My image of the Tulip Nebula (Sh 2-101) and its dusty surroundings

Here’s my image of the Tulip Nebula (Sh 2-101) and the surrounding dusty region in Cygnus. I captured this over three months, of which only seven nights were usable thanks to the weather!

If you’re interested, I’ve documented my project over on my YouTube channel:

Processing Details:

1. Stacking in WBPP
2. StarXtermintor SHO images
3. Linear Fit the SHO images
4. RGB-SHO colour combination/mapping
5. BlurXterminator
6. Narrowband normalisation
7. Permanent stretch via histogram transformation
8. Selective colour correction
9. Masking a slight curves adjustments
10. RGB Stars generation using channel combination
11. BlurXterminator on RGB stars
12. SPCC for colour correction
13. GHS for permanent RGB stars stretch
14. Adding the RGB stars to the SHO image via Pixelmath
15. Photoshop for final cropping and small adjustments
