船底座大星云 2x2 马赛克

ETA - Carina 2x2 Mosaic



This is my first successful mosaic astronomy photo, it took me two nights over 9 hours shooting (OSC Camera) and 3 days processing.

I am so happy with the final image over 70m pixel can zoom in and zoom out for the detail.

These is my processing way ,please let me know if you find better way to do it .

1. Mac APP (better finder rename) add key word “Panel” tothe fits name
2. Blink and delete the bad images
3. Group by “Panel” in WBPP and get 4 Master light file
4. After DBE save as fits
5. Astro Pixel Processor Only for 2x2 mosaic , Easy and better than Pi ,But I try a few time then get good results
6. DBE again
7. BlurXterminator - Decon and sharpen the stars
8. HT and STF nonlinear
9. StarXterminator - also generate a star mask
10. SCNR Remove green light of stars
11. NoiseXterminator of nebula
12. Curve adjust the color and exposure of the nebula
13. Pixelmath add star back to nebula
14. Save as 16bit Tiff   
15. import to Lightroom
16. Adjust the basic exposure (Highlights Blacks also Texture and Clarity)
17. LM-Mask and curve adjust the color and detail
18. Orton on light
19. Sharp for web 1920px
20. Save for web 1920px and full size in Jpeg

和楼主之前在 heq5 的皮带改群打过交道，觉得楼主是个挺热心的人，也愿意分享自己摸索的东西。

虽然鸟语看得累，不过107phq确实锐

Great Carina Nebula has been awarded by the head curators!
This is an extraordinary achievement since less than 1% of all photographers uploading to 1x are selected for this award.
