The William Optics Star 71 II Limited Edition Blue Refractor is a four-element design Petzval telescope, and is provided in a beautiful blue and white color. Because of its Petzval 4-element design, it produces a flat image plane with an image circle over 45 mm, and does not need an additional field flattener to accomplish this. This Star 71 II Limited Edition Blue Refractor from William Optics is beautiful to look at and it will allow you to take beautiful astro-images too, with your own preferred imaging equipment.

This Blue and White Imaging refractor from William Optics uses a patented four-element design to achieve a flat image plane with extreme sharpness out to the edge of a 45 mm image circle. Its full image circle is 48 mm in diameter. The William Optics WO Star 71 II Limited Blue Edition Petzval Imaging Refractor produces apochromatic grade color correction images to provide spectacular astro-images of your favorite objects.

Introducing a first innovative feature in the industry: Now this Star 71 II Limited Edition Blue Refractor from William Optics comes standard with a dust cover that has a built-in, clear Bahtinov Mask for perfect focusing every time. Simply remove the flat front cover plate, leaving the dust cover cuff in place on the scope. Point the scope at a bright star, and focus carefully. When the bright central diffraction spike looks exactly centered inbetween the other two spikes forming an "X", then your scope is in exact focus for stars. Remove the dust cover cuff carefully from the objective end of the scope, and you are ready to image.
