APJ Video Brief (#12)- Best OSC filter to image M42?
There are so many filter choices for One-Shot-Color (OSC) imaging. What filter is best for which nebula? In this video, I tested 4 different filters on M42, the Great Orion Nebula. All the results look different, but I found a combination of two filter results that yielded the best looking overall M42 image.
