Andrômeda M31 WO66 Starless

Galáxia de Andrômeda - M31 e suas vizinhas M32 e M110. Maior galáxia visível no céu, situada a 2,5 milhões de anos-luz, possui diâmetro de cerca de 220 mil anos-luz com mais de um trilhão de estrelas — o dobro da Via Láctea! Minha melhor captura desse objeto até o momento. Aparece tem um "amp glow" à direita pois o empilhamento é de uns meses atrás, hoje já sei me livrar dele. Na segunda foto, um belo starless.

 

Andromeda Galaxy - M31 and its neighbors M32 and M110. The largest galaxy visible in the sky, located 2.5 million light-years away, with a diameter of about 220,000 light-years and containing over a trillion stars — twice as many as the Milky Way! My best capture of this object so far. There's some "amp glow" on the right since the stacking was done a few months ago, but I’ve learned how to get rid of it since then. In the second photo, a beautiful starless version.
