* These filters are custom made and are designed to fit over the objective end of your telescope tube assembly, or dew shield, as illustrated above. The various sizes listed refer to a "range" from which you'll select your filter. For example, an Astro-Physics Traveler 105mm refractor has a dew shield with an outside diameter measuring 4.94". You would purchase a 4.6"-5.5" Class A, B or C filter as as it falls within that "range". Thumbscrews on the new design allows a small adjustment for attachment to your tube assembly or dew shield.
During checkout, in the NOTES SECTION please indicate your optical tube or dew shield (if applicable) OUTSIDE DIAMETER.
