Quickshot: The Elephant Trunk Nebula (SHO with RGB stars)
I realized that I never processed the Elephant Trunk Nebula that I started taking at the end of 2024. I had expected to go back and get more data but never did, and now it’s too low.
This was about 12.5 hours of RGB & SHO data (300s and 600s, respectively), with an SHO nebula and RGB stars.
Acquisition Details
- Mount: Astro-Physics Mach2GTO
- Telescope: Takahashi FSQ-106EDXv4
- Camera: ZWO ASI6200MM
The data for this was captured over several nights (December 12, 21, 22, 30, and 31, 2024 and January 1, 2025), gathering 102 unguided subs for a total of 12.42 hours.
It’s a single framing (not mosaic), based on what could nicely fit on the sensor.
Per-filter totals for the Elephant Trunk Nebula:
- Red: 2.08 hours (25 subs)
- Green: 1.25 hours (15 subs)
- Blue: 1.25 hours (15 subs)
- Sii: 3.17 hours (19 subs)
- Ha: 3.00 hours (18 subs)
- Oiii: 1.67 hours (10 subs)
- total: 12.42 hours (102 subs)

Processing details
All processing was done in PixInsight, using several plugins and scripts. These were basically the same steps I did for the Flaming Star so I won’t repeat them here.
