1000 Oaks narrowband filter

Hi,

The person I bought my original scope off gave me this in 1.25”. Is it a uhc, oiii or what? What is it good for?

Found it. Also a chart saying it’s a UHC w/red. Not sure what the W/red is about. 

How does this compare to say the Astronomik UHC filter?

Looks like UHC judging by the spectral graph...

Oh, and it's good for observing nebulae.... the contrast is increased and makes the nebula pop out.. this filter will help you see fine structure and detail on many nebulae.... down here my favourite nebula in the eyepiece is the Carina, without the filter you can see nebulosity but with this filter the view is almost like a mono photography... it's amazing how much difference a UHC filter makes.

What’s the difference between this 1000 oaks one and this Astronomik?
