In recent years, not only the single narrowband filters are chasing narrower band width, but also the dual band filters. From 7nm to 3nm, manufacturing process improved so fast!

But one thing is missing, halo control! The halo around stars is like a nightmare when you shoot some famous deepsky object!

Why only chasing super narrow bandwidth, but not deal with the halos?

The reason is, halo control is hardest part in manufacturing.

Most people get used of it!

Until now!
