Capturing the Sadr Region in SHO: A Color Camera's Journey
Last night, I embarked on a rewarding astrophotography endeavor, adding six hours of data using an SII filter to my existing image of the Sadr region. For a while now, I've been experimenting with SHO (Sulphur, Hydrogen, Oxygen) imaging using my ASI585mc Pro color camera, and I'm excited to share the results.
While the finest details might not hold up to extreme zooming compared to monochrome setups, I'm genuinely thrilled with the overall quality and aesthetic of the complete image. It's a testament to the fact that shooting SHO with a color camera can be incredibly sustainable and, in my experience, has revitalized my passion for the hobby. The urge to revisit existing targets with this technique has been reignited, and I can confidently say this is my gateway drug into the world of monochrome imaging.
My Setup:
- Telescope: SVBONY SV503 70ED
- Camera: ASI585mc Pro (cooled to -10c)
- Mount: Star Adventurer GTi
- Guiding & Imaging Control: ASIAIR with an ASI120mm
Acquisition and Processing:
All data was stacked and preprocessed using Siril, followed by meticulous editing in Photoshop to bring out the vibrant details of the Sadr region.
The Image:
This experiment has truly opened up new possibilities and renewed my excitement for exploring the cosmos. I encourage anyone with a similar setup to give SHO imaging with a color camera a try – it's incredibly inspiring!
