Modified Canon 450D, Sigma 120-300 at 300mm f/2.8, Astronomik CLS-CCD. Main 42x2m subs. Core 24x30s subs. Heavy lifting by PixInsight, merge and finishing by PSE.

This is the deepest I've managed to image this yet, and I've tried to process it to prioritise the subtle dust structures at the possible cost of a rather muted brighter regions. And the core was still a pain even with two exposures... any further tweaks and it goes again! I know there's a lot I could try to tweak further but I've been staring at the monitor too long already this morning...

Is it me or does the dust under the running man look like a rabbit?

Hi folks,

I captured way less than half of the intended number of M42 photons this winter and as it is now unavailable to me for the rest of the season I thought I'd wield the astro-spanners and see what I had:

    Image

      M42 - The Orion Nebula

5 x 40 seconds in each of red, green and blue and 6 x 200 seconds in each of red, green and blue. I managed just 6 x 1,000 seconds of red subs and 2 x 1,000 seconds of blue subs and without any green that wasn't a lot of use for this object. And narrowband never happened - what a winter! Captured via my TEC 140 (f/7) and my FLI ML16803. The 100% version is available here for pixel-peeping fun.

Bob.

This is my first attempt at getting M42, it was a bit of an afterthought after shooting Pan-Starrs for an hour or so.

Here's a 15 second exposure, ISO 1600, f4, 300mm, cropped and enhanced in LR.

Great capture Bob, looks really detailed, good job :)
EvanK, I really don't know much about this kind of stuff, but from other work I've seen, it looks pretty nice to be your first attempt

This is a composite of very old Hyperstar I data together with DSS2 data. As the DSS2 data is only a single (long) sub in the red and blue channels - it is very noisy. Something like 100 short subs from the Hyperstar I nicely smooths out the DSS2 data.
