I am interested in viewing nebula & other deep space objects. What do you recomend for my 1st filter. uhc type lpr filter or o-III type filter. I have a great viewing spot 15 miles from the nearest small town & 25 from the nearest city.

Thanks

Brian

What kind of aperture are we talking about?

Your best bet is the UHC, since it works on the largest selection of objects. By "objects" I mean nebulae. Remember, one of these filters won't do PEA-TURKEY for any object that radiates in starlight: stars, galaxies, open clusters, globular clusters, reflection nebulae. wink
