We recommend this set for all astronomy enthusiasts who enjoy observing the Moon and planets. Baader Q-Turret Quadruplet Eyepiece Revolver: It allows for changing magnifications in seconds. The eyepiece revolver features a 1.25" connection on the telescope side and accommodates four 1.25" eyepieces or adapters simultaneously. Baader Classic Orthos - 18 mm / 10 mm / 6 mm: Orthoscopic eyepieces provide the best sharpness on-axis and very high contrast, which is why Orthos are often used for lunar and planetary observation and photography. The three focal lengths of the set cover the entire magnification spectrum for these objects, especially in combination with the Barlow. Baader Plössl Eyepiece 32 mm: With extension sleeve and eyecup - fully multi-coated - for maximum field of view with 1.25". Baader Q-Turret 1.25" Barlow: Magnification factor 2.25x and 1.3x - one of the best 2-element Barlow lenses we know for observation and photography. The Barlow lens offers the highest contrast, keeping the image bright and sharp. You can also screw the Barlow element into the Q-Turret eyepiece revolver.
