M20, The Trifid Nebula: A Budding Astrophotographer's Second Capture
It's always exciting to see the universe through new eyes, and this stunning capture of M20, also known as the Trifid Nebula, by a fellow astrophotographer is no exception! This marks the photographer's second image using their gear, taken in a Bortle 5 sky condition in Maryland. What's particularly impressive is the introduction of calibration frames – flats, darks, and biases – a crucial step for any aspiring deep-sky imager.
The Gear Behind the Stars
The journey into capturing such intricate details of the cosmos requires a well-chosen setup. Here's what was used for this impressive shot:
- Mount: AM5N
- Scope: FRA400
