Description

This is a deep image taken with Astrodon 3nm Ha filter. The conditions for two of the three nights this was imaged over were very poor with full Moon and an average SQM-L of 18.0, while the best night was 18.8 and no Moon. Most of the images were taken on the poor nights. This just goes to show how valuable narrow band filters are for those with poor skies.

So going deep on this means it looks very different to most images of this nebula and appears much larger.

All processing in PixInsight and final touches in Photoshop.
