The William Optics Gran Turismo 81 Imaging APO Telescope is a high quality Apochromatic Imaging optical telescope with an aperture of 81 mm and a focal length of 478 mm or an f-ratio of f/5.9, without the optional Reducer/Flattener.

If you wish to take great astro-images with a high quality APO refractor, this William Optics Gran Turismo 81 Imaging APO telescope is a good way to obtain your goal. Its FPL-53 glass APO design provides images with extreme sharpness, clear details, great color, with APO grade color correction. If you add the optional 0.8X Flattener/Reducer lens, the focal length is shortened. Then the image circle will be full frame compatible, and perfect for imaging deep sky objects.

Introducing a first innovative feature in the industry: Now this Gran Turismo 81 Imaging APO Telescope 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 telescope at a bright star, and focus carefully. When the bright central diffraction spike looks exactly centered between the other two spikes forming an "X", then your telescope is in exact focus for stars. Remove the dust cover cuff carefully from the objective end of the telescope, and you are ready to image.
