Hello AP'ers,
Hopefully everyone is having a great start to the holidays. I dipped back into my pool of data and pulled the IC1396 masters back out and sat down to take a completely new look at the data using more up to date methods I have been employing for processing.
BXT was used on this process run, but it did not really have much of an effect other than managing star sizes. In terms of sharpening in the nebula regions, it had very little effect. The total integration time is 65.5 hours on the E160ED -- which is a lot!
Some notes here on the processing:
Linear Mode Steps:
- BlurX on each master (HA, OIII, SII) separately.
- NoiseX on each master separately.
- StarX on each master
separately.
- DBE on each master, using the same model
Non-Linear Mode:
- Stretch each master separately using Histogram Transformation
- Combine masters using Dynamic SHO Method
- Create Lum Mask using Extract CIE L Component Button
- Mask and hide the mask
- Curves Transformation for mild boost in Saturation only
- HDR Multiscale Transform
- Local Histogram Equalization
- Remove Mask
- Individual stretch on each Star master separately
- Curves on stars to adjust saturation for brighter colors
- Combine Stars using Pixel Math into their own master
- Screen Stars onto Image using Pixel Math
- Second pass of NoiseXTerminator to clean up residual noise
- Final DBE (same model as before)
Not very complex and did not take me much time as the data was pretty good to start with.
Some things I like about this version is that the colors transition much more naturally and feel more alive. The overall nebula feels and looks smoother to me with less chunkiness. The overall color palette is more charming, let's face it the burnt orange
and blue common HST palette starts to look the same. This feels more like an expression of the overall distribution of the data collection (which was heavily in favor of OIII as that was close to 50% of the time spent). The 3 PN's in the image are all very
visible without needing to hunt them down or look at a starless version for them to pop, and finally managing stars in this manner allows for much better control of their size, brightness, and colors.
Let me know your thoughts, and Merry Christmas.

Bill, this is a beautiful revisit of the data! I love the colour palette and the more subtle transitions as you indicated was your intention. Nicely done!

Here is the exact same image, just in the traditional HST palette. For comparison.

Aaaaand one more. 🙂
HST-ish, but retains the green hues in the center that give a green-teal-blue transitions that highlights the elements better, IMO.
