When to use UV/IR cut filter
When imaging with a refractor, is a UV/IR cut best left on all the time, or only with blue?
If using an OSC CCD, any detriment to leaving an UV/IR filter in place on the front of the camera? Any detriment stacking one on top of an H-a filter? (I extract the red channel of OSC H-a filtered images)
Appreciate thoughts here, as I have read conflicting advice.
