Cygnus Region: A 30-Minute Dual Narrowband Mosaic - Seeking Punch!
Hey fellow stargazers!
Last night, I ventured into the heart of the Cygnus constellation, capturing a stunning 6-panel mosaic of a small section of this rich celestial territory. The gear for this endeavor included my trusty Sony A6500 camera, an STC dual narrowband filter, and the sharp Samyang 135mm lens. Each panel was captured with 5 x 1-minute exposures, totaling just 30 minutes of integration time.
Here's the image:
Now, here's where I'm hoping for some community wisdom. While I'm pleased with the overall stitch and detail, the image feels like it's missing that "in your face" punch. I understand that 30 minutes isn't extensive integration time, but is there anything I can do in processing to make it look more powerful? I've tried pushing the saturation, but it quickly starts to look overdone, and I feel like something essential is still missing.
Acquisition & Processing Details:
- Camera: Sony A6500 (modified)
- Lens: Samyang 135mm
- Filter: STC Dual Narrowband
- Location: Bortle 5
Workflow:
- AstroPixel Processor (APP): Mosaic integration (6 panels) including calibration, normalization, and blending.
- PixInsight: Applied Automatic Background Extraction (ABE), BlurXTerminator, an arcsinh stretch for star preservation, histogram normalization/stretch, Curves Transformation, Narrowband Normalization, and StarXTerminator.
- Photoshop: Performed targeted color tweaks using Curves and Selective Color, cleaned up any halos, and applied local brightness/contrast adjustments.
- Luminar Neo: Made minor global balancing adjustments for the final presentation.
I also referenced some existing images of the Cygnus region to guide my color balance.
I'm eager to hear your thoughts and any tips you might have for bringing out more power and vibrancy in narrowband mosaics, especially with limited integration time. Let's discuss!
