Description

A quite difficult objet if you want to get out the faint structures. Needs long exposures with a transparent sky. 100 min exposure with 10 min sub-exposures were not enough on a C8. Ha needs longer sub-exposures and the OIII was noisy because of the Moon (5 nm bandwidth does not completely stop the Moon light which is stronger in the blue-green spectrum)
