IC 5070 - HOO
Photo description / processing
???? Pelican Nebula (IC 5070) • Mosaic
A deep dive into the Pelican Nebula, an active star-forming region in the constellation Cygnus, captured from Mallorca. This image is the result of three nights of data acquisition, combined into a mosaic that reveals the intricate details of cosmic gas and dust.

Location: Mallorca, Spain
???? Acquisition Data (Lights)
This project relied on precise tracking and significant integration time using a dual-band narrowband filter to cut through the noise:
-
Mount / Mode: Mosaic in EQ (Equatorial) Mode
-
Filter: Dual Band (H-Alpha / OIII)
-
Total Integration Time: ~16.2 hours split across 3 sessions:
-
Day 1: 217 x 90s (GAIN 60)
-
Day 2: 217 x 90s (GAIN 60)
-
Day 3: 215 x 90s (GAIN 60)
-
???? Processing Workflow
The processing focused on maximizing the contrast of the gaseous structures using an HOO palette and strict noise control:
-
Pre-processing & Stitching: Stellar Studio and Siril for registration, stacking, and mosaic stitching.
-
Gradient Removal & Star Separation: Gradient extraction via GraXpert followed by star removal using StarNet.
-
Background Detail (Starless):
-
Enhanced using Seti Astro Suite Pro.
-
Advanced sharpening and noise reduction on the starless background with Cosmic Clarity Sharpen + Denoise.
-
-
Color & Stretching (Siril):
-
Channel mixing utilizing the Veralux Alchemy (HOO) palette.
-
Non-linear stretching via Generalized Hyperbolic Stretch (GHS).
-
-
Final Touches: Star recombination with StarNet Star Recomposer and final contrast adjustments using Veralux Curves.
