Description

I took advantage of a few rare hours of clear skies to get some longer exposures on M42. I had originally planned to combine this with some previously acquired shorter exposures, but I shot those with an L-extreme filter and didn't like the combination. I'm hoping to get some shorter exposures in broadband before the end of M42 season.
