The William Optics FLT 132 APO Telescope is a high quality Apochromatic Imaging and visual use telescope with an aperture of 132 mm and a focal length of 925 mm or an f-ratio of f/7. This FLT 132 APO Telescope from William Optics can be used with a camera mounting system, with various T-mounts for cameras (not included), or equally well as a visual observing instrument. Features a top-quality triplet air-spaced objective, designed by a leading designer with FPL-53 glass. The telescope utilizes precision optics with STM coatings. This FLT 132 APO telescope is extremely sharp and has great color correction which is ideal for astrophotography. It is a joy to use. You will be blown away by the small details you can observe through this APO 132 mm; fine details of DSOs, stunning resolution both visually or for astrophotography. Until yesterday this was only something you could dream about, at this price!
You will be astonished by the images you get. If you wish to take great astro-images with a high quality APO refractor, this William Optics FLT 132 APO Telescope is the ultimate way to achieve your imaging goals, with its focal length of 925 mm. Its FPL-53 glass air-spaced Triplet lens design provides images with extreme sharpness, clear details, with APO color correction. Just as great for doing visual observations. This William Optics FLT 132 APO Telescope will be a main attraction and a hit at every star party you attend.
Incorporates the 3.3" WO Rack & Pinion heavy duty focuser, which is ideal to use with astro-imaging, providing ideal focusing ability with no image shift. The 132 mm objective is a great size for both wide-field and planetary visual observations, and its apochromatic performance makes it ideal for imaging. This is a do-it-all telescope with stunning optical performance. It is worthwhile to note that the size and weight of the telescope will require a suitable mount in order to do astro-imaging.
New for 2019: Now, when you purchase this FLT 132 APO Telescope from William Optics, you will be assured that the optical performance of this telescope achieves a Strehl Ratio of > 0.92 (Strehl) because they are testing each optical system on a Zygo Interferometer to confirm that performance specification. In addition, each telescope is star tested by William Optics professionals to guarantee the ultimate in optical performance. A printed report of the Zygo testing results is available at extra cost.
The FLT 132 APO Telescope from William Optics incorporates the finest triplet objective with a new center element, and a steel lens cell. The steel lens cell has been proven to reach ambient temperature quickly, and during temperature changes it has much less distortion than occurs with the ordinary aluminum cells. This is important in a large objective such as the 132 mm because it prevents lens pinching.
Includes dual Mounting rings and 2 Guiding rings, 3.3" Dual-speed WO Focuser which is 360° rotatable for convenience, Losmandy style Dovetail Plate, CNC Carrying Handle, and the new innovative Bahtinov Mask cover. It can be used visually or with digital cameras, and is compatible with a Field Flattener (optional purchase). This telescope package also includes a WO 3" RotoLock Adapter, and a premium soft Carrying Case for storage and transportation. Note: The 2"-1.25" RotoLock Adapter is an optional purchase and is not included with this package.
Introducing a first innovative feature in the industry: Now this FLT 132 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 telescope. 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.
