This is my take on IC1805 The Heart Nebula. I struggled to find a good color balance with narrowband filters in this image, but I think I managed to find a good balance. I wish Ha nebulosity's background were a bit brighter, but I think I'm happy with this image.
I hope everyone enjoys this image.
Please provide me with feedback, good or bad, to help me improve.
Here are the steps performed on this image:I took the subs went through the subframe selector, blink, and NSG. Stacked the final results.
I used Pixel Math and output an SHO image (image1).
I also used the following Pixel Math to get a second image (image2)
- R = "(0.8*Sii)+(0.2*Ha)"
- G = "(0.8*Oiii)+(0.2*Ha)"
- B = "Oiii"
I then used Pixel Math to combine them since I found things I liked in both images. I discovered that the SHO image had better details in Mellote 15, and the PixelMath image had better details in the outer edges and the dark structure.
- (image2*.80) + (image1*.20) = image3
I had tried a few different variations before I got the above image. Once I got the results I wanted, the following steps were performed in PixInsight:
- Background Neutralization
[*]- Auto Color
[*]- EZDenoise
[*]- Histogram Transformation
[*]- SCNR (Remove Green)
[*]- Extract CIE *L Component
[*]- LRGB Combination
[*]- Curves Transformation (x4 with multiple masks)
[*]- SCNR
[*]- HDR Multiscale Transform
[*]- Starnet++
[*]- Morphological Transformation
[*]- Dark Structure Enhance
[*]- Local Histogram Equalziation
[*]- Color Mask (Blue)
[*]- Curves Transformation with the above mask
[*]- Color Mask (Yellow)
[*]- Curves Transformation with the above mask
[*]
I then took it into Photoshop, did some minor levels and contrast tuning, and watermarked the image. I hope this was helpful and if anyone has any different ways of doing this, please let me know.
