8/2023 RE_EDIT FOR TAIC WORKSHOP
The AstroImaging Channel is doing a workshop on this dataset now with submissions needed by August 13 and the show on August 27. This dataset is available for you to download here: https://www.theastroimagingchannel.org/taic-workshop.htmlI was never fully happy with my processing on this so I reprocessed it myself for the show. I went into it assuming the composition would turn out completely different as I had initially shot this 90 degrees counter-clockwise to how you see it here. After processing it fully, the last thing I did was to begin cropping. After about three successive small crops I ended up rotating it within a few degrees of the original. The colors and contrasts are different of course.
I hope you will take a shot at processing this!

Original Write-up
It's unclear to me whether NGC 2467 refers to the Nebula or the Star Cluster. I see it referred to both ways. There are two open clusters, Haffner 18 and 19, that are separately called out. My processing goal was to present the nebula so the star clusters are less prominent here.
The Nebula was reasonably strong in all three narrowband channels. Strong enough that I did a straight SHO combination and did not need to use a Psuedo-Luminance to control noise levels. I merely did a linear fit of the SII and OIII data to the Ha and then used the old color calibration tool in PI to get a range of colors and best separate the structures. From there I did small color tweaks to my taste. Stars are RGB.
There are two bright circular areas represented in orange here. The smaller one on the left is the star FM3060a, a brand new star still ensconced in the gas cloud that formed it.
