Description

This is my first earnest attempt at narrowband SHO imaging.  It is also my first Hubble pallet image.  I did not look up what the conventional weightings were for Hubble pallet images, so I winged it and went with what I thought looked good.  The image was captured over two nights.  32 exposures of 5 minutes each through each filter (Chroma 3nm Ha, OIII, and SII).  I chose M16 to be my first target because of its relatively strong SII emission.  Russ Croman's StarXTerminator was used to reduce the stars.  NoiseXTerminator was also used to ease the grainyness.  Topaz SharpenAI was used with a light touch enhance the detail.
