M42: dust vs. core :question:
Hmmm, I sacrificed the core .. ;)

Beautiful image Ian. Sooooo much dust. Love it. What equipment did you use and information on sub lengths and camera please. Great shot.

Nicely done Ian. Just goes to show that there is always something new to do even in the most photographed objects.

Most impresssive.

We tend to think in terms of "objects", but your photo shows it's really all one great big interconnected galactic disc.

Very skillful.

Best,

Can't you do some HDR trickery and show both?

I wish I could, but even @ iso100 all raw images have the core overexposed :(

Can't you just take one or two shorter exposures at ISO 100 that don't saturate the core and then combine the images? I trust you know how HDR works...? If you don't, read up on it. HDR = High Dynamic Range. Sometimes HDRI with I for Imaging. ;)

Nice dust, Ian, and you've respected the light!

Very nice! :thumbsup: Brought out the fainter areas nicely! Clipping the highlights is only a small sacrifice for brining the fainter nebulosity out. If you have unclipped data, a mild HDR (just enough to round of the highlights) might serve well. One of the better wider field M42s I have seen in a while. Love it! :)
