Sky-Watcher 2" Light Pollution Filter

2" for use with Skywatcher 130PDS telescope and Nikon D5100. 1st impressions are good for a filter at this price. Light pollution from my location tends to be orange sky glow from high and low pressure sodium street lights. As expected there's no effect with newer LED lighting. There's definitely a noticeable and decent reduction however, it's shown up how much I needed to take flat files. Worth buying.

Cuts out the light pollution well, darkens the sky and improves contrast. Happy with it.

Good value does exactly what it for Blocks a high level of light pollution

Not had much opportunity to use this product as the weather has been so poor we have not had clear skies for Astro Photography. The one trial done it appears to work OK.
