A quick shot of the Orion Nebula (M42), one of my favourite celestial objects and a really satisfying target. I've been waiting a year for an opportunity to image this nebula again, this time with a polar alignment and guiding to enable much longer exposures than the 15 second subs I took last time and with a lower ISO to reduce noise. 13 x 4 minute exposures at 400 ISO 8 x dark frames 10 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Total exposure time - 52 minutes Guided with PHD Processed in Nebulosity and Photoshop
