Never say final, right!?!? Grabbed some RGB in between clouds, rain, etc to add to my HA that I had posted earlier. It has gone through a number of iterations but I'm pretty happy at this point. Not that I might not revisit it again! :grin:

I'd be happy too with this. There are so many version you can have of M42! Post 'em if you got 'em!

Beautiful work Warren! Is M42 ever really done? :) I spent hours and hours on it a couple years ago, and I'd like to do it again, next season...

I really love it when you can see the faint dust around this area as well as the trapezium at the same time. Fantastically done!

Regards,
David

That's well done, Warren, with a judicious, natural processing.

Looks great Warren...very tidy blending to the core.

Thanks Steve! Glad I was able to get something done this month, it does not look promising for a while!

Thanks Mike! There are so many ways to process this object I decided on a minimalist approach this time.

Looking nice - I want to do a good one of M42 too.
Would 5 hours of data be enough?

Thanks! It will depend upon your skies, if you have dark skies 5 hours would work well. If you are doing mono then put most of the time into Luminance (HA in my case) so you get the details you want. Half of my total time was done focusing on the HA which I used as the Luminance channel.

Thanks Tom, Bill and JP!

JP, have you done one of your 3D images of M42?

Nice! I really like how you maintained the core and still went deep with it.

Thanks John! Lots of different exposures and layer masks! I really want to try a close up of the Trapezium sometime.

What about gathering Luminance but with my light pollution filter?

It's a 2" CLS-CCD from Astronomic.

If you are using an LP filter then you will need longer exposures to get the deep stuff but the filter should allow that. My suggestion would be to first grab your short exposures in each channel for the core. I do 10 seconds and that is pretty good to keep the core from blowing out and it doesn't take long to get 30 subs for each channel. Then try 2 minutes for the inner portions of the nebula and then finally go as long as you can without saturating the image with sky glow. 5 minutes was good for me and I am highly light polluted, but I was using an HA filter and the light pollution has little effect on it. If you can see the faint nebulosity at the top of the nebula in your sub at 5 minutes you should be good, but you will need at least 2 hours in my experience to get a clean background. Your chrominance you can typically get away with less and I blur mine so that no noise comes through the Luminance layer when I blend them together.

Hope this helps!
