NEBULA FILTERS for TELESCOPES

In this video I am going to explain all about nebula filters for a telescope.  I will explain first what nebulae are so you can understand how a nebula filter works. Then I will explain the difference between the various nebula filters.  Next I will show you the results of some testing I did of various nebula filters of various brands on various nebulae and show you how well each one performed on the nebulae I looked at in two different telescopes.   Finally, I conclude by explaining my reasoning for recommending that if you purchase a nebula filter that you should first get a UHC filter for your telescope.  Keep in mind that some of these nebulae are very faint and that another extremely important factor to seeing them is to go to a dark sky site.  Dark skies are vital to seeing nebulae.
