Great filter for anyone in light polluted skies Review by Josh Wilson

Rate This Product

I bought this filter to take back my sky, which was being ruined by light pollution. I had high hopes for this filter and I still do when ever I want to see more of a nebula.

The 7nm bandpass of O-III molecules, which are green in the light spectrum, gives stars a green tint and dims alot of stars. But you should expect this because of the narrow bandpass (hence the name of this product). With this filter I can find the Ring Nebula very easily and the Lagoon fills the entire FOV. The Dumbbell is also spectacular, and for the first time, I was able to see the reason it was named the Dumbbell Nebula. I would definitely recommend this filter for anyone in light polluted skies.

Clear skies and great observing, Josh (Posted on 7/22/12)
