This means you can choose any of the standard 1.25 inch astronomy eyepieces. There's an incredible range of options open to you in terms of quality and price.Once you decide what level of quality you want (ranges from generic Chinese knockoffs to Televue, Pentax, Docter) then you pay more money for a wider, flatter, color corrected view through the eyepiece. So a Televue Delos which would give you around 30x would cost you $330 and show an afov of 72 degrees, while a Televue Plossl with around 30x would cost about $100 but only show a 50 degree afov. Both eyepieces will display a terrific image, but you'd pay a $200 premium for the sensation of greater immersion in the scene before you.Going down the quality scale, You could choose to spend as little as $30 to $40 for the same magnification from a generic manufacturer, but the view will be blurry around a good part of the image and the colors are going to look odd.You won't be able to use any of the Leica, Kowa, or Swarovski eyepieces without a special and costly adapter but similar or higher quality astro eyepieces are readily available to you, usually at a fraction of the alpha prices.You can check out Cloudy Nights, particularly the eyepiece forum, for all the latest on astro eyepieces.Best to you,JerryPS: The astro eyepieces are arranged and sold by their focal length, not magnification. So a 30 mm eyepiece is not a 30x eyepiece. You need to find the focal length of your scope and divide that number by the focal length of the eyepiece to get the magnification of the eyepiece on your particular scope. So, if the RSPB had a 600mm focal length then you would divide that by the 30mm focal length of the eyepiece  to yield a 20x magnification. To get a 30x magnification you'd need a 20mm eyepiece if you have a 600mm scope. I don't have any idea of the actual FL for your scope; usually they're 480 to 600mm but you need to find an actual number before you can choose an appropriate eyepiece for the 30x magnification you mentioned.</blockquote>
