1.25" NPB Nebula Filter-Cosmetic 2nd-L8

Observed the orion nebula with this filter it defiantly pop's in detail.

I decided to purchase this filter based on excellent reviews in Astronomy magazine and on Cloudy Nights. I recently had the chance to try it out in moderately light polluted skies. When viewing the Lagoon Nebula (M8) it made a big difference. It also helped increase contrast with the Dumbell Nebula (M27) and the Ring Nebula (M57). One thing I really like about it is that it doesn't turn everything green like my other UHC filters. It gives the stars a slight reddish tint but it's hardly noticeable to me. This "cosmetic second" filter showed a couple tiny pinholes on the filter surface, but these don't seem to affect the performance at all. I decided to get the 2" cosmetic second NBP filter as well.

Very nice filter. On the first one I received the threads did not mesh well with some of my eyepieces. That must be the "2nd". However I contacted the seller and he sent me a replacement that worked better.

Amazing contrast. I bought the 1.25 inch only. DGM's web site offer's a 1.25 and 2 inch cosmetic seconds combo. I bought mine from Amazon. As promised, I could not see any issues optically. Maybe I saw the pin hole. I'm not even sure. I think I got a real deal here. I'm attaching a sample of the Orion Nebula on the NexStar 5Se 20 sec exposure. I researched this filter and found many found it better than the Lumicon UHC filter! I also use this filter to locate planetary nebula using the blinking method e.g. the Ghost of Jupiter, which looks like a blurry star without the filter. With the filter, I can just make out the nebula. I'm trying to image it and will use the DGM for sure to bring out contrast. Also, check out reviews on Cloudy Nights site.

An got to have for Nebula viewing!
