NGC 1566 The Spanish Dancer

So I am going deeper with this target from my Bortle 8 skies - up to 34 hours of data on my 132mm WO refractor.

I am selecting targets to shakedown all my gear and then get rich data sets as I start planning to do some online courses on PixInsight.

I figure it will be interesting to see what I can do before and after training when I have 50 hours or so of data on my chosen targets!

All LRGB 300sec subs - stacked and processed in PI.

PI Workflow
1. WBPP - high quality / no drizzle
2. Gradient correct all LRGB auto-cropped masters
3. Blur Exterminator (Correct only) the outputs of step 2
4. Blur Exterminator
5. Noise Exterminator (latest AI version 3 - defaults apart from iterations set to 3)
6. Channel combine RGB masters
7. SPCC on combined RGB master
8. Statistical stretch RGB master (defaults)
9. Star Exterminator on Lum master
10. Star Stretch (defaults) on Lum_Stars
11. Statisical Stretch on Lum_Nebula
12. Unsharpmask on Lum_Nebula (gentle < 2)
13. PixelMath combine ~(~Lum_Nebula * ~Lum_Stars)
14. ImageBlend combine Stretched Lum (from step 13) with Stretched RGB (from step 10)
15. GHS Linear - slight rise of black point
16. Curves Transformation - slight rise of Chrominance and Saturation
17. Histogram Transformation - slight lowering of mid point
18. Noise Exterminator (defaults)

So I will look back on this in 6 - 12 months and see how my processing workflow and results may have changed!
