M42 HDR 54 stacked subs 2H10min
Lens: Pentax 150-450 + x1.4 TC Camera: K1 Photo Location: Sydney Shutter Speed: Above 6s Aperture: F10

My previous attempt at this was using astrotracer and as such limited to just 8-10 seconds per sub frame.
I now have a motorised EQ mount (Skywatcher EQ6R) so this was a HDR of
ISO 400 @ 120 seconds x 9
ISO 800 @ 120 seconds x 30
ISO 800 @ 180 seconds x 10
ISO 6400 @ 300 seconds x 5

The iso400 was to tame the highlights in the core and the iso6400 was to grab more of the faint cloud around the edge.
This is really the only DSO I can image from my home. But I am out into darker skies tonight to have a go at some fainter nebula.
