Its FPL-53 glass air-spaced Triplet lens design provides images with extreme sharpness, clear details, with APO color correction.
Incorporates the WO 3.3" Rack & Pinion heavy duty focuser, which is ideal to use with astro-imaging, providing ideal focusing. The 102 mm objective is a great size for both wide-field and planetary visual observations, and its apochromatic performance makes it ideal for imaging. 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 Gold GT102 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.
Includes dual Mounting rings and 2 Guiding rings, 3.3" Dual-speed R&P Focuser, Vixen 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 premium soft Carrying Case for storage and transportation.
Introducing a first innovative feature in the industry: Now this Gold GT102 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.
