IC1396: A Glimpse of the Elephant's Trunk
Behold the majestic beauty of IC1396, specifically a striking crop of its renowned Elephant's Trunk nebula. This image, brought to life through meticulous astrophotography, offers a detailed view of this iconic celestial formation.
The Journey to Capture This Celestial Wonder
The creation of this image involved a dedicated and precise workflow, utilizing specialized equipment and software:
Imaging Setup:
- Telescope: Askar V with an 80mm reducer (384mm focal length).
- Camera: Ogma AP26CC (IMX571 sensor).
- Filters: Antlia Triband filters were used to isolate specific wavelengths of light.
Guiding System:
- Guide Scope: Skywatcher Evoguide 50DX.
- Guide Camera: Player One Uranus C.
- Filter: UV-IR Cut filter to prevent atmospheric distortions.
Mount:
- Mount: Skywatcher Wave 100i, providing stable tracking for long exposures.
Software Suite:
- Acquisition: Green Swamp Server, ASCOM, and NINA were employed for capturing the data.
- Guiding: PHD2 was used for precise guiding throughout the imaging sessions.
Acquisition Details:
This image is the result of a significant investment of time and effort:
- Total Exposure: 549 frames, each at 240 seconds, totaling an impressive 36 hours and 36 minutes of exposure time.
- Calibration Frames: 15 Darks, 50 Dark Flats (Bias frames), and 50 Flats were acquired to calibrate the raw data and remove noise and artifacts.
Processing Workflow:
The raw data underwent a rigorous processing pipeline to reveal the intricate details of the nebula:
- Stacking: Performed using Siril to combine all the individual sub-exposures into a single, high-quality image.
- Processing: Further refinement was carried out in Siril and ON1 Raw MAx 2025, bringing out the colors and structures within the nebula.
- Upscaling: The image was enlarged by a factor of 2 using Seti Astro Suite.
- Cropping & Resizing: The final crop focused on the distinct Elephant's Trunk formation, and the image was resized in Siril to 25% of its upscaled dimensions.
This process highlights the dedication and technical skill involved in capturing and processing deep-sky objects, allowing us to share the wonders of the universe.
