M16, the Eagle Nebula, is very difficult to photograph from Pommier Observatory, as it is low on the southern horizon requiring it to be imaged through a great deal of atmosphere and then only intermittently when it appears between tall trees. The hydrogen-alpha filter and the adaptive optics were used to try to mitigate the atmospheric effects as much as possible. For a description of this object, please see the LRGB image of M16 in Nebulae.
Exposures: Ha:R:G:B=270:60:50:50 minutes=7 hours, 10 minutes total exposure at f/7.5.
