Description:
I observed this old favorite to test out my newly arrived Orion Ultrablock
narrowband filter. I found, by holding the filter between my eye and EP, and
moving it in and out of my field of view, I was able to detect significant (imho)
differences. I found that, especially with averted vision, I could see a greater
extent of the nebula. Little, if any, additional detail was visible, however the
increased size was quite noticable.
