M100
About this celestial object
M100 unfolds as a grand‑design spiral, its fine arm segments gracing the spring sky.
M100 is among the large, symmetric spirals of the Virgo region and hosts numerous star‑forming regions in its arms.
212 frames at roughly 4° elevation capture the core and the first arm segments despite middling transparency.
A 250 mm f/5 wide field emphasizes its embedding in the Coma Berenices region.
