Abell 39 Sw200p CC Asi294mcpro g125 22L 300s -10c 31.05.2024 1h50m L-Pro Mirante do Morro

Revisitando Abell 39, uma das minhas nebulosas planetárias favoritas, se não a favorita. Seu formato circular quase perfeito e sutil azulado a tornam bem interessante. É bastante tênue e sua captura, mesmo com equipamentos que auxiliam na automatização, foi um desafio! Captura feita na Chapada dos Veadeiros, Bortle 1, usando filtro L-Pro.

 

Revisiting Abell 39, one of my favorite planetary nebula, if not the favorite. Its almost perfect circular shape and subtle bluish hue make it quite fascinating. It is very faint, and capturing it, even with equipment that aids in automation, was a challenge! The capture was made in Chapada dos Veadeiros, Bortle 1, using a L-Pro filter.
