Sky-Watcher N-254/1250 DOB 10 "FLEX is a foldable / telescope mirror with a diameter of 254 mm on a Dobson box azimuth mount.
The classic Dobson system has been modified to achieve higher mobility. The truss tube has been constructed in a way allowing for quick spacing at the observation site, instead of a 120 cm tubular tube we move the assembled tube to a length of about 90 centimeters. This telescope, when unfolded, is easily collimated using a laser collimator, while the lattice is rigid enough to maintain the correct collimation during the whole observation session.
The bearings in the azimuthal axis allow the telescope to be rotated precisely using the minimum force. When setting the height, we can adjust the pressure continuously.
The telescope is equipped with the Crayford's precision eyepiece, allowing the use of 2 "and 1.25" glasses
In addition to astronomical observations, this telescope works great in observing and photographing aircraft at cruising altitudes

This device focuses a lot of light. Looking directly at the sun through this device can result in partial or complete loss of vision. For the observation of the Sun, we recommend the safest method of spectacle projection, that is, projecting the image of the target of our day star on a piece of paper.
