Description

Here is the region from the center of the Heart Nebula to the Fish Head Nebula, in Ha. shot over 2 nights. The Moon has been very bright, but the 3.5nm very narrow Ha passband still gathers great data as long as I am shooting generally away from Luna. Need to take advantage of clear nights even if the Moon is bright.
