Orion Nebula in HaRGB

This hustling and bustling neighbourhood 1,400 light years distant is brimming with towering pillars of gas and dust that are home to fledgling stars.

Shot over two nights this week from my home in Bortle 6 NW England.

That’s a lovely image of m42, and from a fellow Quattro 10 user that’s nice to see, you pulled some nice detail in the clouds

Thanks Craig, it’s occasionally a pain to use but when all works, it’s a great scope!

It's a nice image, I need to give this target more attention but keep getting distracted

Wouldn't normally re-post but have re-processed this image paying much more attention preservation of the core. Here is the updated version!

Nice improvement. I see extra detail and sharpness without over doing it. Both images are superb. I'm planning a session on M42, shortly, but there is no chance I will get close to your result. Congratulations on your superb work.

Transformed! A really good M42, now.

Point of interest: the bottom half of the nebula, in this rendition, is brown and dusty. In most renditions the red emission still dominates in the lower half.  In some, there is a strong colour transition, but in the reds, where yours turns into brown dust. I find your version perfectly credible and am simply interested in the emission/reflection balance, brown dust being reflection. Essentially, I think your image may be onto something.

What a beautiful image. I'm almost speechless. The whole thing is so delicate and detailed, and the colour is spot on.

Thank you Olly! I recall your version from last year well - something for me to aim for in the future!
 

although technically HaRGB, the Ha was only very slightly used in channel combination, it’s effectively a true colour image hence why the brown dusty areas may have turned out the way they did.
