Does anyone know of a website or other resource that lists nebula and whether one filter or another is superior for certain observations.. for instance whether a Broadband, Narrowband, Oxygen-3, Hydrogen-Beta or other spectral line filter would achieve the greatest contrast on a specific nebula? I don't have any of these filters, but I was thinking about getting a Narrowband and hoping that would be a great one for starters. Which type is your favorite? <br /><br />Also, I don't have any 2" eyepieces. (My longest focal length is a 32mm plossl) Any opinions regarding investing in 2" eyepieces? <br /><br />thanks <img src="/images/icons/cool.gif" />
