A Sagittarius triplet – M8, M20, and NGC 6559

This so far is my favorite image! Nearly 21 hours of data (taken across 4! nights) and 3 hours of processing went into this huge project. I love the color range so much – golden milky way stars, pink lagoon nebula, and light blue trifid reflection.

– taken across 4 nights (8/7/2021, 8/8/2021, 8/11/2021, 8/14/2021) from Sharon, CT
– used my old violin strings to create diffraction spikes
– 414 x 3′ light frames – total 20.7 hours of integration time
