I was a bit skeptical when a good friend of mine suggested that I pick up this filter. I have had some filters in the past and got rid of them because I generally dislike the green coloring that they provide to stars and nebulas. After a bit of nagging by my friend I went ahead and pulled the trigger. So on a Saturday night at my clubs public outreach I put the filter into the Ethos 13 and then inserted it into the focuser of the clubs 18" F4.5 Starmaster in the middle of light polluted Miami, Florida. WHOA NELLY!!! What a view!!! I had never seen M42 pop out like it did, I was instantly a happy customer. I decided to remove the filter to compare the views and I just had to put it right back on. Without the filter the nebula was there but there was a large amount of skyglow and lack of detail. With the filter the sky goes black and the contrast on the nebula is raised quite a bit providing the most pleasing image. Unfortunately this was back in March 2010 and the rainy season in Miami was about to start so I have not been able to use it since. I can't wait to get this out to a dark site and try it on a lot more objects. My advice, GO GET ONE!!!

I`ve had both of these DGM filters, VHT and NPB, for over a year and I`m always amazed at how well they perform. Under dark skies bright nebula seem to be "switched on" with the filter in place.
And you can`t beat the price, on sale for 55 bucks at this time!

Cheap but good. Really brings out the Veil, M27, North American and Lagoon.
