I wanted to bring out some of the dust and gas clouds around the bright nebulae in Orion - so I’ve processed this to highlight the background.

I was going to give M42 a miss this year but I couldn't resist having another go at this spectacular nebula. Imaged over 2 nights, it is a stack of 194 x 180s frames and an HDR composite with a stack of 74 x 60s frames to recover the separation of the stars in the Trapezium at the centre of the nebula.
Captured on a QHY168C camera behind a WO ZS103 refractor with Flat6Aii and an STC astro multispectra filter. The mount was a Skywatcher EQ6R Pro and the imaging sessions were managed with SGP and PHD2. All post-processing was carried out in PixInsight
Taken from Prachinburi, Thailand

This little springtail also wanted a bit of attention...
