Description

Orion Nebula in straight-up LRGB, no Hɑ enhancement or anything.

I'm collecting other data for a narrowband M42, at some point I might end up doing some enhanced versions or something, don't really know what I'll end up doing there eventually.  This doesn't have as much contrast as my M42 from last year, but that's mainly because I cheated and boosted the luminosity layer with SHO data for that; this is closer to what it would look like in straight-up true color.

Didn't do any crazy HDR stuff with this; generally that feels too artificial to me, I'd rather have bright parts bright and not utterly crush the higher parts of the dynamic range; that really looks flat to me and kind of strange.  I'm just not (currently) willing to go there.  It's not like you can't still see the Trapezium.  OTOH, I can't get more than a hint of the dim detail here, either, no matter how I curve the image; the data just isn't there.  I'd probably need either darker skies or more time on the target or something to get that.  I dunno, I guess other people generally do better versions of this than me, or at least different ones.  I'm basically happy with what I've got, though.

It was a real struggle getting this (or any other) data recently.  Conditions have been pretty poor, and almost half of the frames I've captured have been lost to clouds or...  Bad seeing?  Extremely bloated stars at times lately, randomly from frame to frame (it wasn't wind, although wind has often been an issue at other times, too) after the snow and extreme cold we've been having lately (cold enough that I'd have to heat the camera to match my darks).  And that's just on the nights I've bothered shooting.  Overall, getting ~10% of the possible hours of full dark this month (something I'd expect more in spring than now), and (more annoyingly) it's hard to decide exactly what threshold is useable and what's not; very little of the data is pristine.  Par for the course, I guess.

Also got really bad reflection artifacts on this target which I had to clean up.  I've seen those on other targets, but nothing remotely as bad as on this one.
