Discovered 1780 by Pierre Méchain.

M78 is the brightest diffuse reflection nebula in the sky. Discovered by Pierre Méchain in early 1780, Charles Messier added it to his catalog on December 17, 1780. It belongs to the Orion complex, a large cloud of gas and dust centered on the Orion Nebula M42/M43, and is about 1,600 light years distant. It is the brightest portion of a vast dust cloud which includes NGC 2071 (northeast, lower right in our image), NGC 2067 (close northwest), and very faint NGC 2064 (southwest), all visible in our image. Together with some other nebulae, including NGC 2024 (Orion B) near Zeta Orionis (sometimes called the Flame Nebula), all these nebulae are associated with the molecular cloud LDN 1630 (from Lynds' Catalogue of Dark Nebula), a part of the Orion complex.

마음 먹고 러셀 크루먼의 사진에 도전해 보고 싶은 대상이었지만 구름이 방해를 하고 말았습니다.
결국 총 이틀 동안 4시간 가까이 찍었지만 구름 때문에 결국 1시간 반 불량밖에는 정보를 얻는데 실패 했습니다.
그리고 그 나머지 마저도 투명도가 좋지 않아 어두운 부분은 찍히질 않고 말았습니다.
내년에 15인치로 도전을 해 보아야 겠습니다.
