Hello Cloudy Nights,

 

I recently finished processing my image of M42 in tricolor narrowband; however I'm having difficulty trying to get it to look "right." I do like the blue, orange, and purple color palette that I ended up with but in some areas (specifically in the orange) the color looks really blotchy. Also, in the low signal areas, the luminance seems to have blotchy regions (really apparent in the upper left of the image) and there's a lot of really bright pixels throughout the image. Finally, the nebula ended up looking rather blurry, especially on the outer edge, but the stars aren't elongated. My processing was limited to using HDRCombination to preserve the core details, deconvolution, MLT for denoising on the Ha (to be used as luminance, LHE on the luminance, combining in SHO, SCNR to remove green, a series of curves with masks to slowly shift the colors to my liking, ACDNR for another round of denoising, and then two rounds LHE to increase local contrast. Below is a Google Drive link to a folder containing all of the stacked images and the final XISF file and the image posted on Astrobin. I've also uploaded a smaller version to this post. I'd be more than happy to provide any additional information or files if necessary. The images were captures with an ZWO ASI 1600MM Pro through an Orion 8" f/3.9 astrograph on a guided Atlas EQ-G. Any comments, suggestions, and critiques would be greatly appreciated! Thanks!

To me it is too much. Looks unnatural and over processed. Sorry but you asked

That's...a very bright and flamboyant piece of artwork.

 

(Tries not to say anything discouraging).

 

It's certainly revealing and brings to the fore many nebular intricacies...

Very colorful! It gave me a different perspective of the nebulosity. If it were me, I might try doing another version with more natural colors though.

Your processing is cool and artful looking in its own right.  While I'm writing this, several others have replied saying the same thing as I.  You've got some good data there, worthy of another try at the processing to go for a more natural result.  I look forward to seeing it!

 

Best Regards and With Only the Best and Encouraging of Intentions,

Ben

It is interesting and unusual. Actually I like it.

It's not a problem at all! Thank you for the feedback!

Thank you both and I'm glad you like the current version! I'll definitely give it another shot!

Thank you for your reply! This is an Astrobin link to a fantastic image by Marcel Drechsler that has the look I was trying to go for: https://www.astrobin.com/353669/
 

Sure looks different.

Thank you for your reply!

I can't say I got it from there but the astrophysical phenomenon is what inspired the name!

Well, it appears you went very deep...you picked up some pretty faint outer details there. The coloring and style is interesting, rather artistic, but I do think it is a bit over-the-top. I'm partial to more realistic representations, and I think given the depth of the data here you could probably do a lot with the data without pushing it so hard.

Thank you! I'm going to give it another go and try to keep it much more natural!

Belated opinion: If you want to keep the interesting colors, remove the stars. The presence of the stars make the colors chosen seem unnatural. Without them, you have a beautiful abstract painting that resembles the Orion Nebula.
