M27 - a deep Dumb-bell

Recommended Posts

After several attempts with ever-longer exposures and an age trying to process the results, I finally managed to wring out some evidence of the faint outer shell of M27...

This was a combination of 300, 600 and 1200 second Ha/OIII exposures with my Esprit 100/Atik 460 combo, plus a bit of binned RGB for star colour. Details (if you are interested) here...

Outstanding work (looking for a zoomed in view) love the colours, neb and stars.

If you look closely you’ll see the graininess of the “wings” where I really pushed the curve.  I then had to batter down the bloated stars and smooth the result, though only over the masked bit.   The wings really are faint and I think it needs dark skies to do them proper justice.
