Cosmic Butterfly in The Sky
Price range: $10.00 through $41.00
Description
A glowing red-orange “butterfly” spreads its wings across the summer Milky Way. This is the Sadr Region — the heart of a vast star-forming complex in Cygnus centered on the brilliant star Sadr (γ Cygni). Massive clouds of hydrogen gas, lit from within by clusters of hot newborn stars, stretch for hundreds of light-years and create one of the richest and most colorful areas in the entire night sky.
This 20-hour narrowband image was captured from my Bortle 6 backyard in Williamsburg, Virginia, using the SvBony SV550 80 mm triplet APO and a 7 nm dual-band filter. The long integration brings out the delicate filaments and dark dust lanes that give the region its unmistakable butterfly shape — a perfect blend of beauty and raw cosmic power.
