Comet C/2025 R2 (SWAN) – Multi-Perspective Observation Record

Comet C/2025 R2 (SWAN) swept across the autumn night sky, its vivid green coma revealing the pristine ices and dust from the distant reaches of the Solar System.
This composite presents the same comet through three different instruments, each offering a unique perspective of this celestial traveler:

🔹 Top Left: Captured with the LATTE Telescope by the author, and image processed by Dr. Hsiao, revealing the bright nucleus and the delicate structure of its tail in stunning detail.
🔹 Bottom Left: Recorded with the Seestar S50, showing the comet passing near the Eagle Nebula (M16). The image displays a clear motion trail during the exposure, highlighting the comet’s rapid movement across the star field.
🔹 Right: A wide-field image taken with the Canon R6, portraying the green comet suspended before the Milky Way’s central dust lanes—like an emerald adrift in a sea of stars.

Three perspectives, three focal lengths, one cosmic encounter—
a fleeting visitor leaving its luminous trace among the stars and nebulae.
