

with No Comments

NGC1499 is a huge nebula resembling the state of California (hence the name).   At roughly 2.5 degrees wide, a full moon could fit about 4 times across in this image — quite large indeed!  In natural light, the nebula is red, but this image is a narrowband 2 frame mosaic (stitched together).  Taken with ta Tak FSQ 106 and QSI683 and 3nm Astrodon filters.  Approximately 30 hours total integration time, about half in Ha, and 8 hours each of SII and OIII.

A few galaxies are visible in the bottom right — if it weren’t for the annotation (done in PixInsight), it would be easy to miss them:
