Product description
The FSQ-85EDX is a more mobile version of the FSQ-406EDX4 for lovers of wide-field deep sky imaging.
Like its predecessor, it is based on an apochromatic Petzval quadruplet formula including ED glass. With a focal length of 450 mm and a flat field covering 5.6 degrees over the sky, this refractor is ideal for photography. It is delivered with a 1.01X corrector to make the most of recent sensors with smaller and smaller pixels. The image circle is 44 mm.
The rack-and-pinion focuser is deliberately oversized to improve accuracy and efficiency. It is controlled by a double system of 1/7 ratio wheels and equipped with a CAA (Camera Angle Adjuster) for photographic framing. The retractable dew shield saves space.
A focal reducer is available as an option to transform the telescope into a true high-end 328 mm astronomical telephoto lens, open at 3.9, with a 7 degree field of view on the sky and a 40 mm image circle!
